This video describes how the circulatory system works, how disease can affect blood vessels (atherosclerosis), and how doctors use angiography to test for coronary artery blockage.
Angiography or arteriography is a medical imaging technique to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins and the heart chambers. This is traditionally done by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy. The film or image of the blood vessels is called an angiograph, or more commonly, an angiogram.
Its name comes from the Greek words angeion, "vessel", and graphein, "to write or record".
