目的 探讨影像存档与传输系统(picture achieving and communicating system,PACS)在医学影像学见习教学中应用的可行性及优势。方法 选择北京大学医学部2012级和2013级八年制临床医学专业共90名学生为研究对象。将2013级47名学生设为实验组,2012级43名学生设为对照组。在医学影像学见习课中,实验组学生采用PACS系统进行教学,对照组学生采用传统胶片进行教学。教学结束后,对两组学生进行考核以检验教学效果,并对实验组学生进行问卷调查以评估其对PACS系统应用的接受情况。结果 实验组学生与对照组学生相比,阅片成绩明显提高,差异具有统计学意义(t=3.108, P<0.05)。问卷结果显示,实验组学生普遍对PACS系统应用于医学影像学见习教学予以肯定。结论 PACS系统应用于医学影像学见习教学中有利于学生对阅片技能的掌握,是值得推广的教学方法。
Objective To investigate the application values of the picture achieving and communicating system (PACS) in the practice learning in the course of medical imaging.Methods Taking 90 eight-year program medical students of class 2012 and 2013 of Peking University Health Science Center as the research object. They were divided into experimental group (n=47) and the control group (n=43) according to class of 2013 and 2012, respectively. In the experimental group, PACS was introduced in the practice learning of the medical imaging. In the control group, conventional films were used. The application values of PACS were evaluated by the results of questionnaires and examinations.Results The scores of practice learning of medical imaging in the experimental group were significantly higher than those in the control group (t=3.108, P<0.05). Based on questionnaires after the courses, all students in the experimental group were satisfied with the using of PACS in practice learning of medical imaging.Conclusions PACS is a useful tool in the practice learning of medical imaging, and could be generalized in the future.
