{wiki=CT_pulmonary_angiogram}
A CT pulmonary angiogram (CTPA) is a specialized imaging test that uses computed tomography (CT) to visualize the blood vessels in the lungs, particularly the pulmonary arteries. This test is primarily used to diagnose conditions such as pulmonary embolism (PE), which is a blockage in one of the pulmonary arteries usually caused by blood clots that travel to the lungs from the deep veins of the legs or other parts of the body.
