What is Radiology?
Radiology, also known as diagnostic imaging, is a series of tests that take pictures or images of parts of the body. This field covers two fields (diagnostic radiology and interventional radiology), both of which use radiant energy to diagnose and treat diseases. While there are several different imaging exams, some of the most common are X-ray, MRI, ultrasound, CT scan, and PET scan.
A radiologist will look at the result of a particular imaging test to find a relevant image that evaluates and supports a diagnosis. These individuals are often highly specialized medical practitioners (MDs) who focus on the interpretation of medical imaging. Radiological technologists also assist in this process as they operate and manage machines during the production of an image. After a patient undergoes imaging tests, radiologists will provide reports of their comments to the referring clinical physicians.
Diagnostic radiology uses these imaging results to identify a wide variety of problems, from broken bones to heart conditions to blood clots. Interventional radiology also uses imaging such as CT scans, MRI and ultrasound to guide medical procedures. Whether treating cancer, back pain, or liver and kidney problems, patients are often awake during these procedures. In some cases, interventional radiology eliminates the need for surgery and scope.
