应用T-PACS提高临床医学八年制学生影像学判读能力

目的：探讨如何在临床医学八年制学生影像学教学中，建立并应用教学图像存储和传输系统（teaching-picture archiving and communication system，T-PACS）的方法和效果。方法将60名临床医学八年制学生分为对照组（传统教学）和实验组（传统教学结合T-PACS）进行影像学临床教学。针对实验组制作多媒体教学片，实施临床读片教学，结合T-PACS建立图像数据库；设立阅览室，增加课堂教学及以问题为导向的课后作业。针对两组学生实施识图能力客观考核和教学满意度问卷调查，比较教学效果。计量资料以均数±标准差表示，两组学生读片能力考核总分比较行t检验。结果实验组学生客观读片能力明显提高[对照组成绩（86.92±4.68）分，实验组成绩为（90.08±4.52）分]，差异具有统计学意义（P=0.010）；在呼吸科和骨科考题方面两组学生的满分率差异具有统计学意义（P=0.006；P=0.035）。问卷调查提示，大多数学生对应用T-PACS参与影像学教学表示肯定和支持。结论在八年制影像学教学中，应用教学专用的T-PACS能提高教学质量，值得进一步推广。

Application of teaching-picture archiving and communication system to improve the medical image reading ability of eight-year-program medical students

Objective To evaluate the application effect of teaching-picture archiving and communication system （T-PACS） in training image reading ability of eight-year-program students. Methods Sixty students were divided into two groups： control group （applying traditional teaching method） and experimental group （applying traditional teaching method and T-PACS） when doing clinical medical image reading ability training. Making multimedia teaching movie, clinical image reading teaching and establishing image database by T-PACS were used in experiment group. Mean-while, reading room was set up and classroom teaching and problem-oriented assignments were in-creased. Finally objective evaluation of image recognition ability and questionnaire were used to compare the teaching effect. Measurement data were expressed as x±s. Total scores of image reading were am-alyzed by t test. Full score rates were analyzed by X2 test. Results The results showed that the score of medical image reading ability was higher in experimental group （90.08±4.52） than in control group （86.92±4.68） （P=0.010）. There were differences in respiratory and orthopedic full score rate （P=0.006;P=0.035）. Most students thought that application of T-PACS could effectively improve the teaching and learning quality. Conclusions Application of T-PACS can improve the medical image reading ability of eight-year-program medical students and is worth further promoting.
