A radiologist is a physician who uses imaging methodologies to diagnose and manage patients and provide therapeutic options. Physicians practising in the field of Radiology specialize in Diagnostic Radiology, Interventional Radiology, or Radiation Oncology. They may certify in a number of subspecialties. The board also certifies in Medical Physics and issues specific certificates within each discipline.
An interventional radiologist combines competence in imaging, image-guided minimally invasive procedures and periprocedural patient care to diagnose and treat benign and malignant conditions of the thorax, abdomen, pelves, and extremities. Therapies include embolization, angioplasty, stent placement, thrombus management, drainage, and ablation, among others. Training includes a minimum of three years of Diagnostic Radiology and two years of Interventional Radiology, leading to primary certification in Interventional Radiology/Diagnostic Radiology.
Interventional radiology is a medical sub-speciality 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 in comparison to open surgery. Interventional Radiology (IR) originated within diagnostic radiology as an invasive diagnostic subspecialty. IR is now a therapeutic and diagnostic speciality that comprises a wide range of minimally invasive image-guided therapeutic procedures as well as invasive diagnostic imaging.
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
