Interventional Radiology Interventional radiology uses images of interior structures of the body to diagnose and/or treat problems or disease. These images act as maps to the target area, where the doctor can then perform the needed procedures. Interventional radiologists are board-certified physicians who specialize in minimally invasive techniques to explore and treat many kinds of problems and diseases. Numerous conditions can now be treated nonsurgically, reducing risk, pain, and recovery time. Some of the uses for minimally invasive interventional radiology can include: Angiography Angioplasty and stent placement Deep vein thrombosis Kidney cancer Liver cancer Lung cancer Deep vein thrombosis Gastrostomy (feeding tubes) Hypertension and end-stage renal disease Liver disease Needle biopsy Pelvic pain (chronic) Peripheral arterial disease Pulmonary embolism Trauma Uterine fibroids Varicoceles
