Abdominal Aortic Aneurysm (AAA) Screening
A way of checking if there's a bulge or swelling in the aorta, the main blood vessel that runs from your heart down through your tummy.
Arterial Blood Gases
This test is used to check the functions of the patient's lungs. Specifically with how well they are able to move oxygen and remove carbon dioxide.
General anesthesia is essentially a medically induced coma, not sleep. The drugs will render a patient unresponsive and unconscious. They are normally administered intravenously (IV) or inhaled. Under general anesthesia, the patient is unable to feel pain and may wake up with amnesia.
This is a coil-spring device used to treat aneurysms.
The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, which is the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one-way flow of blood.
The Arterial is a blood vessel that takes blood away from the heart and distributes the blood to all parts of the body (tissues, lungs, etc.).
An Arterial Duplex is an ultrasound test that uses high frequency sound waves (ultrasound) and a series of blood pressure cuffs to show and measure blood flow in the arteries of the arms and legs.
Arthrography is a type of medical imaging used in the evaluation and diagnosis of joint conditions and unexplained pain. It is very effective at detecting disease within the ligaments, tendons and cartilage.
Asymptomatic means that there are no symptoms. You are considered asymptomatic if you:
Have recovered from an illness or condition and no longer have symptoms.
Have an illness or condition (such as early stage high blood pressure or glaucoma) but do not have any symptoms of it.
A barium enema is an X-ray exam that can detect changes or abnormalities in the large intestine (colon). The procedure is also called a colon X-ray. An enema is the injection of a liquid into your rectum through a small tube. In this case, the liquid contains a metallic substance (barium) that coats the lining of the colon. Normally, an X-ray produces a poor image of soft tissues, but the barium coating results in a relatively clear silhouette of the colon.
Beta-adrenergic Blocking Agents
Beta Blockers are medications that reduce your blood pressure. Beta blockers work by blocking the effects of the hormone, epinephrine, also known as adrenaline. Beta blockers will cause your heart to beat more slowly and with less force, which results in lower blood pressure. Beta blockers also help open up your veins and arteries to improve blood flow.
Blood thinners are medicines that help blood flow smoothly through your veins and arteries. They also keep blood clots from forming or getting bigger. They're used to treat some types of heart disease, heart defects, and other conditions that could raise your risk of getting dangerous clots.
Bone Density Scan
A bone density scan uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. The bones that are most commonly tested are in the spine, hip and sometimes the forearm.
Brachial plexus is the network of nerves that sends signals from your spinal cord to your shoulder, arm, and hand.
Breast MRI (magnetic resonance imaging)
This is a test used to detect breast cancer and other abnormalities in the breast. A breast MRI captures multiple images of the breast. The breast MRI images are then combined, using a computer to create detailed pictures. A breast MRI is usually performed after you have a biopsy that's positive for cancer and your doctor needs more information about the extent of the disease.
Ultrasound imaging of the breast uses sound waves to produce pictures of the internal structures of the breast. It is primarily used to help diagnose breast lumps or other abnormalities your doctor may have found during a physical exam, mammogram or breast MRI. The Ultrasound is safe, noninvasive and does not use radiation. This procedure requires little to no special preparation.
For the bubble study, you will get an intravenous (IV) line in a vein in your arm. A saltwater solution called saline is mixed with a small amount of air to create tiny bubbles that are then injected into your vein. This fluid then circulates up to the right side of your heart and shows up on the echocardiogram image. You may be asked to cough, which briefly increases the pressure in the heart's right side.
Cancer Staging and Re-staging
Staging is the process of finding out how much cancer is in a person's body and where it's located. It's how the doctor determines the stage of a person's cancer.
Cardiac Event Monitor
A wearable cardiac event monitor may be used to diagnose tachycardia. This type of portable ECG device records heart activity only during episodes of abnormal heartbeat.
Of or relating to the heart.
A cardiologist is a doctor with special training and skills in finding, treating and preventing diseases of the heart and blood vessels.
Carotid Doppler Test
A carotid Doppler is an imaging test that uses an ultrasound to examine the carotid arteries located in the neck. This test can show narrowing or possible blockages due to plaque buildup in the arteries due to coronary artery disease.
Computerized Axial Tomography
CT scan images allow the doctor to look at the inside of the body just as one would look at the inside of a loaf of bread by slicing it. This type of special X-ray, in a sense, takes "pictures" of slices of the body so doctors can look right at the area of interest. CT scans are frequently used to evaluate the brain, neck, spine, chest, abdomen, pelvis, and sinuses.
