头部和颈部区域是医学大体解剖学课程中最复杂的区域之一。使用三维（3D）模型进行解剖学教学的有效性是医学教育研究中讨论较多的话题。然而，在解剖学教育中使用头部和颈部循环的3D立体模型以前没有详细研究。本研究探讨了计算机断层血管造影（CTA）数据创建的三维立体模型是否是头颈部血管解剖学的有效教学工具。测试对象是密西西比大学医学中心的一年级医学生。评估工具包括：解剖学知识测试（学习前会话知识测试和学习后会话知识测试）、心理旋转测试（空间能力;会话前MRT和会话后MRT）和满意度调查。使用Wilcoxon秩和检验和线性回归分析对结果进行分析。共有39名一年级医学生参加了这项研究。结果表明，在3D学习课程中接触立体3D血管模型的所有学生都提高了他们正确识别头颈部血管解剖结构的能力。最重要的是，对于空间能力低的学生，3D学习课程提高了会后知识分数的水平，表现出与高空间能力的学生，表明使用3D立体模型可能是特别有价值的，这些学生与低空间能力。Anat Sci Educ 10：34-45.

The head and neck region is one of the most complex areas featured in the medical gross anatomy curriculum. The effectiveness of using three-dimensional (3D) models to teach anatomy is a topic of much discussion in medical education research. However, the use of 3D stereoscopic models of the head and neck circulation in anatomy education has not been previously studied in detail. This study investigated whether 3D stereoscopic models created from computed tomographic angiography (CTA) data were efficacious teaching tools for the head and neck vascular anatomy. The test subjects were first year medical students at the University of Mississippi Medical Center. The assessment tools included: anatomy knowledge tests (prelearning session knowledge test and postlearning session knowledge test), mental rotation tests (spatial ability; presession MRT and postsession MRT), and a satisfaction survey. Results were analyzed using a Wilcoxon rank sum test and linear regression analysis. A total of 39 first year medical students participated in the study. The results indicated that all students who were exposed to the stereoscopic 3D vascular models in 3D learning sessions increased their ability to correctly identify the head and neck vascular anatomy. Most importantly, for students with low spatial ability, 3D learning sessions improved postsession knowledge scores to a level comparable to that demonstrated by students with high-spatial ability indicating that the use of 3D stereoscopic models may be particularly valuable to these students with low spatial ability.
