What are Radiologists


the science dealing with X-rays and other high-energy radiation, esp. the use of such radiation for the diagnosis and treatment of disease


Radiologist Physicians:

Radiologist physicians are medical doctors (MDs) who specialize in diagnosing and/or treating diseases and injuries using medical imaging technology and techniques such as X-Rays, Computer Tomography (CT), Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), and Ultrasound. Radiologists graduate from accredited medical schools, pass a licensing examination, and then go on to complete a residency of at least four years of specialized post-graduate medical education in various medical disciplines associated with radiology such as radiation safety and protection, the effects of radiation on the human body, and appropriate performance and interpretation of quality radiological and medical imaging examinations.

Radiologist physicians often complete a fellowship that involves one or two additional years of specialized training in a particular subspecialty of radiology such as breast imaging, Interventional Radiology and Neuroradiology.

Radiology Services:

Radiologists perform a variety of important physician services related to the safety and well-being of patients.

  • Radiologists act as consultants to the referring doctor by aiding in choosing the proper examination, interpreting the results obtained from medical imaging, and in utilizing test results to treat various medical conditions.
  • Radiologists treat diseases by means of radiation or perform minimally invasive procedures such as image-guided surgery (Interventional Radiology).
  • Radiologists correlate medical image findings with other examinations and tests.
  • Radiologists direct radiology technicians and other medical support staff who operate and maintain the imaging equipment in the proper performance of exams and testing.
  • Radiologists are at the forefront of imaging technology offering advice and suggestions for improvements and safety related to the development, advancement and implementation of CT, MRI, PET as well as minimally invasive procedures such as endovascular treatment of aneurysm and tumors and percutaneous biopsies.
  • Radiologists ensure quality and safety in medical imaging. Radiology procedures are medically prescribed and should only be conducted by appropriately trained and certified physicians under medically necessary circumstances. Radiologist physicians have five to seven years of specialized post-medical school training in radiation safety to ensure the optimal performance of radiological procedures and interpretation of medical images.