Cine CSF Flow Study
CSF - Cerebrospinal fluid
CSF flow studies are performed using a variety of MRI techniques and are able to qualitatively assess and quantify pulsatile CSF flow.
Claustrophobia is a form of anxiety disorder, in which an irrational fear of having no escape or being closed-in can lead to a panic attack.
Cochlear Ear Implant
A cochlear implant is an electronic device that partially restores hearing. It can be an option for people who have severe hearing loss from inner-ear damage and who receive limited benefit from hearing aids.
Contrast materials, also called contrast agents or contrast media, are used to improve pictures of the inside of the body produced by x-rays, computed tomography (CT), magnetic resonance (MR) imaging, and ultrasound. Often, contrast materials allow the radiologist to distinguish normal from abnormal conditions. Contrast materials are not dyes that permanently discolor internal organs. They are substances that temporarily change the way x-rays or other imaging tools interact with the body.
A CT scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. CT scan images provide more detailed information than plain X-rays do.
CT - Perfusion
A Computed tomography (CT) perfusion of the head uses special x-ray equipment to show which areas of the brain are adequately supplied with blood (perfused) and provides detailed information about blood flow to the brain. CT perfusion is fast, painless, noninvasive and accurate. It's a useful technique for measuring blood flow to the brain, which may be important for treating strokes, brain blood vessel disease, and brain tumors.
A CT arthrogram is a two-part procedure performed to aid in the diagnosis of subtle abnormalities in the joints of the extremities, including the shoulder, elbow, wrist, hip, knee, and ankle.
Discography uses imaging guidance to direct injection of contrast material into the center of one or more spinal discs to help identify the source of back pain. It is also used to help guide the treatment of abnormal intervertebral discs - sponge-like cushions located between the vertebrae of the spine.
CT Lung Screening
In lung cancer screening, individuals who have a high risk of developing lung cancer but show no signs or symptoms of the disease, undergo low-dose computed tomography (LDCT) scanning of the chest.
CT- Dual Energy
Bone Density Scan, DEXA Scan
This exam is used to measure bone mineral density (BMD). It is most commonly performed using dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry. The amount of x-rays absorbed by tissues and bone is measured by the DXA machine which correlates with bone mineral density.
Venography is an x-ray examination that uses an injection of contrast material to show how blood flows through your veins. The doctor may use it to find blood clots, identify a vein for use in a bypass procedure or dialysis access, or to assess varicose veins before surgery.
Cystography is an imaging test that can help diagnose problems in the bladder.
A defibrillator is a device that gives a high energy electric shock to the heart of someone who is in cardiac arrest. This high energy shock is called defibrillation, and it's an essential part of trying to save the life of someone who's in cardiac arrest.
Bone Density Scan
A bone density scan uses low dose X-rays to see how dense (or strong) your bones are. You may also hear it called a DEXA scan. Bone density scans are often used to diagnose or assess your risk of osteoporosis, a health condition that weakens bones and makes them more likely to break. As well as being quick and painless, a bone density scan is more effective than normal X-rays in identifying low bone density.
Percutaneous Abscess Drainage
An abscess is an infected fluid collection within the body. Percutaneous abscess drainage uses imaging guidance to place a needle or catheter through the skin into the abscess to remove or drain the infected fluid. It offers faster recovery than open surgical drainage.
ECG is a diagnostic tool that is routinely used to assess the electrical and muscular functions of the heart.
ECHO - 2D with Bubble
During an echocardiogram, a technician uses a probe that emits high-frequency sound waves (ultrasound) that "echo" off the structures of your heart. The waves, which are translated into video images visible on a monitor, can reveal information about your heart's structure and function. A bubble study gives additional information, as it can identify potential blood flow issues inside your heart.
Echo - Fetal
Fetal echocardiography (echo) uses sound waves to check the heart of your developing baby. Fetal echo can help find heart defects before birth.
Echo - TEE
A type of echo that uses a long, thin, tube (endoscope) to guide the ultrasound transducer down the esophagus ("food pipe" that goes from the mouth to the stomach). This lets the doctor see pictures of the heart without the ribs or lungs getting in the way. A TEE is done when your doctor needs a closer look at your heart or does not get the information needed from a regular echo.
