Angiogram Of The Lung

Content provided by Healthwise

Test Overview

An angiogram of the lung is an X-ray test that uses a special dye and camera (fluoroscopy) to take pictures of the blood flow in the blood vessels of the lung.

During an angiogram, a thin tube called a catheter is placed into the femoral blood vessel (femoral vein) in the groin or just above the elbow (brachial vein). The catheter is guided to the area to be studied. Then an iodine dye (contrast material) is injected into the vessel to make the area show clearly on the X-ray pictures. The angiogram pictures can be made into regular X-ray films or stored as digital pictures in a computer.

Lung (pulmonary) angiogram is used to check the arteries that lead to the lungs (pulmonary arteries) and the blood vessels in the lungs. It can also find narrowing or a blockage in a blood vessel that slows or stops blood flow. See an image of an angiogram showing the blood flow of the lungs .
