摘要目的 探讨3D打印教学模具在辅助医学影像诊断学本科教学中的应用价值.方法 选取上海交通大学医学院口腔医学专业学生为研究对象,其中2012级40人为对照组,2013级38人为实验组;两组教学皆为33学时,其中理论授课28学时,实习小讲课5学时.实验组采用3D打印教学模具联合PPT完成医学影像诊断学理论授课,对照组仅采用传统PPT授课.课后实验组学生填写教学质量问卷,两组学生均参加理论考试.应用SPSS 24.0对两组成绩行t检验.结果 教学质量问卷显示:3D打印教学模具联合PPT授课提高了学生的学习兴趣,满足了多数学生的学习要求,取得了满意的效果.实验组学生循环系统理论平均考试成绩[(8.320±2.352)分]高于对照组[(6.150±1.284)分];运动系统平均成绩[(6.810±1.347)分]也高于对照组[(3.840±0.985)分],差异均有统计学意义.结论 3D打印模具联合PPT授课方式可提升医学生影像解剖结构学习效果和教学质量,在医学影像诊断学本科教学中具有应用价值.

abstractsObjective To evaluate the effect of 3D printing models applied to Medical Imaging Di-agnosis Undergraduate Teaching. Methods Students in the year 2012/2013 of Shanghai Jiao Tong Univer-sity School of Medicine stomatology specialty were chosen for this study, including 38 students in the exper-imental group (2013) and 40 students in the control group (2012). All of them were taught by the same group of teachers, including 28 core curriculum hours and 5 practice class hours. 3D printing technology with PPT was applied to the experimental group in the medical imaging diagnostic teaching, and conventional teaching including PPT and usual models in the control group. Medical students were given a test about cardiovascular system and tasked with completion of drawing hand and foot bones. Students in experimental group were also asked to complete a questionnaire about their experience. Results The questionnaire showed that 3D printing teaching molds with PPT was of great significance to improve the students interest in learning imaging anatomy, to meet the vast majority of students' learning requirements, and to achieve satis-factory results. The average scores of the circulatory system test in the experimental group were higher than that of the control group [(8.32 ±2.352) vs. (6.15 ±1.284), P<0.05)]. Students in experimental group per-formed better than students in the control group on the Locomotor system test [(6.81 ±1.347] vs. (3.84 ± 0.985), P<0.01]. Conclusions 3D printing mold combined with PPT teaching method can promote the med-ical imaging anatomy structure, learning effect and teaching quality, and has practical value in the under-graduate teaching of medical imaging diagnosis.
