Diagnostic Testing


Pulmonary Angiogram

An angiogram of the lung is an X-ray test that uses fluoroscopy to take pictures of the blood flow within the blood vessels of the lung. A thin flexible tube called a catheter is usually placed into a blood vessel in the groin or just above the elbow and guided through the heart to the lungs. Then a dye (contrast material) that contains iodine is injected into the vessel being studied to make it more visible on the X-ray pictures.

Lung (pulmonary) angiogram is used to evaluate the arteries that lead to the lungs (pulmonary arteries) and the blood vessels within the lungs. It can also detect narrowing or a blockage in a blood vessel that slows or prevents blood flow. Angiogram pictures can be produced on regular X-ray films or stored as digital images in a computer.
