Relating to or used in aortography, the imaging or visual examination of the aorta.
Derived from 'aorta' (the main artery from the heart) plus Greek 'graphia' (writing or recording). The adjective form was developed in the mid-20th century alongside modern medical imaging techniques.
When doctors wanted to see inside the aorta without opening patients up, they invented aortography—essentially X-raying this giant vessel with special dye—and suddenly they could spot dangerous weaknesses before they became emergencies.
