When we want to get around in life it helps to have a map. When radiologists want to navigate in blood circulation or vascular system they use a radiological map called an angiogram. Using a small tube called a catheter, doctors inject a contrast agent that colors the blood. The flowing blood is then filmed using rapid x-ray or digital photography.
