Interventional Radiology

Interventional radiology (IR) involves the use of fluoroscopy and specialized equipment to gain access to different structures in the body, and deliver materials for diagnostic and therapeutic purposes.

IR techniques are minimally invasive, and can lead to fewer negative outcomes, shorter anesthesia times, and brief stays. Interventional radiology can be applied to patients of all sizes. The Jack Miller-Ebrahimi Interventional Radiology Program is leading the way in training the next generation of specialists this new and growing field.