Echo - TTE
During a transthoracic echocardiogram (TTE), a technician obtains views of the heart by moving a small instrument called a transducer to different locations on the chest or abdominal wall. A transducer, which resembles a microphone, sends sound waves into the chest and picks up echoes that reflect off different parts of the heart.
Stress echocardiography is a test that uses ultrasound imaging to show how well your heart muscle is working to pump blood to your body. It is most often used to detect a decrease in blood flow to the heart from narrowing in the coronary arteries.
An echocardiogram uses sound waves to produce images of your heart. This common test allows your doctor to see your heart beating and pumping blood. Your doctor can use the images from an echocardiogram to identify heart disease.
An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time, even when you're asleep. This activity shows up as wavy lines on an EEG recording.
EEG - Ambulatory
A safe, painless test, which records the electrical activity produced by your brain. An Amb EEG uses a digital recording system to record brain activity for 24-72 hours while you go about your daily routine.
An EKG/ECG test measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or "wave") travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on the ECG will show the timing of the top and lower chambers.
A diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.
Enteroclysis is an examination of the small bowel.
Computed tomography (CT) enterography uses special x-ray equipment and an injection of contrast material after the ingestion of liquid to produce detailed images of the small intestine and structures within the abdomen and pelvis. It's often used to identify and locate problems within the bowel, such as inflammation, bleeding, obstructions and Crohn's disease.
This exam is performed to assess frequent heartburn (pain), gastric reflux (food/acid coming back up), aspiration (food or fluid in your windpipe), difficulty eating, drinking, or swallowing.
Fluoroscopy is a type of medical imaging that shows a continuous X-ray image on a monitor, much like an X-ray movie. During a fluoroscopy procedure, an X-ray beam is passed through the body. The image is transmitted to a monitor so the movement of a body part or of an instrument or contrast agent ("X-ray dye") through the body can be seen in detail.
Pulmonary Function Tests
Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders.
Graded Exercise Test
Graded exercise testing (GXT) is the most widely used assessment to examine the dynamic relationship between exercise and integrated physiological systems. The information from GXT can be applied across the spectrum of sports performance, occupational safety screening, research, and clinical diagnostics.
A hip injection is a shot of medicine into the hip joint. The medicine can help relieve pain and inflammation. It can also help diagnose the source of hip pain.
A Holter monitor is a small, wearable device that keeps track of your heart rhythm. Your doctor may want you to wear a Holter monitor for one to two days. During that time, the device records all of your heartbeats.
HSG is a procedure that uses an X-ray to look at your fallopian tubes and uterus. It usually takes less than 5 minutes and you can go home the same day.
Saline implants are filled with sterile saltwater. They're inserted empty and then filled once they're in place. Saline breast implants are available to women age 18 and older for breast augmentation and to women of any age for breast reconstruction.
Silicone implants are pre-filled with silicone gel — a thick, sticky fluid that closely mimics the feel of human fat. Most women believe that silicone breast implants look and feel more like natural breast tissue. Silicone breast implants are available to women age 22 and older for breast augmentation and to women of any age for breast reconstruction.
Not treatable or remediable by surgery.
A hospital patient who receives lodging and food as well as treatment.
Intravenous pyelogram (IVP) is an x-ray exam that uses an injection of contrast material to evaluate your kidneys, ureters and bladder and help diagnose blood in the urine or pain in your side or lower back. An IVP may provide enough information to allow your doctor to treat you with medication and avoid surgery.
Joint injections are used to deliver steroids directly into a joint, such as a knee, ankle, or wrist. Sometimes fluid is removed from the joint before the steroid is injected.
When a medical professional refers to your lower extremity, they're typically referring to everything between your hip to your toes.
A lumbar puncture (spinal tap) is performed in your lower back, in the lumbar region. During a lumbar puncture, a needle is inserted between two lumbar bones (vertebrae) to remove a sample of cerebrospinal fluid. This is the fluid that surrounds your brain and spinal cord to protect them from injury.
A lung biopsy is a procedure in which samples of lung tissue are removed (with a special biopsy needle or during surgery) to determine if lung disease or cancer is present.
It is the amount of air that can be inhaled or exhaled during one respiratory cycle. This depicts the functions of the respiratory centers, respiratory muscles and the mechanics of the lung and chest wall.
Lymphoscintigraphy helps evaluate your body's lymphatic system for disease using small amounts of radioactive materials called radiotracers that are typically injected into the bloodstream, inhaled, swallowed, or in the case of lymphoscintigraphy, injected into the skin.
