Radiology is one medical discipline where the use medical imaging is done to diagnose and further treat diseases in the bodies of humans. There are a variety of imaging techniques like X-ray, ultrasound, radiography, computed tomography (CT), nuclear medicine, which includes positron emission tomography (PET), magnetic resonance imaging (MRI), and fluoroscopy are used in treating and diagnosing diseases. With interventional radiology, physicians perform minimally invasive procedures in medicine with the guidance of above mentioned imaging technologies.

The modern way of practicing radiology involves many different healthcare professionals working as one team. The radiologist is one medical doctor with adequate post-graduate training and can interpret medical images, and communicate these findings to other physicians either verbally or by a report and uses imaging towards performing medical procedures that are minimally invasive. Those who are radiology nurses are involved in patient care and after procedures or imaging, which includes medicine administering, monitoring sedated patients, and monitoring vital signs. The radiographer is also addressed as radiologist technologist receives special training in using positioning techniques and sophisticated technology to produce medical images which the radiologist interprets. Depending on how the individual is trained and the radiographer may have specialization in either of the image modalities role or have expanded in image reporting roles.
