BACKGROUND
Observational skills, including radiologic perceptual abilities, are critical for medical professionals. Numerous studies have shown the positive impact of various visual art courses on observational skills. Some institutions have even incorporated art courses into their curriculum for this purpose. However, the underlying reason for this improvement remains unclear.
AIM
This prospective, controlled study aims to determine the positive impact of a virtual art evaluation course on medical students' radiologic labeling skills and to uncover the underlying reason.
MATERIALS AND METHODS
This study examines whether a 12-week art evaluation course with monitored attendance enhances medical students' ability to detect brain abnormalities in MRI scans. Medical students participated in pre- and post-tests identifying abnormalities, while a control group received no intervention. The art course focused on elements such as composition and balance. MRI characteristics, such as the contrast-to-noise ratio (CNR), were measured to assess image quality. To evaluate test difficulty and student performance, the Discrimination Index (DI) was calculated.
RESULTS
No significant difference was found in pre-test scores between the study and control groups ( = 0.35). A significant increase in post-test scores was observed in the study group (9.52 ± 3.11 vs. 10.69 ± 2.72, = 0.04), compared to controls (8.69 ± 3.03 vs. 9.30 ± 2.88, = 0.19). A moderate positive correlation was found between score improvement and course attendance in the art group ( = 0.42, = 0.0407). Strong positive correlations were calculated between the DI and CNR in the art group ( = 0.511, = 0.0205; = 0.513, = 0.0212).
CONCLUSION
Virtual art courses, which are easy to organize and enjoyable educational activities, improve medical students' radiologic labeling skills and are associated with an increase in their contrast sensitivity.
背景
包括放射学感知能力在内的观察技能对医学专业人员至关重要。大量研究表明，各种视觉艺术课程对观察技能有积极影响。一些机构甚至为此将艺术课程纳入其课程体系。然而，这种提高的潜在原因仍不清楚。
目的
这项前瞻性对照研究旨在确定虚拟艺术评估课程对医学生放射学标注技能的积极影响，并揭示其潜在原因。
材料与方法
本研究考察了一门为期12周、有出勤监督的艺术评估课程是否能提高医学生在磁共振成像扫描中检测脑部异常的能力。医学生参加了识别异常的前后测试，而对照组未接受任何干预。艺术课程侧重于构图和平衡等元素。测量了磁共振成像特征，如对比噪声比（CNR），以评估图像质量。为了评估测试难度和学生表现，计算了鉴别指数（DI）。
结果
研究组和对照组的预测试分数没有显著差异（=0.35）。与对照组（8.69±3.03对9.30±2.88，=0.19）相比，研究组的后测试分数显著提高（9.52±3.11对10.69±2.72，=0.04）。艺术组的分数提高与课程出勤之间存在中等程度的正相关（=0.42，=0.0407）。艺术组的鉴别指数与对比噪声比之间计算出强正相关（=0.511，=0.0205；=0.513，=0.0212）。
结论
虚拟艺术课程是易于组织且有趣的教育活动，可提高医学生的放射学标注技能，并与他们的对比敏感度增加相关。
