Trends and different educational pathways for training physicians in nuclear medicine.

The introduction of positron emission tomography/computed tomography (CT), single photon-emission CT/CT, and software packages for multimodality imaging has accelerated the need for nuclear medicine physicians to obtain more training in cross-sectional imaging, especially in CT. In recent years, the Nuclear Regulatory Commission, the Accreditation Council for Graduate Medical Education, the American Board of Radiology, and the American Board of Nuclear Medicine have promulgated new rules and regulations. In addition, the Society of Nuclear Medicine, the American College of Radiology, and the American College of Cardiology Foundation have crafted new guidelines and training requirements. All these changes have consequences for the education of physicians in nuclear medicine. Self-referral and concerns about radiation exposure from nuclear medicine examinations and CT are also affecting the education of physicians practicing nuclear medicine. The authors examine the impact of these developments on training and certification in nuclear medicine and suggest another pathway to train some nuclear medicine physicians.
