[摘要] 目的 探讨实习医院现场教学与虚拟仿真教学在MRI检查技术实践教学的应用与效果。 方法 选择本校即将学习MRI检查技术的2017级医学影像学本科班142名学生，分成两组，理论教学同时进行，实践教学分为实习医院现场教学组与虚拟仿真教学组，学习结束后进行理论与实践考核，并发放问卷对教学满意度进行调查，比较两组间的差异。 结果 现场教学组的理论成绩为（88.42±9.76）分，实践成绩为（80.01±6.27）分，虚拟仿真组的理论成绩为（87.80±4.91）分，实践成绩为（79.08±6.30）分，两组比较，差异无统计学意义（P>0.05）。现场教学组的调查满意度为（90.06±3.68）分，虚拟仿真组的调查满意度为（82.83±7.22）分，两组比较，差异有统计学意义（P<0.05）。 结论 虚拟仿真教学在MRI检查技术实践教学中的应用价值与现场教学相当，可以带来相近的教学效果，学生对于现场实践教学满意度更高，有条件的教学单位可以多采用现场实践教学。

[Abstract] Objective To investigate the application and effect of live teaching and virtual simulation teaching in practice teaching of Magnetic Resonance Imaging （MRI） examination technology in a training hospital. Methods A total of 142 students from the medical imaging undergraduate class of grade 2017 who were going to study MRI examination technology in our school were selected. They were divided into the live teaching group and the virtual simulation teaching group in the training hospital according to the practice teaching， and the theoretical teaching was carried out simultaneously. After the study， the theoretical and practice assessment was carried out， and the questionnaire was distributed to investigate the teaching satisfaction， then the differences between the two groups were compared. Results The theoretical and practical scores of the live teaching group were （88.42±9.76）points and （80.01±6.27）points， while those of the virtual simulation teaching group were （87.80±4.91） points and （79.08±6.30） points，without statistically significant differences between the two groups（P>0.05）.The satisfaction of the live teaching group was （90.06±3.68） points，while that of the virtual simulation teaching group was （82.83±7.22） points，with statistically significant difference between the two groups（P<0.05）. Conclusion The application value of virtual simulation teaching in practice teaching of MRI examination technology is equal to that of live teaching， which can bring similar teaching effect. Students are more satisfied with live practice teaching， and qualified teaching units should adopt more live practice teaching.

醫学影像检查技术学是医学影像学专业和医学影像技术专业的核心课程，课程中学到的知识和技能，直接与临床医学影像检查技术岗位对接，决定了将来从事医学影像技术应具有的知识与能力。其理论教学所涉及的内容要点多，序列、参数设置复杂，很多知识点都需要记忆，学生大多是被动式听课，主动学习兴趣不高。而实践教学可以让学生理论联系实际，激发学习热情，培养学生动手能力和创新思维[1]。……
