Ultrasound is used increasingly in medical practice as a tool for focused bedside diagnosis and technical assistance during procedures. Widespread availability of small portable units has put this technology into the hands of many physicians and medical students who lack dedicated training, leaving the education and introduction of this key modality increasingly to physicians from other specialties. We developed a radiology-led program to teach ultrasound skills to preclinical medical students.
To develop this new ultrasound program we 1) established a program leader, 2) developed teaching materials, 3) created a hands-on interactive program, and 4) recruited the necessary instructors. The program was piloted with the first-year medical student class of 154 students. The introductory session was assessed by pre- and post-activity Likert scale-based surveys.
Of 154 (68.8%) students, 106 completed a voluntary online survey before starting the program and 145 students (94.2%) completed a voluntary survey after the session. Students found the program educationally valuable (4.64 of 5) and reported that it improved their understanding of ultrasound imaging (4.7 of 5). Students' reported confidence in identifying abdominal organs, intra-abdominal fluid, and Morison pouch that was significantly higher on the postactivity survey compared to the presurvey (P < .001 for all).

超声在医学实践中越来越多地被用作一种工具，用于在床边进行重点诊断以及在操作过程中提供技术协助。小型便携式超声设备的广泛普及，使得许多缺乏专业培训的医生和医学生也能使用这项技术，这使得这一关键技术的教育和推广越来越多地依赖于其他专业的医生。我们开展了一项由放射科主导的项目，旨在向临床前医学生传授超声技能。
为了开展这个新的超声项目，我们1）确定了项目负责人，2）编写了教材，3）创建了一个实践互动项目，4）招募了必要的教员。该项目在154名一年级医学生班级中进行了试点。入门课程通过基于李克特量表的课前和课后调查进行评估。
154名学生（68.8%）中，106名在项目开始前完成了一项自愿在线调查，145名学生（94.2%）在课程结束后完成了一项自愿调查。学生们认为该项目具有教育价值（满分5分，平均分为4.64），并表示该项目提高了他们对超声成像的理解（满分5分，平均分为4.7）。与课前调查相比，学生们在课后调查中报告称，他们识别腹部器官、腹腔内液体和莫里森隐窝的信心显著更高（所有项目P < 0.001）。
我们开展了一项由放射科主导的项目，向临床前医学生传授超声技能。学生们认为这次经历有趣且具有教育价值。
