CT
Computerized Tomography
CT (computed tomography) produces clearly defined three-dimensional images of all body systems -- including organs, bones, arteries and veins -- in a matter of seconds! Using high speed x-rays that rotate in continuous 360-degree motion around the patient, incredibly detailed laser images of cross-sectional slices of the body are created on a computer screen. Tissue abnormalities, tumor masses, tiny fractures, displaced bones, and unusual accumulations of fluid may be detected so that physicians can pinpoint exact areas for treatment
CT, sometimes called CAT scan, provides more detailed information on many types of diseases or trauma than plain x-ray. IV (intravenous) contrast is often used to help find tumors, cancers, pneumonia and many other diseases.
Did
you know many angiography studies can now be done with CT? These exams
are called CT Angiograms or CTAs.
During a normal arteriogram, a wire called a catheter is inserted into the artery, typically in your groin, and then guided to the proper location and x-ray contrast is injected into the main arteries that go to the kidneys. This is done to look for narrowing of the arteries that supply the kidneys with blood. This can NOW be done with CT, and requires NO CATHETERS, and can be performed just the same, and as quickly, as any other CT. Before you have an arteriogram, ask your doctor is a CTA would be beneficial to you.
