CT Angiogram (CTA)

Computed Tomography Angiography (CTA) uses computed tomography (CT) technology to visualize blood flow in arterial vessels throughout the body, from arteries serving the brain to those bringing blood to the lungs, kidneys, arms and legs. CTA is used to screen people for arterial disease, such as an aneurysm or pulmonary embolism. The procedure is minimally invasive, and most patients can have a CTA without being admitted to the hospital.
