摘要

学习心脏形态学在很大程度上涉及空间能力,研究表明,创新的三维可视化技术可加快和提高学习效果。比较这些教学工具及其教学效果的研究并不多见,而且很少有研究涉及复杂的先天性心脏缺陷。本研究比较了三维打印、混合现实(MR)观看三维网格和标准心脏 CT 切片图像对医学生理解复杂先天性心脏缺陷形态的影响,同时测量了客观理解水平和主观教育体验。本研究的目的是比较医学生对三维打印模型、磁共振三维可视化和轴向二维 CT 切片的形态理解和用户体验,以检查复杂先天性心脏缺损的形态细节。中位数为四年级(二年级至六年级不等)的医学生通过三种不同的模式检查了五种不同复杂先天性心脏缺损中的三种:三维打印模型、MR 观察三维网格和心脏 CT 切片,并回答有关形态和用户体验的问卷。我们收集了完成任务的时间、诊断准确性和用户体验数据,并进行了分组比较。所有模式的任务时间相似。磁共振可视化的正确率更高,也是总体上首选的模式。医学生更喜欢并能更好地理解复杂先天性心脏病的三维模型,而无需花费比三维打印或二维 CT 图像更多的时间。

Comparing assisting technologies for proficiency in cardiac morphology: 3D printing and mixed reality versus CT slice images for morphological understanding of congenital heart defects by medical students.

Learning cardiac morphology largely involves spatial abilities and studies indicate benefits from innovative 3D visualization technologies that speed up and increase the learning output. Studies comparing these teaching tools and their educational output are rare and few studies include complex congenital heart defects. This study compared the effects of 3D prints, mixed reality (MR) viewing of 3D meshes and standard cardiac CT slice images on medical students' understanding of complex congenital heart defect morphology, measuring both objective level of understanding and subjective educational experience. The objective of this study was to compare morphological understanding and user experiences of 3D printed models, MR 3D visualization and axial 2D CT slices, in medical students examining morphological details in complex congenital heart defects. Medical students in the median 4th year of study (range 2nd to 6th) examined three of five different complex congenital heart defects by three different modalities: 3D printed model, MR viewed 3D mesh, and cardiac CT slices, answering a questionnaire on morphology and user experience. Time to complete task, diagnostic accuracy, and user experience data were collected and compared on group level. Task times were similar for all modalities. The percentage of correct answers was higher with MR visualization, which was also the preferred modality overall. Medical students both prefer and better understand the morphology of complex congenital heart disease with 3D models viewed using MR, without spending more time than with 3D prints or 2D CT images.