A diagnostic mammogram can help determine if these symptoms are indicative of the presence of cancer. As compared to screening mammograms, diagnostic mammograms provide a more detailed x-ray of the breast using specialized techniques. They are also used in special circumstances, such as for patients with breast implants.
Screening mammography is a specific type of breast imaging that uses low-dose x-rays to detect cancer early - before women experience symptoms - when it is most treatable.
Breast ultrasound uses sound waves to make images of the breast. Ultrasound images may be called sonograms. Breast ultrasound is a non-invasive test. It's often used as a follow-up test after an abnormal finding on a mammogram, breast MRI or clinical breast exam.
A mammogram is an X-ray image of your breasts used to screen for breast cancer. During a mammogram, your breasts are compressed between two firm surfaces to spread out the breast tissue. Then an X-ray captures black-and-white images of your breasts that are displayed on a computer screen and examined by a doctor who looks for signs of cancer.
This test is performed to evaluate how "reactive" or "responsive" your lungs are to things in the environment. It can help your doctor evaluate symptoms suggestive of asthma, such as cough, chest tightness and shortness of breath, and help diagnose whether or not you have asthma.

Functional Magnetic Resonance Imaging
Measures the small changes in blood flow that occur with brain activity. It may be used to examine the brain's functional anatomy, (determine which parts of the brain are handling critical functions), evaluate the effects of stroke or other disease, or to guide brain treatment. fMRI may detect abnormalities within the brain that cannot be found with other imaging techniques.
MRI - Prostate
Uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the structures within a man's prostate gland. It is primarily used to evaluate the extent of prostate cancer and determine whether it has spread. It also may be used to help diagnose infection, an enlarged prostate or congenital abnormalities.
Magnetic Resonance Venography
A diagnostic procedure that uses a combination of a large magnet, radio frequencies, and a computer to produce detailed images of organs and structures within the body. An MRV uses magnetic resonance technology and intravenous (IV) contrast dye to visualize the veins. Contrast dye causes the blood vessels to appear opaque on the X-ray image, allowing the physician to visualize the blood vessels being evaluated. MRV is useful in some cases because it can help detect causes of leg pain other than vein problems.
Myelography uses a real-time form of x-ray called fluoroscopy and an injection of contrast material to evaluate the spinal cord, nerve roots and spinal lining (meninges). It is particularly useful for assessing the spine following surgery and for assessing disc abnormalities in patients who cannot undergo MRI.
Myocardial ischemia occurs when blood flow to your heart is reduced, preventing the heart muscle from receiving enough oxygen. The reduced blood flow is usually the result of a partial or complete blockage of your heart's arteries (coronary arteries).
A neurological exam checks for disorders of the central nervous system. The central nervous system is made of your brain, spinal cord, and nerves from these areas. It controls and coordinates everything you do, including muscle movement, organ function, and even complex thinking and planning.
NM - Bone Imaging Whole Body

NM - Hepatobiliary Imaging w CCK (HIDA)
Hepatobiliary Iminodiacetic Acid
For a HIDA scan, also known as cholescintigraphy and hepatobiliary scintigraphy, a radioactive tracer is injected into a vein in your arm. The tracer travels through your bloodstream to your liver, where the bile-producing cells take it up. The tracer then travels with the bile into your gallbladder and through your bile ducts to your small intestine.
NM - Injection Sentinel Nodes with out Imaging
Sentinel node biopsy is a surgical procedure doctors use to see whether early-stage breast cancer has spread beyond the tumor and into the lymphatic system.
NM - Kidney Flow and Function Single

Incapable of walking.
Nuclear medicine imaging uses small amounts of radioactive materials called radiotracers that are typically injected into the bloodstream, inhaled or swallowed. The radiotracer travels through the area being examined and gives off energy in the form of gamma rays which are detected by a special camera and a computer to create images of the inside of your body. Nuclear medicine imaging provides unique information that often cannot be obtained using other imaging procedures and offers the potential to identify disease in its earliest stages.
Nuclear Medicine Stress Test
A nuclear stress test uses radioactive dye and an imaging machine to create pictures showing the blood flow to your heart. The test measures blood flow while you are at rest and are exerting yourself, showing areas with poor blood flow or damage in your heart. The test usually involves injecting radioactive dye, then taking two sets of images of your heart — one while you're at rest and another after exertion.
