CT Angio - Upper Limb
What is CT Angio - Upper Limb?
A CT (Computed Tomography) Upper Limb is an imaging technique used to get detailed images of the arteries that carry blood to the upper limbs (hands). This procedure detects narrowed or blocked arteries of the wrist, arm, upper arm, and shoulder. It helps determine peripheral artery disease and Buerger’s disease, caused by swollen blood vessels that lead to blood clots. It helps examine any deposition of fat or cholesterol in the artery walls.
For this, a contrast dye is injected into the veins. Then, the rotating beams of X-Rays capture a clear image of the area which is then analyzed on the monitor. It is a highly accurate and painless procedure. However, pregnant women should inform the doctor about their condition to avoid radiation exposure to the baby.
