angiography

Vascular X-ray procedure

Angiography is a medical imaging technique that visualizes blood vessels.

A contrast dye is injected into the bloodstream, making arteries and veins visible on X-rays.

Doctors use angiography to detect blockages, aneurysms, and other vascular abnormalities: The angiography revealed a narrowed coronary artery.

Coronary angiography examines heart vessels; cerebral angiography images the brain's blood supply.
