Angiography: A Core Technology in Modern Interventional Imaging

Angiography is a minimally invasive imaging technique in which a contrast agent is injected into the blood vessels to visualize vascular anatomy. Because X-rays cannot penetrate the contrast medium, this technique enables clear imaging of blood vessels and is widely used to detect vascular abnormalities.

With the continuous advancement of interventional radiology, angiography has become a cornerstone in clinical diagnosis and treatment. It plays a crucial role in interventional procedures, particularly in the diagnosis and management of diseases affecting the head and neck, central nervous system, cardiovascular system, tumors, and peripheral vasculature.
