Cta

CTA or computed tomography angiography is a regular CT scan with added dyes to picture the body's blood vessels. These dyes are known as contrasts that are injected intravenously. CTA is used for diagnosing blocks in vessels, stenosis, aneurysms, and dissections. It is also used to view the body's major blood vessels like the aorta, renal artery, pulmonary artery, carotid artery, etc. CTA of an intracranial artery can reveal a clot location in stroke.
