The role of radiology in preclinical anatomy: a critical review of the past, present, and future

Radiology has been an increasingly important component of preclinical anatomy instruction since the 1960s. The global status of medical imaging pedagogies and radiologists' roles in medical anatomy education is not well established but is important in determining the specialty's contribution to undergraduate medical education. PubMed was searched with various combinations of MeSH terms including "radiology," "undergraduate medical education," and "anatomy." Articles were reviewed for relevance, and referenced articles of possible relevance were hand-traced to ensure a wide capture of articles. Although more medical schools around the world are using medical imaging to teach anatomy, some regions, such as the United States, show a decline in the proportion of imaging taught by radiologists. Lectures, small group discussions, and self-instruction remain the mainstay of current pedagogies and have witnessed dramatic changes over the past few decades with respect to the types of imaging used. Newer pedagogies use contextual and hands-on experiences to improve spatial and application principles. Qualitative and quantitative studies report somewhat mixed results of pedagogical efficacies but demonstrate generally high acceptance by students and instructors and often significant exam score improvement. Radiology as a specialty must overcome several challenges for it to become more involved in anatomy education, including teaching incentives and protected academic time. As anatomy instruction and clinical medicine grow increasingly digital, it is ever more important that radiologists continue to develop new anatomy pedagogies and contribute to anatomy education in greater roles.