Obstetric ultrasound uses sound waves to produce pictures of a baby (embryo or fetus) within a pregnant woman, as well as the mother's uterus and ovaries. It does not use ionizing radiation, has no known harmful effects, and is the preferred method for monitoring pregnant women and their unborn babies. A Doppler ultrasound study - a technique that evaluates blood flow in the umbilical cord, fetus or placenta - may be part of this exam.

Your radiologist is a medical doctor who specializes in diagnosing and treating disease and injury, using medical imaging techniques such as x-rays, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, positron emission tomography (PET), fusion imaging, and ultrasound. Because some of these imaging techniques involve the use of radiation and require training to understand radiation safety and protection.
Sentinel Node Injections (NM)
Sentinel node biopsy is a surgical procedure used to determine whether cancer has spread beyond a primary tumor into your lymphatic system. It's used most commonly in evaluating breast cancer and melanoma.
Small Bowel Follow
Small bowel follow-through uses a form of real-time x-ray called fluoroscopy and a barium-based contrast material to produce images of the small intestine. It is safe, noninvasive and may be used to help accurately diagnose bowel disease, obstructions, polyps, cancer, and other symptoms.
Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale. Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing. Spirometry may also be used periodically to monitor your lung condition and check whether a treatment for a chronic lung condition is helping you breathe better.
Stents are small, expandable tubes that treat narrowed arteries in your body. In people with coronary heart disease caused by the buildup of plaque.
A Spinal Cord Stimulator (SCS)
A spinal cord stimulator (SCS) device is surgically placed under your skin and sends a mild electric current to your spinal cord (Fig. 1). Thin wires carry current from a pulse generator to the nerve fibers of the spinal cord. When turned on, the SCS stimulates the nerves in the area where your pain is felt. Pain is reduced because the electrical pulses modify and mask the pain signal from reaching your brain.
A stress echocardiography, also called an echocardiography stress test or stress echo, is a procedure that determines how well your heart and blood vessels are working.
Stress Echo - Bicycle
A bicycle stress echocardiogram is a test performed to evaluate your heart. The test involves an echocardiogram, (ultrasound of your heart), an electrocardiogram (ECG) and a supine bicycle attached to a bed. The supine bike allows the patient to pedal (exercise) while lying flat on the bed. This allows the echocardiogram to be performed.
Stress Echo - Dobutamine
A dobutamine stress echocardiogram (DSE) may be used if you are unable to exercise. Dobutamine is put in a vein and causes the heart to beat faster. It mimics the effects of exercise on the heart.

This test tells how much air moves in and out of your lungs when you exercise. During the test, you may be asked to walk on a treadmill or ride on a stationary bike. The test may show exactly where your breathing problems begin. They may begin in your lungs, your heart, or both. Your test results can also show a safe activity level for you.
Symptomatic can mean showing symptoms, or it may concern a specific symptom. Symptoms are signs of disease or injury. They are noticed by the person.
Transesophageal echocardiography (TEE) is a test that produces pictures of your heart. TEE uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it. Unlike a standard echocardiogram, the echo transducer that produces the sound waves for TEE is attached to a thin tube that passes through your mouth, down your throat and into your esophagus. Because the esophagus is so close to the upper chambers of the heart, very clear images of those heart structures and valves can be obtained.
Thallium Nuclear Scan
A thallium stress test is a nuclear imaging test that shows how well blood flows into your heart while you're exercising or at rest. This test is also called a cardiac or nuclear stress test.
Thyroid Needle Aspiration
A thallium stress test is a nuclear imaging test that shows how well blood flows into your heart while you're exercising or at rest. This test is also called a cardiac or nuclear stress test.
Transjugular Intrahepatic Portosystemic Shunts
TIPS is a procedure that uses imaging guidance to connect the portal vein to the hepatic vein in the liver. A small metal device called a stent is placed to keep the connection open and allow it to bring blood draining from the bowel back to the heart while avoiding the liver. TIPS may successfully reduce internal bleeding in the stomach and esophagus in patients with cirrhosis and may also reduce the accumulation of fluid in the abdomen (ascites).
Ultrasound imaging uses sound waves to produce pictures of the inside of the body. It is used to help diagnose the causes of pain, swelling, and infection in the body's internal organs and to examine a baby in pregnant women and the brain and hips in infants. It's also used to help guide biopsies, diagnose heart conditions, and assess damage after a heart attack. Ultrasound is safe, noninvasive, and does not use ionizing radiation.
