X-rays of the blood vessels using a dye.
Radiographic technique for imaging blood vessels. In classic methods, the vessels of the brain are visualized by injection of radiopaque dye. Digital subtraction angiography (using computer processing to produce images) carries less risk for the patient because the amount of dye can be reduced. Magnetic resonance angiography is a newer, noninvasive technique that is helpful for visualizing extracranial and large intracranial vessles. However, at present, invasive angiograpy is more sensitive for smaller vessels.
a technique that uses dye to highlight blood vessels.
special type of x-ray used to look at blood flow.
An X-ray technique that makes use of a dye injected into the coronary arteries to study blood circulation through those vessels. The test allows physicians to measure the degrees of obstruction to blood flow. (Circulation through an artery is not seriously reduced until the inside diameter of the vessel is more than 75 percent obstructed.)
An X-ray examination of your blood vessels and lymphatics, after the injection of dye.
A radiographic technique where a substance is injected into a blood vessel for the purpose of identifying its anatomy by X-ray.

An internal x-ray of the heart and blood vessels which may be taken at the time of cardiac catheterisation (see below). In particular this test assesses the coronary arteries (the blood vessels which supply the heart muscle).
part of an angiogram procedure in which cardiologists inject a dye into the body through a thin, flexible tube called a catheter, inserted into an artery. The dye shows up on X-rays to reveal abnormalities of blood flow and narrowing of coronary arteries. Requires a local anesthetic and post-procedure rest to allow the insertion opening to close.
Radiography of blood vessels using the injection of material opaque to x-rays to give better definition to the vessels.
A procedure that yields X-ray pictures of the inside of blood vessels. During angiography, a long slender tube called a catheter is inserted into a large artery (generally in the groin or arm). The catheter is slowly and carefully threaded through the artery until its tip reaches the segment of vessel to be examined. A small amount of dye is injected into the blood vessel through the catheter, and X-rays are taken. The dye enables the blood vessels to appear on the X-ray pictures.
