The Radiologist

Who is the radiologist?

Radiologists are medical doctors (MDs) or doctors of osteopathic medicine (DOs) who have completed a four year residency in either diagnostic radiology or radiation oncology. A radiologist may act as a consultant to another doctor who is caring for the patient, or act as the patient's primary doctor in treating a disease (such as a radiation oncologist).

Following the residency, most radiologists and radiation oncologists become board-certified by the American Board of Radiology (for a medical doctor) or the American Osteopathic Board of Radiology (for an osteopathic doctor). Some go directly into practice, while others enter fellowship programs for additional training in a specialized area, such as the following:

As a result of increasing knowledge and levels of technology in the field, radiology has become highly specialized, as have most other medical and surgical specialties. The current trend is for radiologists to become specialized in a particular discipline, such as cardiology (the study and treatment of the heart) or neurology (the study and treatment of the brain and nervous system).

Board-certified radiologists must adhere to the Practice Standards of the American College of Radiology.
