Abstract

RATIONALE AND OBJECTIVES

This study evaluates the opinions and knowledge of fourth-year US medical students regarding radiology and analyzes the influence of a required or nonrequired radiology rotation as a reflection of the effectiveness of radiology medical student education.

METHODS AND MATERIALS

Our institutional review board granted exempt status. An invitation e-mail was sent to 137 US medical schools. Upon receiving approval a second email was sent containing our voluntary anonymous online survey hyperlink to forward to their fourth-year class. Survey topics included demographics, radiology educational experiences, attitudes toward the field, and basic radiology knowledge. Responses were collected between August 4 and September 26, 2011.

RESULTS

A total of 444 fourth-year medical students from 37 medical schools participated: 89% planned to enter a nonradiology specialty, 10.8% were required to take a dedicated radiology rotation, 34.9% completed one, 77% planned to complete one by graduation, 88.4% thought radiology often changes patient care or is at least as important as physical exam, 91.4% underestimated the cancer risk of an abdomen and pelvis computed tomography by at least one order of magnitude, and 72.9% by at least two orders. Seventy-seven percent had never heard of the American College of Radiology (ACR) Appropriateness Criteria. Respondents underestimated the potential risks of magnetic resonance imaging (MRI); with 58.3% aware intravenous gadolinium can cause nephrogenic systemic fibrosis and 79.4% aware of potential injury from metallic projectiles. 40.4% indicated that non-radiologist clinicians in specific medical specialties interpret their respective imaging studies at least as accurately as corresponding subspecialty radiologists. Other results include student opinions regarding teleradiology, radiologist lifestyle, and compensation.

CONCLUSIONS

Fourth-year medical students recognize the importance of radiology but are poorly informed regarding radiation safety, MRI safety, and ACR Appropriateness Criteria, despite 34.9% having a dedicated rotation. This highlights the need for adoption of the Alliance of Medical Student Educators in Radiology curriculum.

摘要

背景与目的

本研究评估了美国四年级医学生对放射科的看法和知识，并分析了必修或非必修放射科轮转对反映放射科医学生教育效果的影响。

方法和材料

我们的机构审查委员会授予豁免地位。向 137 所美国医学院校发送了一封邀请电子邮件。在收到批准后，我们向他们的四年级班级发送了第二封电子邮件，其中包含我们自愿匿名在线调查的超链接。调查主题包括人口统计学、放射科教育经验、对该领域的态度以及基本放射科知识。答复于 2011 年 8 月 4 日至 9 月 26 日之间收集。

结果

共有 37 所医学院的 444 名四年级医学生参加了研究：89%的人计划进入非放射科专业，10.8%的人需要接受专门的放射科轮转，34.9%的人完成了轮转，77%的人计划在毕业前完成轮转，88.4%的人认为放射科经常改变患者的治疗方式，或者至少与体检同样重要，91.4%的人至少低估了腹部和骨盆 CT 检查的癌症风险一个数量级，72.9%的人至少低估了两个数量级。77%的人从未听说过美国放射学院（ACR）适宜性标准。受访者低估了磁共振成像（MRI）的潜在风险；58.3%的人知道静脉内钆可引起肾源性系统性纤维化，79.4%的人知道金属弹丸可能造成的潜在损伤。40.4%的人表示，在特定医学专业中，非放射科临床医生对各自的影像学研究的解读至少与相应的亚专科放射科医生一样准确。其他结果包括学生对远程放射学、放射科医生的生活方式和薪酬的看法。
