Background
Pediatric nuclear medicine is evolving, and its practice patterns are uncertain. Knowledge of the current trends in pediatric nuclear medicine might be helpful to direct local decisions, including expectations for patient care, needs for capital acquisitions, and staffing recruitment strategies.
Objective
To provide data regarding the current practice of pediatric nuclear medicine via a Society for Pediatric Radiology (SPR) membership survey.
Materials and methods
The SPR emailed our 25-question survey to all 1,847 SPR members in August 2018 and we accepted responses until April 2019. Questions focused on nuclear medicine staffing, positron emission tomography (PET) utilization, and radiotherapy availability. Respondents could indicate their affiliated hospital, which we used for data cataloguing only. Analysis of survey responses was blinded to reported institution. We analyzed response data using contingency tables. Independence testing between categorical variables based on proportions of physicians with additional nuclear medicine board certification was performed on a subset of questions regarding PET and therapy practices.
Results
Sixty-seven people from at least 29 hospitals responded to the survey, including all 10 of the 2018–2019 U.S. News & World Report best children’s hospitals. The majority (48/67, 71.6%) of respondents indicated that pediatric nuclear medicine examinations were interpreted in the pediatric radiology department by pediatric radiologists and that most physicians interpreting the exams (43/67, 64.2%) did not have subspecialty certification in nuclear medicine or nuclear radiology. Most facilities offered PET/CT (57/67, 85.1%); few offered PET/MRI (12/67, 17.9%). Most facilities offered radiotherapies (57/67, 85.1%) but at most of these facilities (30/57, 52.6%), fewer than half the physicians who cover nuclear medicine were approved to administer therapies. In the subset analyses based on proportion of physicians with additional nuclear medicine board certification, there were statistically significant differences between the groups in availability of PET/MRI, lutetium-177 dotatate therapy programs, and percentages of physicians approved to administer therapies.
Conclusion
Pediatric nuclear medicine is largely practiced by pediatric radiologists without subspecialty certification. Staffing, PET practices and therapies vary among practices, in part associated with the number of radiologists with nuclear medicine board certification.
