Interventional radiology is a sub-specialty of radiology that utilises imaging technology to perform minimally-invasive, guided therapies for a variety of diseases in almost every organ system. In some cases such treatments are alternatives to more invasive, riskier surgical options, whereas in other cases, Interventional Radiology offers entirely novel treatments that were previously unavailable to patients. Many of the procedures are performed under local anaesthesia and require only a very short hospital stay with rapid return to normal activities.
