Interventional Imaging

A subspecialty of interventional radiology (IR) uses image-guided, minimally-invasive procedures to diagnose and treat various diseases. Interventional radiologists rely on angiography, mobile C-arm and fluoroscopy imaging systems to perform thrombolysis, embolization, biopsies, vascular and other minimally invasive procedures, which can reduce recovery time, risk and costs.
