对２２６例手术病理证实放射性核素９９ｍＴｃ－ＰＭＴ肝细胞癌阳性显像患者作了回顾性调查，以探讨该方法诊断肝细胞性肝癌的临床价值．其中１５９例肝细胞癌，９１例于延迟显像显示肿瘤部位放射性浓聚等于或超过正常肝组织，阳性率为５７．２％，特异性为９２．５％．检出的肝肿瘤最小直径为１．２ｃｍ，肿瘤浓聚放射性药物的能力与ＡＦＰ值和肝硬化存在与否没有相关性（Ｐ＞０．０５）．结果证实９９ｍＴｃ－ＰＭＴ显像在肝细胞癌诊断中有一定价值，也有其局限性．
A retrospective investigation was performed on 226 patients with positive imaging of radionuclide 99mTc-PMT hepatocellular carcinoma confirmed by surgery and pathology to explore the clinical value of this method in the diagnosis of hepatocellular carcinoma. Among them, 159 cases of hepatocellular carcinoma and 91 cases of delayed imaging showed that the radioactive concentration in the tumor site was equal to or higher than that of the normal liver tissue. The positive rate was 57.2% and the specificity was 92.5%. The minimum diameter of liver tumors detected was 1.2 cm. There was no correlation between the ability of tumors to concentrate radiopharmaceuticals and the presence of AFP and cirrhosis (P> 0.05). The results confirmed 99mTc-PMT imaging in the diagnosis of hepatocellular carcinoma has some value, but also has its limitations.
