CT - RENAL ANGIO How does CT work? CT uses X-rays to perform its work. These X-rays come from an X-ray tube which is placed inside a square machine called the gantry. The part of your body to be scanned goes inside a hole in this gantry. Why is CT such a good modality? Ordinary X-ray pictures are one-dimensional representations of body parts but CT allows us to section the body to view its inner parts. Thus, the skull X-ray only shows us the outer part, whereas CT shows us the inner parts of the brain. Where is CT useful? All parts of the body can be scanned with CT. For each part, there are specific indications or reasons for scanning. Your referring doctor and the consultant radiologist are the best judges of the usefulness of CT scanning in a specific situation and areas. Are there any dangers of CT scanning? Though X-rays involve radiation, there are no dangers, in practice. In women who are pregnant, however, CT scanning should be done after weighing all the risks. What is the injection that I may receive? Majority of the patients will be injected with a "dye" which enhances the ability of CT scans to pick up abnormalities. This is routine. The dye used is a non-ionic contrast medium, which is much safer than the routine, cheaper, ionic dyes. Are there any complications because of the "dye"? 0.5% of patients may get nausea and redness of the skin. Though severe reactions are known, these are very rare and uncommon.

Why is CT - RENAL ANGIO ?

CT Renal Angiogram is an imaging test to look at the blood vessels in your kidneys. Your healthcare provider can use it to look at the ballooning of a blood vessel (aneurysm), narrowing of a blood vessel (stenosis) or blockages in a blood vessel. He or she can also see how well blood is flowing to your kidneys. For the test, the radiologist injects a CONTRAST dye into the artery that brings blood into the kidney. Then he or she uses X-ray images to watch the dye as it flows through the blood vessels in the kidneys. X-rays use a small amount of radiation to create images of your bones and internal organs. A renal angiogram is one type of X-ray. Fluoroscopy is used during a renal angiogram. Fluoroscopy is a kind of X-ray movie.
