Radiology & Imaging Studies
Radiology is a specialty that uses medical imaging to diagnose and treat diseases seen within the body. A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI) are used to diagnose and/or treat diseases. Interventional radiology is the performance of medical procedures with the guidance of imaging technologies.
Diagnostic radiology is concerned with the use of various imaging modalities to aid in the diagnosis of disease. Diagnostic radiology can be further divided into multiple sub-specialty areas. Interventional radiology, one of these sub-specialty areas, uses the imaging modalities of diagnostic radiology to guide minimally invasive surgical procedures.
Therapeutic radiology—as it is now called, radiation oncology uses radiation to treat diseases such as cancer using a form of treatment called radiation therapy.
