Interventional Radiology is a medical sub-specialty of radiology utilizing minimally-invasive image-guided procedures to diagnose and treat diseases in nearly every organ system. The concept behind interventional radiology is to diagnose and treat patients using the least invasive techniques currently available in order to minimize risk to the patient and improve health outcomes. These procedures have less risk, less pain and less recovery time compared to open surgery.
Interventional Radiology (IR) originated within diagnostic radiology as an invasive diagnostic subspecialty. IR is now a therapeutic and diagnostic specialty that comprises a wide range of minimally invasive imageguided therapeutic procedures as well as invasive diagnostic imaging. The range of diseases and organs amenable to image-guided therapeutic and diagnostic procedures are extensive and constantly evolving, and include, but are not limited to, diseases and elements of the vascular, gastrointestinal, hepatobiliary, genitourinary, pulmonary, musculoskeletal, and, the central nervous system. As part of IR practice, IR physicians provide patient evaluation and management relevant to image-guided interventions in collaboration with other physicians or independently. IR procedures have become an integral part of medical care.
Many minimally invasive image guided procedures performed by IR have supplanted major surgical procedures by either IR physicians educating other medical fields or IR physicians taking on a clinical role.
