CT Angiography Right Lower Limb
What is CT Angiography Right Lower Limb?
CT angiography of the right lower limb (leg) is a safe, robust, and quick medical test to evaluate the right leg’s blood vessels (arteries and veins) in patients with peripheral artery disease (PAD). It is widely used to assess peripheral arterial bypass grafts and associated complications in the right leg.
A computed tomography (CT) angiogram uses X-rays to show a detailed picture of the blood vessels and tissues, with the application of a special dye (usually iodine solution). The dye is injected intravenously before or during the procedure to highlight the blocked or narrowed areas of the blood vessels. This test is performed in a hospital under the direct supervision of a doctor. You should inform your doctor if you are allergic to iodine.
Why is CT Angiography Right Lower Limb done?
- To diagnose narrowed blood vessel or blocked arteries of the pelvis, knees, legs, ankles and injured blood vessels
- To detect any peripheral artery disease (PAD) which results in narrowed or blockage in the peripheral arteries of your leg (claudication)
- To find out takayasu’s disease (aorta inflammation which carries blood from the heart to the remaining body) and buerger’s disease (rare problem of swollen arm or leg arteries / vein which leads to clot)
- To evaluate atherosclerosis (depositions of fats or cholesterol in the artery walls) and vasculitis (swollen artery which results in decreased blood flow)
