Diagnostic errors are common in radiology. The gestalt impression of an image refers to the rapid holistic understanding one formulates about an image and may facilitate improved diagnostic accuracy. The ability to generate a gestalt impression is typically acquired over time and is generally not explicitly taught. Our study aims to assess whether perceptual training using second look and minification technique (SLMT) can help image interpreters formulate a holistic understanding of an image and become more accurate at evaluating medical images.
Fourteen healthcare trainees voluntarily participated in a perceptual training module, comparing the differences in detection of nodules and other actionable finding (OAF) on chest radiographs before and after perceptual training intervention. The experimental group received SLMT training, and the control group did not.
Survey results were positive for all items, with the -values . There was improvement in the performance in detection of nodules and OAF in both groups. However, this change was statistically significant only for OAFs in the control group (-value ) but not the experimental group.
SLMT training was viewed by participants as an extremely helpful educational tool. Survey results indicated that participants felt the SLMT was a beneficial educational intervention. The experimental group's detection of nodules and OAF improved after SLMT, though not statistically significantly so, which may be related to the small sample size or lack of training effect. Perceptual training using SLMT may help as a useful educational technique, help radiologists identify abnormalities, and improve workflow.
诊断错误在放射学中很常见。图像的整体印象是指一个人对图像形成的快速整体理解，可能有助于提高诊断准确性。形成整体印象的能力通常是随着时间的推移而获得的，一般不会明确传授。我们的研究旨在评估使用二次观察和缩小技术（SLMT）的感知训练是否能帮助图像解读人员对图像形成整体理解，并在评估医学图像时更加准确。
14名医疗学员自愿参加了一个感知训练模块，比较了感知训练干预前后胸部X光片上结节和其他可操作发现（OAF）检测的差异。实验组接受了SLMT训练，对照组未接受。
所有项目的调查结果都是积极的，P值……两组在结节和OAF检测方面的表现都有改善。然而，这种变化仅在对照组的OAF中具有统计学意义（P值……），而在实验组中没有。
参与者认为SLMT训练是一种非常有用的教育工具。调查结果表明，参与者认为SLMT是一种有益的教育干预。实验组在SLMT后对结节和OAF的检测有所改善，尽管在统计学上不显著，这可能与样本量小或缺乏训练效果有关。使用SLMT的感知训练可能作为一种有用的教育技术，帮助放射科医生识别异常情况，并改善工作流程。
