Medical doctors who have been trained to assess and treat the injuries and diseases of patients using a variety of imaging techniques, including X-rays, positron emission tomography (PET), and magnetic resonance imaging (MRI), are known as radiologists. Some radiologists have also been educated in areas of nuclear medicine and hold certifications in nuclear radiology. The American Board of Radiology certifies the majority of medical doctors in the field, while osteopathic doctors tend to receive their certifications from the American Osteopathic Board of Radiology. Radiology certifications indicate that a doctor has received the highest level of specialized training and is capable of administering excellent care to patients.
Prior to obtaining certification, individuals must graduate from an accredited medical school and complete a four- to six-year residency and fellowship program with an emphasis on radiation safety and protection, radiation effects on the human body, and other areas critical to effective radiology practices.
