In the summer of 2009, we began full body computed tomography (CT) scanning of the pre-embalmed cadavers in the University of Michigan Medical School (UMMS) dissection lab. We theorized that implementing web-based, self-guided clinical cases based on postmortem CT (PMCT) scans would result in increased student appreciation for the clinical relevance of anatomy, increased knowledge of cross-sectional anatomy, and increased ability to identify common pathologies on CT scans. The PMCT scan of each cadaver was produced as a DICOM dataset, and then converted into a Quicktime movie file using Osirix software. Clinical cases were researched and written by the authors, and consist of at least one Quicktime movie of a PMCT scan surrounded by a novel navigation interface. To assess the value of these clinical cases we surveyed medical students at UMMS who are currently using the clinical cases in their coursework. Students felt the clinical cases increased the clinical relevance of anatomy (mean response 7.77/10), increased their confidence finding anatomical structures on CT (7.00/10), and increased their confidence recognizing common pathologies on CT (6.17/10). Students also felt these clinical cases helped them synthesize material from numerous courses into an overall picture of a given disease process (7.01/10). These results support the conclusion that our clinical cases help to show students why the anatomy they are learning is foundational to their other coursework. We would recommend the use of similar clinical cases to any medical school utilizing cadaver dissection as a primary teaching method in anatomy education.
2009 年夏天，我们开始对密歇根大学医学院解剖实验室中经过防腐处理的尸体进行全身计算机断层扫描（CT）。我们推测，实施基于死后 CT（PMCT）扫描的基于网络的、自我指导的临床病例，将增加学生对解剖学临床相关性的欣赏，增加对横断面解剖学的了解，并提高在 CT 扫描上识别常见病理的能力。每具尸体的 PMCT 扫描都生成一个 DICOM 数据集，然后使用 Osirix 软件将其转换为 Quicktime 电影文件。临床病例由作者研究和编写，至少包含一个 PMCT 扫描的 Quicktime 电影，周围环绕着新颖的导航界面。为了评估这些临床病例的价值，我们调查了密歇根大学医学院正在使用这些临床病例进行课程学习的医学生。学生们认为这些临床病例增加了解剖学的临床相关性（平均反应 7.77/10），增强了他们在 CT 上找到解剖结构的信心（7.00/10），并增强了他们识别 CT 上常见病理的信心（6.17/10）。学生们还认为，这些临床病例帮助他们将来自多门课程的材料综合成一个给定疾病过程的整体图像（7.01/10）。这些结果支持了这样的结论，即我们的临床病例有助于向学生展示他们所学的解剖学为何是他们其他课程的基础。我们建议任何将尸体解剖作为解剖学教育主要教学方法的医学院都使用类似的临床病例。
