Who does angiography?

Cards or vascular: Angio refers to vessel so could be any vessel, but most frequently refers to coronary (heart) vessels, therefore cardiologist usually performs. Other common vessels include aortic and femoral / iliac vessels, carotids, renal arteries and mesenteric vessels. These vessels are often imaged by interventional radiologists or vascular surgeons.

Angio means Blood: Angio = blood, gram = picture; thus angiograms are pictures which show a 2d image, still or motion, of dye added into the blood, so that the dye/blood column shows on x-ray. Without the dye, the blood looks same on x-ray as surrounding tissues. Procedures commonly done by cardiologists (such as i), radiologists or, sometimes, vascular surgeons. Also by ophthalmologists for the vessels of the eye.
