Angiography at the Hospitals of Methodist Health System, North Texas

What is angiogram?

Angiography is an X-ray test that produces images of the blood flow within major arteries or veins. Each test is named for the blood vessel being studied. For example, an angiogram of the aorta is called an aortagram, and an angiogram of an artery is called an arteriogram.

During angiography, a thin, flexible tube called a catheter is threaded into a blood vessel in the arm and guided to the section of blood vessel the doctor wants to study. A dye, or contrast material, is injected into the vessel to make it more visible on the X-ray pictures. The X-ray camera is placed above the patient, and moves up and down during the test.

Angiogram pictures can be produced on traditional X-ray films or stored as digital images in a computer. A regular angiogram can be used to evaluate the arteries or veins in the arms, legs, chest, or abdomen. Special angiography tests can look at the arteries near the heart, lungs, and brain.

Who needs an angiogram?

An angiogram may be recommended when a person has a possible problem with a blood vessel, such as:

Angiograms may also be used for people with detected changes in the blood vessels that lead to injured or damaged organs. This test can also be used to image a tumor’s blood supply, which can reveal the size of the tumor and help guide treatment.
