The process of recording a picture of an artery is called angiography. Angiography is a medical imaging technique used to visualize the blood vessels in various parts of the body, including arteries. It is typically performed by injecting a contrast dye into the blood vessels, which makes them visible on X-ray or other imaging modalities. Angiography helps in detecting blockages, narrowing, or abnormalities in the arteries, which can aid in diagnosing and treating various medical conditions.
