Diagnostic imaging is the use of medical imaging procedures to diagnose health conditions. Used in combination with other medical exams and tests, diagnostic imaging plays a key role in the prevention, identification and assessment of many health conditions.
Interventional imaging is the use of medical imaging in order to treat a disease or condition. Interventional radiologists use imaging techniques along with other medical devices to, for instance, deliver medication to the exact location of a disease within the body or to remove samples of diseased tissue from the body. Interventional imaging can help prevent the need for more invasive procedures, such as open surgery.
Many radiologists specialize in the imaging of specific body parts. For instance, a radiologist specializing in musculoskeletal radiology works primarily with conditions affecting bones, muscles and joints. By specializing in a specific part of the body, a radiologist is able to develop in-depth knowledge of the most effective imaging procedures and treatments for that part of the body.
