Society of Interventional Radiology

Our Mission

Interventional radiology is the cutting-edge of medicine—without the cutting. Members of the Society of Interventional Radiology (SIR) are physicians who specialize in minimally invasive, targeted treatments for many conditions that once required surgery. IR treatments offer less risk, less pain and less recovery time compared to open surgery.

SIR is a national organization of physicians, scientists and allied health professionals dedicated to improving public health through pioneering advances in image-guided therapy.

Interventional radiologists
offer the most in-depth knowledge of the least invasive treatments available coupled with diagnostic and clinical experience across all specialties. They use X-ray, MRI and other imaging to advance a catheter in the body, such as in an artery, to treat at the source of the disease internally.

As the inventors of angioplasty and the catheter-delivered stent, which were first used in the legs to treat peripheral arterial disease, interventional radiologists pioneered minimally invasive modern medicine. Today, interventional oncology is a growing specialty area of interventional radiology. Interventional radiologists can deliver treatments for cancer directly to the tumor without significant side effects or damage to nearby normal tissue.
