Angiography - Definition

February 2017


Definition


An angiography allows us to obtain images of the blood vessels that are not visible on a simple x-ray. A contrast agent, generally iodine in the absence of an allergy, is injected into the blood to bring out the network of vessels, then the patient is x-rayed. An angiography allows us to diagnose abnormalities in the arteries such as stenoses or aneurysms. It also enables intervention in the vessels to eliminate the abnormality: an interventional angiography or angioplasty is then used. The patient, under local anesthesia, is generally conscious during the procedure. The most well-known angiography is the coronarography that explores the blood vessels in the heart.
