CT angiogram for lung cancer

CT angiogram for lung cancer

Your radiologist may perform a CT angiogram if you are experiencing shortness of breath to check for blood clots or other blockages in the lungs.

What is a CT angiogram?

A CT angiogram allows doctors to examine the pulmonary artery, which is the main artery that supplies blood to the lungs from the heart. In this test, a special iodine-based contrast material is injected into the body before a CT scan to illuminate the pulmonary artery and smaller blood vessels in the chest.
