detects aneurysms. Iodine-rich contrast material (dye) injected. injury, aneurysms.
blockages, disorganized blood vessels and blood supply to tumors, congenital (birth related) abnormalities of the heart, blood vessels or various parts of the body which might be supplied by abnormal blood vessels
identify abnormalities, such as aneurysms, in the aorta, both in the chest and abdomen.
detect atherosclerotic disease in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke.
identify a small aneurysm or arteriovenous malformation (abnormal communications between blood vessels) inside the brain or other parts of the body.
detect atherosclerotic disease that has narrowed the arteries to the legs, prepare for endovascular intervention or surgery.
detect disease in the arteries to the kidneys or visualize blood flow to help prepare for a kidney transplant.
guide interventional radiologists and surgeons making repairs to diseased blood vessels, such as implanting stents or evaluating a stent after implantation.
detect injury to one or more arteries in the neck, chest, abdomen, pelvis or extremities in patients after trauma.
evaluate arteries feeding a tumor prior to surgery or other procedures such as chemoembolization or selective internal radiation therapy.
show the extent and severity of the effects of coronary artery disease.
examine pulmonary arteries in the lungs to detect pulmonary embolism (blood clots, such as those traveling from leg veins) or pulmonary arteriovenous malformations.
look at congenital abnormalities in blood vessels, especially arteries in children (e.g., malformations in the heart or other blood vessels due to congenital heart disease).
evaluate obstructions of vessels.
brain lesions, tumors, abscesses. detects abnormalities in the brain waves or electrical activity of the brain. electrodes detect tiny electrical charges that result from the activity of the brain cells. These studies are used to measure electrical activity in the brain in response to stimulation of sight, sound, or touch.
test functioning of spinal nerves. Absence of the reflex may be caused by damage to the muscle, peripheral nerve, nerve roots, or spinal cord at that level. A hyperactive reflex may indicate disease of the pyramidal tract above the level of the reflex arc being tested. Generalized hyperactivity of DTRs may be caused by hyperthyroidism.
