【摘要】 目的 使用3D-Slicer软件实现颅内鞍区解剖结构的三维重建，探讨其在神经外科住培医生鞍区病变手术教学中的应用价值。方法 选取2021年6月至2023年6月于西安交通大学第二附属医院神经外科轮转的61名住培医生为研究对象，随机将其分为试验组（n=31）和对照组（n=30）。试验组采用神经外科住培教材、二维影像资料（MRI和CT）及经鼻治疗鞍区病变手术视频的同时，应用3D-Slicer软件实现鞍区病变及鞍旁结构的三维影像重建并进行相关临床知识讲解；对照组不应用3D-Slicer软件，其余授课内容同试验组。比较两组的理论考试成绩、问卷调查结果。结果 试验组的理论考试成绩显著高于对照组，差异具有统计学意义（P<0.05）。试验组在增强对鞍区病变诊治的认识、鞍区病变解剖结构改变的原因、教学内容兴趣性、对知识点理解程度、学习效率方面满意度高于对照组（P<0.05）。结论 将3D-Slicer技术应用于神经外科住培教学中，能较好地解决教学中的各种问题，提高了住培医生的学习兴趣、学习效率及临床思维能力，起到了改善教学效果的作用，值得进一步推广。更多还原

【Abstract】 Objective To realize the three-dimensional reconstruction of the anatomical structure of the intracranial sellar region by using 3D-Slicer software, and to explore its application value in the surgical teaching of sellar region lesions in neurosurgical resident doctors. Methods From June 2021 to June 2023, 61resident doctors who were rotated in the neurosurgery department of the Second Affiliated Hospital of Xi’an Jiaotong University were selected as the research objects and randomly divided into experimental group(n=31)and control group(n=30). The experimental group used residential training materials, two-dimensional image data(MRI and CT) and nasal surgery video of neurosurgery department for the treatment of sellar region lesions,while 3D-Slicer software was used to realize the three-dimensional image reconstruction of sellar region lesions and parasellar structures and explain the relevant clinical knowledge; the control group did not use3D-Slicer software, and the rest of the teaching content was the same as the experimental group. The theoretical test scores and questionnaire survey results of the two groups were compared. Results The theoretical test score of the experimental group was significantly higher than that of the control group, and the difference was statistically significant(P<0.05). The satisfaction of the experimental group in enhancing the understanding of the diagnosis and treatment of sellar region lesions, the causes of changes in the anatomical structure of sellar region lesions, the interest of teaching content, the degree of understanding of knowledge points, and learning efficiency were higher than those of the control group(P<0.05). Conclusion The 3D-Slicer technology applied in the resident training teaching in neurosurgery department can better solve various problems in teaching, improve the learning interest, learning efficiency and clinical thinking ability of resident doctors,and play a role in improving the teaching effect, which is worthy of further promotion.更多还原
