Our Dedicated Interventional Radiology Team

What are Interventional Radiologists?

Interventional radiologists are board certified physicians who specialize in minimally invasive, targeted treatments.  They offer the most in-depth knowledge of the least invasive treatments available coupled with diagnostic and clinical experience across all specialties.  They use x-rays, MRI and other imaging to advance a catheter in the body, usually in an artery, to treat at the source of the disease non-surgically.  As the inventor of angioplasty and the catheter-delivered stent, which were first used in the legs to treat peripheral arterial disease, interventional radiologist's pioneered minimally invasive modern medicine.

Today many conditions that once required surgery can be treated non-surgically by interventional radiologists.  Interventional radiology treatments offer less risk, less pain and less recovery time compared to open surgery.

What type of Training Does an Interventional Radiologist Receive?

Interventional radiology is a recognized medical specialty by the American Board of Medical Specialties.  Interventional radiologists are board-certified physicians with additional advanced training in minimally invasive, targeted treatments performed using imaging to guide them.  Their board certification includes both Vascular and Interventional Radiology and Diagnostic Radiology which are administered by the American Board of Radiology.
