Is an imaging test that makes a detailed picture (called an angiogram) of blood vessels.
1. Angiography is the X-ray imaging of blood vessels using contrast agents injected into the bloodstream through a thin plastic tube (catheter) that is placed directly in the blood vessel. The images taken are called angiograms.  An angiogram is an X-ray test that uses a special dye and camera (fluoroscopy) to take pictures of the blood flow in an artery (such as the aorta) or a vein (such as the vena cava). An angiogram can be used to look at the arteries or veins in the head, arms, legs, chest, back, or belly. During an angiogram, a thin tube called a catheter is placed into a blood vessel in the groin (femoral artery or vein) or just above the elbow (brachial artery or vein). The catheter is guided to the area to be studied. Doctors use angiography to diagnose diseases and abnormalities of the blood vessels, including atherosclerosis, blood clots, aneurysm, and coronary artery disease. Your body has two types of blood vessels, the arteries and veins. When angiography examines arteries, the picture is called an arteriogram. Catheter angiography involves inserting a catheter into a blood vessel in your groin or elbow. The catheter wire is fed or guided to the appropriate area. X-rays are used to produce the angiogram (picture) of the vessel. Coronary angiography (an-jee-OG-rah-fee) is a test that uses dye and special x rays to show the insides of your coronary arteries. The coronary arteries supply oxygen-rich blood to your heart. A waxy substance called plaque (plak) can build up inside the coronary arteries.  Definition. Angiography is the x-ray study of the blood vessels. An angiogram uses a radiopaque substance, or dye, to make the blood vessels visible under x ray. Arteriography is a type of angiography that involves the study of the arteries. Angiography requires the injection of a contrast dye that makes the blood vessels visible to x ray. The dye is injected through a procedure known as arterial puncture. The puncture is usually made in the groin area, armpit, inside elbow, or neck. Unsourced material may be challenged and removed. (April 2014). Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. The film or image of the blood vessels is called an angiograph, or more commonly, an angiogram. Though the word itself can describe both an arteriogram and a venogram, in its everyday usage, the terms angiogram and arteriogram are often used synonymously, whereas the term venogram is used more precisely. This method is known as conventional or catheter angiogram. The angiogram pictures can be made into regular X-ray films or stored as digital pictures in a computer. An angiogram can find a bulge in a blood vessel (aneurysm). It can also show narrowing or a blockage in a blood vessel that affects blood flow. During an angiogram, a thin tube called a catheter is placed into a blood vessel in the groin (femoral artery or vein) or just above the elbow (brachial artery or vein). The catheter is guided to the area to be studied. Angiography is an imaging test that makes a detailed picture (called an angiogram) of blood vessels. Angiography makes images of arteries and veins in the abdomen, brain, heart, kidneys, lungs and legs. Angiography shows blood flow and blood vessels that are obstructed, blocked, narrowed, enlarged or malformed. Catheter angiography involves inserting a catheter into a blood vessel in your groin or elbow. The catheter wire is fed or guided to the appropriate area. X-rays are used to produce the angiogram (picture) of the vessel. Why It Is Done. An angiogram is done to: 1  Detect problems with blood vessels that affect blood flow. 2  Examples of such problems include a tear in a blood vessel (which can cause blockage or internal bleeding), aneurysms (which are weaknesses in the blood vessel wall), and narrowed areas. During an angiogram, a thin tube called a catheter is placed into a blood vessel in the groin (femoral artery or vein) or just above the elbow (brachial artery or vein). The catheter is guided to the area to be studied.
