Objective To analyze the effect of 3-D printing model-assisted traditional medical imaging technology in clinical teaching for neurosurgery postgraduates and explore new education teaching methods. Methods We taught junior neurosurgery postgraduates typical cases by using traditional medical imaging technology. The 3-D printing model-assisted traditional medical imaging technology was used in secondary teaching. We evaluated the new method by questionnaires and direct questions after teaching course. Results Students generally relfected that the sensory understanding and spatial recognition of the disease had a very big promotion after integrating the two technologies. However, the problems existing in current 3-D printing technology, such as low printing speed and shortness of simulation were the obstacles to the further understanding of diseases for students. Conclusion In the teaching field of neurosurgery postgraduates, 3-D printing model-assisted traditional medical imaging technology is a great potential method. With the development of 3-D printing technology, the advantage will become even more apparent.%目的分析快速成型技术即3D打印辅助医学影像技术在神经外科研究生教学中的作用，探索教学新方法。 方法利用医学影像技术对神经外科低年级研究生进行典型病例的教学；使用3D打印辅助医学影像技术进行二次教学。使用现场提问、调查问卷等方式评估学生对新方法的反映。 结果学生普遍认为两种技术结合后，对疾病的感觉理解、空间认识能力有了很大的提升。但当前3D打印技术存在的问题，如打印时间长、不能完全模拟病变等，是限制学生认识水平进一步提升的障碍。 结论在神经外科研究生教学领域，3D打印辅助医学影像技术是一个非常有潜力的教学方法，随着3D打印技术的提高，这种优势将更加明显。
