Abstract

Among 650 consecutive radioisotope liver scans there were selected 180 representing all cases in which a pathoanatomical evaluation of the liver was available. The scanning data, the clinical information, and the pathoanatomical diagnosis were reviewed independently, and the results achieved in each group were classified as evidence of normal liver, focal hepatic disease, or diffuse hepatic disease. Using pathology for verification scanning had a sensitivity of 97% and a specificity of 90% regarding detection of unspecified liver disease, which was significantly better than clinical setting alone. In diffuse hepatic disease scanning had a sensitivity of 100% and a specificity of 81%, whereas in the focal hepatic disease the corresponding figures were 78 and 97%, respectively. Passive hepatic congestion was recognized as a diffuse hepatic disease by scanning, thus representing a source of error in screening for liver disease sensu stricto. It is concluded that scanning, apart from being a rapid and simple procedure without significant inconvenenience to the patient, is a very accurate diagnostic tool that deserves more recognition in clinical departments.

摘要

在连续650例放射性核素肝脏扫描中，选取了180例代表所有可进行肝脏病理解剖评估的病例。对扫描数据、临床信息和病理解剖诊断进行了独立审查，并将每组的结果分类为正常肝脏、局灶性肝病或弥漫性肝病的证据。以病理作为验证，扫描对于未明确的肝病检测的敏感性为97%，特异性为90%，明显优于单纯临床诊断。在弥漫性肝病中，扫描的敏感性为100%，特异性为81%，而在局灶性肝病中，相应数字分别为78%和97%。扫描将被动性肝淤血识别为弥漫性肝病，因此在严格意义上的肝病筛查中是一个误差来源。结论是，扫描除了是一种快速、简单的程序且对患者没有明显不便外，还是一种非常准确的诊断工具，值得临床科室更多认可。
