本文对９２例临床可疑肝占位性病变患者进行了肝胶体及血池断层与平面显像，计算了肝血流灌注指数，并对照同期的病理及肝动脉造影资料，探讨了核素显像、ＣＴ及Ｂ超的诊断价值。研究表明，三种方法对肝癌及肝囊肿的诊断准确性无显著性差异（Ｐ＞０．０５），但断层显像对肝血管瘤的诊断（９３％）明显优于ＣＴ（８４％）和Ｂ超（８０％）；平面肝显像难以发现直径３ｃｍ以下的病变，对肝占位灶的检出率明显低于断层显像（Ｐ＜０．０５）。联合肝、胆道系统显像有助于降低假阳性率，其价值有待进一步探讨。
In this paper, 92 cases of clinically suspected liver space-occupying lesions in patients with liver colloid and blood pool tomography and planar imaging, the calculation of hepatic perfusion index, and control the same period of pathology and hepatic arteriography data to explore the radionuclide imaging , CT and B ultrasound diagnostic value. The results showed that there was no significant difference between the three methods in the accuracy of diagnosis of hepatocellular carcinoma and hepatic cyst (P> 0.05), but the diagnosis of hepatic hemangiomas by CT was significantly better than that of CT (84%) and B ultrasound (80%); plain liver imaging is difficult to detect lesions of diameter less than 3cm, the detection rate of liver space occupying lesions was significantly lower than that of tomographic imaging (P <0.05). Joint liver, biliary system imaging help to reduce the false positive rate, its value needs to be further explored.
