Angiography

Angiography is a medical imaging technique that uses X-rays to visualize the inside of blood vessels after injecting a contrast agent. The term combines anatomy, angi- (blood vessels), and -ography (writing or recording). In practice, clinicians map arterial structures to diagnose blockages or abnormalities, typically involving specialized equipment and real-time fluoroscopy. It’s a high-stakes, technical word common in radiology and vascular contexts.
