Interventional radiology (IR) is a medical specialty that uses imaging guidance—such as X-ray, CT, MRI, or ultrasound—to perform minimally invasive treatments. These procedures often replace open surgery, offering less risk, pain, and recovery time, and are typically done on an outpatient basis without general anesthesia.
What Interventional Radiologists Do
Interventional radiologists are board-certified physicians trained to guide small instruments, like catheters, through blood vessels or other pathways to treat disease through the skin (percutaneously). Their advanced training is recognized by the American Board of Medical Specialties.
A Brief History
Developed in the 1970s, IR began with the invention of angioplasty and catheter-delivered stents, revolutionizing treatment for vascular disease. Today, thousands of interventional radiologists across the U.S. provide innovative, image-guided care.
Advantages of Interventional Radiology
- Minimally invasive with no large incisions
- Reduced pain, risk, and recovery time
- Often lower cost and shorter hospital stays
Common Interventional Procedures
- Angiography & Angioplasty: Diagnose and open blocked arteries or veins.
- Stenting & Stent-Grafts: Reinforce or reopen narrowed vessels.
- Embolization: Block blood flow to aneurysms, tumors, or fibroids.
- Chemoembolization: Deliver cancer-fighting agents directly to tumors.
- Needle Biopsy: Obtain tissue samples without surgery.
- TIPS: Improve blood flow in patients with severe liver disease.
- Uterine Fibroid Embolization (UFE): Treat fibroids or control bleeding.
- Vertebroplasty: Stabilize painful spinal fractures.
- Varicose Vein or Varicocele Treatment: Relieve discomfort and improve circulation.
As technology advances, interventional radiology continues to expand, offering precise, image-guided treatments that minimize the need for traditional surgery.
