To assess the non-radiologist physicians' knowledge on the use of ionizing radiation in imaging.
Cross-sectional study utilizing an anonymous questionnaire responded by physicians in clinical and surgical specialties, divided into two parts as follows: one including questions about the physicians' characteristics, frequency of imaging studies requests and participation in professional updating events, and another part including multiple choice questions approaching general knowledge about radiation, optimization principles and radioprotection.
From a total of 309 questionnaires, 120 (38.8%) were responded, 50% by physicians in surgical specialties and 50% in clinical specialties; respectively 45% and 2.5% of physicians responded that magnetic resonance imaging and ultrasonography use ionizing radiation. Overall, the average grade was higher for surgical specialists with no significant difference, except for the question about exposure in pregnant women (p = 0.047). Physicians who are professionally updated, particularly those attending clinical meetings (p = 0.050) and participating in teaching activities (p = 0.047), showed statistically superior knowledge about ionizing radiation as compared with others.
The non-radiologist physicians' knowledge is heterogeneous and in some points needs to be improved. Multidisciplinary clinical meetings and teaching activities are important ways to disseminate information on the subject.
评估非放射科医生对成像中电离辐射使用的了解情况。
采用横断面研究，通过一份匿名问卷对临床和外科专业的医生进行调查，问卷分为两部分：一部分包括关于医生特征、成像检查申请频率以及参与专业知识更新活动的问题；另一部分包括关于辐射常识、优化原则和放射防护的多项选择题。
在总共309份问卷中，有120份（38.8%）得到回复，其中外科专业医生回复率为50%，临床专业医生回复率为50%；分别有45%和2.5%的医生回答磁共振成像和超声检查使用电离辐射。总体而言，外科专家的平均得分较高，除了关于孕妇辐射暴露的问题外，差异无统计学意义（p = 0.047）。与其他医生相比，接受过专业知识更新的医生，尤其是参加临床会议的医生（p = 0.050）和参与教学活动的医生（p = 0.047），在电离辐射知识方面具有统计学上的优势。
非放射科医生的知识水平参差不齐，在某些方面需要改进。多学科临床会议和教学活动是传播该主题信息的重要途径。
