Radiologists use a variety of imaging techniques such as X-ray, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI) to diagnose and/or treat diseases.
In addition to the more commonly perceived bone x-ray that makes images of any bone in the body, there are also general diagnostic exams used for evaluating diseases of the small and large intestines called gastrointestinal series (GI) and barium enema (BE) procedures,these abdominal procedures are guided by fluoroscopy and performed by radiologists.
Diagnostic radiologists, through extensive clinical work and related research, may also specialize in these radiology sub-specialties:
- Breast imaging (mammograms)
- Cardiovascular radiology (heart and circulatory system)
- Chest radiology (heart and lungs)
- Emergency radiology
- Gastrointestinal radiology (stomach, intestines and abdomen)
- Genitourinary radiology (reproductive and urinary systems)
- Head and neck radiology
- Musculoskeletal radiology (muscles and skeleton)
- Neuroradiology (brain and nervous system; head, neck and spine)
- Pediatric radiology (imaging of children)
