作者对84例临床诊断有肝脏病变的患者分别进行腹部CT 和放射性核素肝显像检查。两项试验的结果与临床最后诊断(外科手术、活组织检查、尸检及随访等)比较,RI 发现和排除肝脏病变的总准确率为49%;CT 为98%。其中有54例两项试验结果一致并与临床最后诊断一致;14例两项试验结果不一致;16例两项试验结果中有一项可疑。在两项结果不一致的71例中,13例RI 为假阴性,其中10例是直径小于2cm 的肝内单发或多发病灶,这些病人生化肝功能指标
The authors performed abdominal CT and radionuclide liver imaging on 84 patients with clinically diagnosed liver lesions. The results of the two trials were compared with the final clinical diagnosis (surgery, biopsy, autopsy, and follow-up, etc.). The overall accuracy of RI in the detection and elimination of hepatic lesions was 49%; CT was 98%. Among them, 54 cases had identical results and were consistent with the final clinical diagnosis; 14 cases had inconsistent results; 16 cases were suspicious. Of the 71 cases with inconsistent results, 13 were false-negative RIs, 10 of which were intrahepatic solitary or multiple lesions less than 2 cm in diameter. These patients had biochemical indicators of liver function.
