Interventional Radiologists are specialized physicians who have obtained training in diagnostic radiology and subspecialized training in vascular and interventional radiology procedures. They perform minimally invasive, image guided procedures for the diagnosis and treatment of many diseases.
They use fluoroscopy, CT, US and MRI imaging to guide needle and catheters through a small access site in the skin to access the particular site in the body requiring therapy. As the inventors of angioplasty and the catheter-delivered stents, which were first used in the legs to treat peripheral arterial disease, interventional radiologists pioneered minimally invasive modern medicine. Today many conditions that once required surgery can be treated less invasively by interventional radiologists. Interventional radiology treatments offer less risk, less pain and less recovery time compared to open surgery.
