Interventional Radiology

What are Interventional Radiologists?

Interventional Radiologists are board-certified physicians who deliver minimally invasive treatments with less risk, less pain and less recovery time than traditional surgery. Most interventional radiology (IR) procedures are delivered via catheters through a tiny nick in the skin and imaging guidance to deliver precise treatment. Patients undergoing IR procedures are generally performed under local anesthetic or conscious sedation to help make the patient more comfortable during their procedure. Lastly, many procedures are performed at our outpatient facility and discharged same day or in the hospital with a short overnight stay.
