Angiography or arteriography is an imaging technique in which an X-ray image is taken 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.

Interventional studies are minimally invasive procedures that are performed using image guidance. Some of these procedures are done for diagnostic purposes, while others are done for treatment purposes. The images provide road maps that allow the Interventional Radiologist it guide instruments through the body to the areas of interest.
