The authors determined to what extent a computer-based program could enhance or substitute for cadaver dissection in teaching cardiac anatomy to first-year medical students.
First-year medical students (n = 175) were randomized into four groups. Group 1 (control) received no instruction, group 2 participated in cardiac dissection, group 3 viewed the computer application, and group 4 performed cardiac dissection and then viewed the computer application. Each group was tested with 10 ultrafast computed tomographic static images and 8 cardiac cadaver specimens.
The computer program plus dissection was superior to either the computer program alone or dissection alone; however, the results varied according to the subtest used to assess the outcomes.
Cardiac computer instruction after dissection resulted in dramatically improved image testing performance. However, computer instruction should not replace dissection for teaching cardiac anatomy.
作者旨在确定基于计算机的程序在向一年级医学生教授心脏解剖学过程中能够在多大程度上增强或替代尸体解剖。
将一年级医学生（n = 175）随机分为四组。第1组（对照组）未接受任何指导，第2组参与心脏解剖，第3组观看计算机应用程序，第4组先进行心脏解剖然后观看计算机应用程序。每组用10张超快速计算机断层扫描静态图像和8个心脏尸体标本进行测试。
计算机程序加解剖优于单独使用计算机程序或单独进行解剖；然而，结果因用于评估结果的子测试而异。
解剖后进行心脏计算机教学可显著提高图像测试表现。然而，计算机教学不应取代心脏解剖教学。
