Medically reviewed by Min Clinic Staff | Updated: January 2026

Radiology, interventional: The use of image guidance methods to gain access to the deepest
interior of most organs and organ systems. Interventional radiology includes the use of balloons, catheters, microcatheters, stents, therapeutic embolization (deliberately clogging up a blood
vessel), and more. The specialty of interventional radiology overlaps with other surgical arenas, including interventional cardiology, vascular surgery, endoscopy, laparoscopy, and other minimally invasive techniques, such as biopsies. Specialists performing interventional radiology procedures today include not only radiologists but also other types of physicians, such as general surgeons, vascular surgeons, cardiologists, gastroenterologists, gynecologists, and urologists.
