Improving integration between basic science and clinical application is essential in medical education. Anatomy courses can do this by focusing on medical imaging interpretation. Most imaging textbooks rely on structural identification, which novice learners often struggle to apply to the health care environment, particularly in complex regions like the pelvis, which is multifaceted and differs substantially between sexes. To address this deficit, this resource extends our imaging-based tutorial series.
This tutorial was a self-administered PowerPoint incorporating X-ray, computed tomography, and magnetic resonance imaging, which are all often used for the pelvic region, as well as self-quizzing and clinical applications. Using repeated-measures, control/experimental design, the tutorial was evaluated as a review tool for 57 Australian medical students in preclerkship years. Participants were evaluated by a rating self-efficacy scale, knowledge-based testing (multiple-choice, short-answer, and identification questions), and feedback to open-ended questions.
Results indicate that the tutorial significantly improved direct knowledge ( = .006), as the experimental group's posttutorial scores for direct questions were superior by 21% on average. Significant improvements occurred specifically for direct short-answer and indirect image-identification questions.
These results suggest the tutorial is an effective review tool. While previous tutorials were evaluated as adjunct tools, this tutorial was evaluated post-anatomy teaching with similar results. Students improved in direct and applied anatomy following tutorial exposure. This suggests that the tutorial series comprises valuable review and supplementary materials. None of our tutorials have been evaluated as a sole mechanism for teaching anatomy or imaging.
在医学教育中，加强基础科学与临床应用之间的整合至关重要。解剖学课程可以通过专注于医学影像解读来实现这一点。大多数影像教材依赖于结构识别，新手学习者往往难以将其应用于医疗环境，尤其是在骨盆等复杂区域，骨盆具有多面性且男女之间存在显著差异。为了弥补这一不足，本资源扩展了我们基于影像的教程系列。
本教程是一个自我管理的PowerPoint，包含常用于骨盆区域的X射线、计算机断层扫描和磁共振成像，以及自我测试和临床应用。采用重复测量、对照/实验设计，将该教程作为57名澳大利亚医学预科学生的复习工具进行评估。通过自我效能感量表评分、基于知识的测试（多项选择题、简答题和识别题）以及对开放性问题的反馈对参与者进行评估。
结果表明，该教程显著提高了直接知识（P = 0.006），因为实验组在教程后的直接问题得分平均高出21%。直接简答题和间接图像识别题有显著提高。
这些结果表明该教程是一种有效的复习工具。虽然之前的教程被评估为辅助工具，但本教程在解剖学教学后进行评估，结果相似。学生在接触教程后，直接解剖学和应用解剖学方面都有进步。这表明该教程系列包含有价值的复习和补充材料。我们的教程都没有被评估为解剖学或影像学教学的唯一机制。
