Definition: In Greek, "arteria" means blood vessels, but in biblical Hebrew, they refer to vessels of the heart. "Arteriography," therefore, describes medical processes that involve measuring and drawing out the blood from these vessels. This process can be performed through a surgical procedure or by direct examination of blood vessels. For example, during a CT scan, physicians use an X-ray machine to visualize blood vessel anatomy within the body; this helps in diagnosing diseases such as heart disease and stroke.
