what is a pulmonary angiogram used for
An angiogram, also called an arteriogram, is an X-ray image of the blood vessels. It is performed to evaluate various vascular conditions, such as an aneurysm (ballooning of a blood vessel), stenosis (narrowing of a blood vessel), or blockages. A pulmonary angiogram is an angiogram of the blood vessels of the lungs. A pulmonary angiogram may be used to assess the blood flow to the lungs. One of the primary indications for the procedure is the diagnosis of a pulmonary embolus (clot).
