Radiology is the study of images of the human body. A Radiologist is a physcian (M.D. or D.O.) who has become a specialist in Radiology - a doctor who has taken additional training in the interpretation of medical images and the performance of imaging procedures. This training usually takes 5 - 6 additional years after completing Medical or Osteopathic School.

Although Radiology began with the use of X-Rays and large flat sheets of photographic films, the modern Radiologist now has a variety of tools for "taking pictures" of living patients. Many of these newer tools create an image with a computer (CT - computed tomography) and some do not use any X-Rays, nor radiation of any kind - such as MRI (Magnetic Resonance Imaging) and US (Ultrasound).

Radiologists must have a great understanding of Anatomy, Pathology, and Physiology in order to make accurate diagnoses. More About Radiology
