The Aberdeen section scanner provides, in addition to conventional views, a display of the distribution of radioactivity in a tomographic section of the brain. This paper examined the value of this additional information. Scans of lesions confirmed pathologically or radiologically, along with normal and doubtful cases, were examined after a careful randomization procedure. During the course of the study each set of conventional views was examined twice, once without and once with a tomographic section view. In two out of 29 cases (7%) the lesion was diagnosed only with the aid of the tomographic section scan. Improved accuracy of diagnosis with the tomographic section view was significant at the 1% level or better.
阿伯丁断层扫描仪除了能提供传统图像外，还能显示大脑断层切片中的放射性分布情况。本文探讨了这些额外信息的价值。在经过仔细的随机化程序后，对经病理或放射学确诊的病变扫描以及正常和疑似病例进行了检查。在研究过程中，每组传统图像被检查了两次，一次不看断层切片图像，一次查看断层切片图像。在29例病例中有2例（7%）仅借助断层切片扫描才得以诊断出病变。断层切片图像在诊断准确性上的提高在1%的水平或更高水平上具有显著性。
