目的 探讨3D Slicer软件辅助基于案例的（case-based learning，CBL）教学法在癫痫专科医生术前评估教学中的应用效果。 方法 选取2022年10月—2023年6月在首都医科大学宣武医院神经内科癫痫病房进修学习的46名癫痫专科医生为研究对象，采用数字表法随机分为传统教学组和3D Slicer辅助CBL教学组，在教学结束后采用理论考核和迷你临床评价（mini clinical evaluation，Mini-CEX）量表对两组学员的学习效果进行评估，并采用问卷调查学员的学习兴趣及满意度。 结果 试验组在理论考核、Mini-CEX量表评估方面分别为（84.04±3.56）分和（23.87±1.14）分，均优于对照组的（77.57±4.25）分和（21.57±1.38）分，差异有统计学意义（P<0.05）。试验组学员的学习兴趣及满意度也高于对照组。 结论 3D Slicer辅助CBL教学法有助于学员对颅脑解剖和癫痫术前定位知识的掌握，提升教学效果，值得进一步探索和推广。

Objective To explore the application effect of the 3D Slicer software-assisted case-based learning (CBL) teaching in the preoperative assessment teaching for epilepsy specialists. Methods Forty-six epilepsy specialist doctors who underwent advanced training in the neurology department's epilepsy ward of a hospital in Beijing from October 2022 to June 2023 were selected as the research subjects. They were randomly divided into the traditional teaching group and the 3D Slicer-assisted CBL teaching group. After completing the teaching sessions, the learning outcomes of both groups were assessed through theoretical examinations and the mini clinical evaluation (Mini-CEX) assessment scale. A questionnaire was also used to survey the learners' study interests and satisfaction. Results In the experimental group (3D Slicer-assisted CBL teaching group), the scores in the theoretical examination and Mini-CEX assessment were (84.04±3.56) and (23.87±1.14), respectively, both superior to those in the traditional teaching group of (77.57±4.25) and (21.57±1.38), with statistically significant differences (P<0.05). The experimental group members also exhibited higher levels of learning interest and satisfaction, compared to the control group. Conclusion The 3D Slicer-assisted CBL teaching model contributes to the mastery of cranial anatomy and preoperative epilepsy localization knowledge, enhancing teaching effectiveness. which is worth further exploration and promotion.
