Medical Terminology - Chapter 20
Movement away from the midline of the body.
Movement toward the midline of the body.
X-ray image of blood vessels after injecting contrast material into the vessels.
In this AP x-ray view, x-rays travel from an anteriorly placed source to a posteriorly placed detector (x-ray beam passes from the front to the back of the body).
Process of x-ray imaging a joint after injecting contrast into the joint.
A radioactive (technetium-99m) phosphate compound is injected intravenously and bones are scanned for evidence of tumors.
Process of x-ray imaging bile ducts after injecting contrast into the bile ducts.
Use of motion picture techniques to record a series of x-ray images.
Use of x-ray equipment and a computer to create multiple views of organs, including cross-sectional or axial images.
Material (contrast media) is injected into vessels and organs to obtain contrast with surrounding tissues when viewed on x-ray and other images.
Sound waves are used to image the structure of the heart.
Lengthening or straightening a flexed limb.
Bending a part of the body.
Emission of glowing light that results from exposure to and absorption of radiation from x-rays.
Process of using x-rays to produce an image on a fluorescent screen.
Radioisotope (gallium 67) is injected intravenously and has an affinity for tumors and other lesions.
Machine to detect gamma rays given off by radiopharmaceuticals (radioactive compounds) during scanning for diagnostic purposes.
High-energy rays emitted by radioactive substances in tracer studies.
Time required for a radioactive substance to lose half its radioactivity by disintegration.
X-ray record of the endometrial cavity and fallopian tubes is obtained after injection of contrast material through the vagina and into the endocervical canal.
Saline solution is injected through a catheter inserted through the vagina and into the endocervical canal to distend the uterine cavity, which is then examined by ultrasound.
Therapeutic procedures performed by a radiologist.
In vitro, In vivo
Process, test, or procedure performed, measured, or observed outside a living organism.
Transformation of electrically neutral substances into electrically charged particles.
Combination of a radioactive substance (radionuclide) and a drug; used in nuclear medicine studies.
Lying down on one's side with the x-ray beam horizontally positioned.
Magnetic resonance imaging
Magnetic field and radio waves produce sagittal, coronal, and axial images of the body; especially effective to image soft tissues.
X-ray image of the spinal cord after injection of contrast into the membranes surrounding the spinal cord.
Medical specialty that studies the uses of radioactive substances (radionuclides and radiopharmaceuticals) in the diagnosis of disease.
Positioned at an angle; an x-ray view.
Radionuclides given intravenously emit positrons, which
create a cross-sectional image of cellular metabolism in specialized areas of the body.
In this position, x-ray beams pass from the back to the front of the body.
Lying on the belly (face down).
X-ray record of the kidneys (renal pelvis) and urinary tract after contrast is injected (intravenously or retrograde).
Aids physicians in administering diagnostic x-ray procedures.
Medical specialty concerned with the use of x-rays for the diagnosis and treatment of disease.
Test combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient's blood.
Radioactive form of an element; radionuclide.
Permitting the passage of x-rays.
Radioactive form of an element; gives off energy in the form of radiation; radioisotope.
Obstructing the passage of x-rays.
Radioactive drug (radionuclide plus a drug) that is administered safely for diagnostic and therapeutic purposes.
Lying down (prone or supine).
Study of x-rays; radiology.
Image of an area, organ, or tissue of the body obtained from ultrasound, radioactive tracer studies, or computed tomography.
Single photon emission
Radioactive tracer is injected intravenously, and a computer computed tomography reconstructs a three-dimensional image based on a (SPECT) composite of many views.
Image of sound waves as they bounce off organs in the body; echogram or ultrasound image.
Lying on one's back.
Attaching a radionuclide to a chemical allowing its path in the body.
Thallium 201 is injected intravenously to allow for myocardial perfusion and assess damage to heart muscle from heart attacks.
Technetium Tc 99m
A nuclear medicine study in which a radiopharmaceutical sestamibi scan (Tc 99m sestamibi) is injected intravenously and traced to heart muscle to observe heart function.
Pertaining to treatment or therapy.
An iodine 131 radionuclide is administered intravenously, and an image of the size and shape of the thyroid gland is obtained by scanning.
Process of taking a series of images to show an organ in layers or depth.
Radionuclides are attached to chemicals, used as tags or markers, and followed as they travel through the body.
Handheld device that sends and receives ultrasound signals.
Diagnostic technique that projects and retrieves high-frequency sound waves as they bounce (echo) off parts of the body.
Rate of absorption of a radionuclide into an organ or tissue.
Process of taking x-ray images of the urinary tract after injecting contrast.
Radiopharmaceutical is inhaled (ventilation study) and injected intravenously (perfusion study) followed by imaging its passage through the respiratory tract.
