Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography—the visualization of arteries and veins—throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls ...
Computed tomography angiography (CTA) is a type of contrast CT to visualize the arteries and veins throughout the body.

An example of this type of exam is CT pulmonary angiogram (CTPA) used to diagnose pulmonary embolism (PE).
