A previously published prospective trial to assess the value of tomographic transverse section images provided by the Aberdeen Section Scanner has been repeated using gamma camera images. Reports for 192 patients were analysed and compared with the final independent clinical diagnosis. The results were also compared with those of the previous investigation. When the latest results were plotted in the form of receiver operating characteristic curves, they showed some improvement for the 'with tomography' reports. Furthermore, introduction of a diagnostic classification rating showed that for cases with a high level of independent diagnostic evidence that the liver was abnormal, reporting confidence was higher with tomography. However, a simplified analysis of abnormality ratings suggested that the differences were not statistically significant for the numbers of patients examined.
一项先前已发表的前瞻性试验，旨在评估阿伯丁断层扫描仪提供的断层横断面图像的价值，现已使用伽马相机图像重复进行。分析了192例患者的报告，并与最终的独立临床诊断结果进行比较。结果还与先前的调查结果进行了比较。当以受试者工作特征曲线的形式绘制最新结果时，“有断层扫描”的报告显示出一定的改善。此外，引入诊断分类评级表明，对于肝脏异常有高水平独立诊断证据的病例，断层扫描报告的置信度更高。然而，对异常评级的简化分析表明，所检查患者数量的差异无统计学意义。
