"I am not young enough to know everything."Oscar Wilde.
There is insufficient knowledge among providers and patients/caregivers of ionizing radiation exposure from medical imaging examinations. This study used a brief, interactive educational intervention targeting the topics of best imaging practices and radiation safety early in health professions students' training. The authors hypothesized that public health, medical, and physician assistant students who receive early education for imaging appropriateness and radiation safety will undergo a change in attitude and have increased awareness and knowledge of these topics.
The authors conducted a 1.5-hour interactive educational intervention focusing on medical imaging utilization and radiation safety. Students were presented with a pre/postquestionnaire and data were analyzed using tests and multivariate analysis of variance.
A total of 301 students were enrolled in the study. There was 58% ( < .01) and 85% ( < .01) improvement in attitude and knowledge regarding appropriateness of imaging, respectively. The authors also found an 8% increase ( < .01) in students who thought informed consent should be obtained prior to pediatric computed tomographic imaging. Physical assistant students were more likely than medical students to prefer obtaining informed consent at baseline ( = .03).
A brief educational session provided to health professions students early in their education showed an increased awareness and knowledge of the utility, limitations, and risks associated with medical imaging. Incorporation of a best imagining practice educational session early during medical education may promote more thoughtful imaging decisions for future medical providers.

医疗影像检查中电离辐射暴露的相关知识，在医疗服务提供者以及患者/护理人员中了解不足。本研究在健康专业学生培训早期，针对最佳影像实践和辐射安全主题开展了简短的互动式教育干预。作者假设，接受过影像适宜性和辐射安全早期教育的公共卫生、医学及医师助理专业学生，其态度会发生改变，对这些主题的认识和了解会有所增加。
作者开展了一次时长1.5小时的聚焦于医学影像利用和辐射安全的互动式教育干预。向学生发放了课前/课后问卷，并使用检验和多变量方差分析对数据进行分析。
共有301名学生参与了该研究。关于影像适宜性的态度和知识分别有58%（P<0.01）和85%（P<0.01）的改善。作者还发现，认为在儿科计算机断层扫描成像前应获得知情同意的学生增加了8%（P<0.01）。在基线时，医师助理专业学生比医学专业学生更倾向于获得知情同意（P=0.03）。
在健康专业学生教育早期提供的简短教育课程，显示出他们对医学影像的效用、局限性及风险的认识和了解有所增加。在医学教育早期纳入最佳影像实践教育课程，可能会促使未来的医疗服务提供者做出更周全的影像决策。
