Interventional radiology emcompasses a variety of diagnostic and therapeutic procedures using percutaneous, mimimally invasive methods guided by imaging techniques. As an adjunct to or in lieu of surgery, these minimally invasive procedures reduce surgical risks, are less expensive and are equally or more efficient in diagnosis and therapeutic treatment than open surgical procedures.