"Upper extremity" is a term used to define the upper limb.
Upper Gastrointestinal Tract
Upper gastrointestinal tract radiography or upper GI uses a form of real-time x-ray called fluoroscopy and a barium-based contrast material to produce images of the esophagus, stomach, and small intestine. It is safe, noninvasive, and may be used to help accurately diagnose pain, acid reflux, blood in the stool and other symptoms.
A diagnostic procedure performed most commonly in male patients to diagnose urethral pathologies such as trauma to the urethra or urethral stricture.
Urinary system — your kidneys, ureters, bladder, and urethra.
Urography uses imaging and contrast material to evaluate or detect blood in urine, kidney or bladder stones, and cancer in the urinary tract. Urography with conventional x-ray is known as intravenous pyelogram (IVP). Urography is also often performed using a computed tomography (CT) or magnetic resonance imaging (MRI). CT and MR urography is painless and proven effective in detecting urinary tract issues.
Carotid (kuh-ROT-id) ultrasound is a safe, painless procedure that uses sound waves to examine the blood flow through the carotid arteries.
US Guided Biopsies
An ultrasound-guided breast biopsy uses sound waves to help locate a lump or abnormality and remove a tissue sample for examination under a microscope. It is less invasive than surgical biopsy, leaves little to no scarring and does not involve exposure to ionizing radiation.
This procedure is performed to create a "map" of your leg veins for the surgeon in preparation for various procedures that will include bypass graft surgery (replacing diseased vessels in your body with the healthy vein from your leg).
Venography is an x-ray examination that uses an injection of contrast material to show how blood flows through your veins. Your doctor may use it to find blood clots, identify a vein for use in a bypass procedure or dialysis access, or to assess varicose veins before surgery.
Venous ultrasound uses sound waves to produce images of the veins in the body. It is commonly used to search for blood clots, especially in the veins of the leg - a condition often referred to as deep vein thrombosis. Ultrasound does not use ionizing radiation and has no known harmful effects.
Venous duplex scan is a painless exam that uses high-frequency sound waves (ultrasound) to capture images of internal views of veins that return blood to the heart. During an upper extremity venous duplex scan, the veins in your neck, shoulders, arms, and wrists are viewed. During a lower extremity venous duplex scan, the veins in the legs and ankles are viewed.
A machine designed to provide mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently.
X-rays are a type of radiation called electromagnetic waves. X-ray imaging creates pictures of the inside of your body.
An imaging test that combines multiple breast X-rays to create a three-dimensional picture of the breast.
Ultrasound test to see how blood moves through your arteries & veins. Duplex ultrasound combines traditional ultrasound (uses sound waves that bounce off blood vessels to create pictures) and Doppler ultrasound (records sound waves reflecting off moving objects such as blood, to measure their speed and other aspects of how they flow). Examples include Arterial and venous duplex ultrasound of abdomen to look at blood vessels and blood flow in the abdominal area. Carotid duplex ultrasound looks at the carotid artery in the neck. Duplex ultrasound of extremities looks at the arms or legs. Renal duplex ultrasound examines kidneys and their blood vessels.
In radiology refers to form of imaging e.g. CT, US, MRI, etc.
Nothing by mouth is a medical instruction meaning to withhold food and fluids. It is also known as nil per os (npo or NPO), a Latin phrase.
Upper GI Exam
Upper gastrointestinal tract radiography or upper GI uses a form of real-time x-ray called fluoroscopy and a barium-based contrast material to produce images of the esophagus, stomach and small intestine. It is safe, noninvasive, and may be used to help accurately diagnose pain, acid reflux, blood in the stool and other symptoms.
Vascular Access, Venous Catheter
Venous access is any method used to access the bloodstream through the veins, either to administer intravenous therapy (e.g. medication, fluid), parenteral nutrition, to obtain blood for analysis, or to provide an access point for blood-based treatments such as dialysis or aphaeresis.
1.5T vs 3T MRI
The "T" in 1.5T and 3T stands for Tesla. Tesla is defined as the unit of measurement used to describe the strength of the magnet used in an MRI. The magnet is the M in MRI (Magnetic Resonance Imaging). This magnet is the basis of how images in MRI are acquired. 3T MRI has a stronger magnet and makes better images of organs and soft tissue than other types of MRI do. It is used to make images of the brain, the spine, the soft tissue of joints, and the inside of bones and blood vessels.
