What is angiographie?

Angiography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and heart chambers. This is traditionally done by injecting a radio-opaque contrast agent into the blood vessel and imaging it using X-ray-based techniques such as fluoroscopy. It is commonly used to diagnose and assess conditions such as aneurysms, atherosclerosis, and other vascular abnormalities.
