目的 探讨以问题为导向教学 (PBL)与传统教学(LBL)相整合的教学模 式在医学影像学中的教学效果。方法 通 过闭卷考试和问卷调查相结合的方式， 对比分析应用LBL教学模式的5年制临床 医学班(LBL组)和应用PBL与LBL整合教学 模式的5年制临床医学班(PBL+LBL组)在 医学影像学中的教学成果。结果 在教师 队伍师资力量无显著差别的情况下，闭 卷考试结果显示PBL+LBL组的考试成绩明 显优于LBL组(P=0.006)；问卷调查结果 显示应用PBL与LBL整合的教学模式进行 教学，同学们对学习满意度以及对教师 教学满意度方面均比较认可。结论 在医 学影像学中应用PBL与LBL整合的教学模 式效果更好，能够提高该学科的教学质 量。

Objective The aim of this study was to evaluate the value for PBL and LBL teaching method in diagnostic radiology education. Methods The undergraduate medical students of 2 classes were selected as the study objects. LBL teaching method was used for one class of undergraduate students and PBL+LBL teaching method was used for another class of undergraduate students in diagnostic radiology education. The results of exam and questionnaire between two groups were contrastly analysized. Results Faculty was no significant difference between two classes. The score of exam of undergraduate students with PBL+LBL teaching method were significant better than that of undergraduate students with LBL teaching method. Result of questionnaire of undergraduate students with PBL+LBL teaching method was better than that of undergraduate students with LBL teaching method. Conclusion PBL+LBL teaching method is more suitable to medical students in diagnostic radiology education
