Computerized tomography angiography (CTA)

Computed tomography angiography (CTA) is an examination that uses X-rays to visualize blood flow in arterial and venous vessels throughout the body, from arteries serving the brain to those bringing blood to the lungs, kidneys and arms and legs. CT combines the use of X-rays with computerized analysis of the images. Beams of X-rays are passed from a rotating device through the patient's body from several angles to provide cross-sectional images, which are electronically assembled into a three-dimensional picture. The CTA is a much less invasive and more patient-friendly procedure than catheter angiography because it uses contrast material in place of a sizable catheter.
