A procedure performed to view blood vessels after injecting them with a radioopaque dye that outlines them on x-ray. This technique can be usefully used to look at arteries in many areas of the body, including the brain, neck (carotids), heart, aorta, chest, pulmonary circuit, kidneys, gastrointestinal tract, and limbs.

The most accurate method (the "gold standard") for evaluating and defining coronary artery disease (CAD). Coronary angiography is used to identify the exact location and severity of CAD. During coronary angiography, a small catheter (a thin hollow tube with a diameter of 2-3 mm) is inserted through the skin into an artery in the groin or [..]

A test to examine blood vessels in the retina, choroid, and iris of the eye. A special dye is injected into a vein in the arm and pictures are taken as the dye passes through the blood vessels in the eye. The dye is injected into a vein in the arm. The pictures taken as the dye passes through the blood vessels in the eye can help detect a number of [..]

A procedure to x-ray blood vessels. The blood vessels can be seen because of an injection of a dye that shows up in the x-ray.

1731, from angio- + -graphy.

Angiography is a way of looking at the blood vessels either to identify blockages, inflammation or other abnormalities. There are many ways of performing angiography. Ultrasound can be used to look at [..]

Radiography of blood vessels using the injection of material opaque to x-rays to give better definition to the vessels.

n the viewing via radiography of potentially blocked areas in the circulatory system. Commonly used to diagnose blood clots, aneurysms, and tumors - as well as the extent to which vessels leading to t [..]

A brain-imaging technique in which a specialized X-ray image of the head is taken shortly after the cerebral blood vessels have been filled with a radiopaque dye by means of a catheter. This technique allows visualization of the major blood vessels and is used to assess stroke risk and other conditions.

Radiography of blood vessels using the injection of material opaque to x-rays to give better definition to the vessels.

(n) roentgenographic examination of blood vessels after injection of a radiopaque contrast medium; produces an angiogram

A test that shows how blood moves through the blood vessels and heart. It uses x-rays and the injection of a fluid called a contrast agent that can be seen on the x-rays.

X-ray that uses dye injected into arteries so that blood circulation can be studied.

A method of following and recording the blood supply of a given organ by x-ray recordng of a radio-opaque dye injected into an artery.

a medical imaging technique used to visualize the inside of blood vessels or organs, with particular interest in the arteries, veins, and the chambers of the heart.

imaging of the coronary arteries used to identify the location and severity of any obstructions. Coronary angiography typically involves the administration of a contrast medium and imaging of the coro [..]

Radiography of Blood Vessels after injection of a contrast medium.

Radiography of the vascular system of the Brain after injection of a contrast medium.

Radiography of the vascular system of the Heart Muscle after injection of a contrast medium.

A method of delineating Blood Vessels by subtracting a Tissue background image from an image of Tissue plus intravascular contrast material that attenuates the X-ray Photons. The background image is d [..]

Radionuclide Ventriculography where a bolus of radionuclide is injected and data are recorded from one pass through the Heart Ventricle. Left and Right Ventricular Function can be analyzed independent [..]

An imaging study that is used to evaluate patients for coronary artery disease. The procedure involves inserting a catheter into the body and threading it into the aorta.

A procedure to x-ray blood vessels. The blood vessels can be seen because of an injection of a dye that shows up in the x-ray.

Imaging of blood vessels using injected contrast material (dye) to better visualize the vessels. The word is derived from angio (blood vessels) and gram (record or picture). 

<investigation> A radiographic technique where a radio-opaque (shows up on X-ray) contrast material is injected into a blood vessel for the purpose of identifying its anatomy on X-ray. This technique is used to image arteries in the brain, heart, kidneys, gastrointestinal tract, aorta, neck (carotids), chest, limbs and pulmonary circuit. (27 [..]

A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitised image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of th [..]
