The Society of Interventional Radiology is a national organization of physicians, scientists, and health professionals dedicated to improving public health through disease management and minimally invasive, image-guided therapies. Intervention radiology includes using X-rays, MRI, and other imaging to move a thin tube in the body, usually in an artery, to treat a disease. An example is angioplasty for heart disease. The Web site includes a section on patient information. This section gives information on therapies for various diseases and conditions. The Web site can also help you find a doctor.
