Arteriograms


An arteriogram may be performed to detect abnormalities of the blood vessels. An arteriogram is an X-ray of the blood vessels called arteries. It is performed to evaluate various vascular conditions, such as an aneurysm (a bulging, weakened area in the wall of a blood vessel), stenosis (narrowing of a blood vessel), or blockages. Other names for this procedure are angiogram and arteriography. Fluoroscopy is often used during an arteriogram. Fluoroscopy is the study of moving body structures — similar to an X-ray "movie." A continuous X-ray beam is passed through the body part being examined, and is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail. During an arteriogram, a dye is injected into an artery making the arteries visible on X-ray. The development and improvement of diagnostic procedures such as computed tomography (CT scan), ultrasound, and magnetic resonance imaging (MRI) have greatly expanded the diagnostic capabilities of the radiology department. An arteriogram may be performed in conjunction with another type of diagnostic procedure such as CT, MRI, or ultrasound, which provides greater detail to the doctor.
