~(18)F-FDG正电子发射断层扫描(positron emission tomography,PET)肝细胞癌(hepatocellular carcinoma,HCC)显像阳性率偏低,~(18)F-FDG PET显像浓聚程度与癌细胞分化程度有关,多种因素影响HCC细胞对~(18)F-FDG的摄取。多种示踪剂联合显像及多模式成像有可能提高HCC诊断的阳性率。PET/CT在转移性肝癌的复发、转移方面价值优于传统影像技术。本文就PET/CT在肝癌方面研究的进展作一概述。
The positive rate of ~ (18) F-FDG positron emission tomography (PET) in hepatocellular carcinoma (HCC) was low, and the positive correlation between 18F-FDG PET imaging and carcinoma Cell differentiation, a variety of factors affect the uptake of ~ (18) F-FDG in HCC cells. Multiple tracer co-imaging and multimodality imaging may increase the positive rate of HCC diagnosis. PET / CT is superior to traditional imaging in the recurrence and metastasis of metastatic liver cancer. This article gives an overview of the progress of PET / CT in liver cancer research.
