原发性肝癌的螺旋CT双期增强特征及其诊断价值

Diagnosis value of dual phase spiral CT in primary hepatocellular carcinoma and scanning characteristic

目的探讨原发性肝癌的螺旋CT双期增强特征及其诊断价值。方法回顾性分析56例经临床及手术病理证实的原发性肝癌以及增强表现。结果56例共发现82个病灶。平扫呈低密度或稍低密度,病灶密度呈“速升速降”的变化特点。结论螺旋CT双期扫描可充分反映原发性肝癌的特征,对肝癌的检出和定性准确率的提高有重要价值。

Objective:To evaluate characteristics and diagnosis value with dual phase spiral CT in pri-mary hepatocellular Carcinoma.Methods:56cases with hepatocellular Carcinoma were approved by pathology or operation and dual-phase spiral CT scanning characteristics.Were reviewed and analysed.Results:56ex-amples were found with82focuses altogether.They were low density or slightly low density in plain scan-ning;91%of cases with primary liver cancer were enhanced in arterial phase.9%were not enhanced obvi-ously;76%were revealed to be low bensity or slightly low density in portal venous phase,The density focus-es presented change characteristics of'rising and lowering rapidly'.Conclusions:Dual phase spiral CT is an important in the detection and charaterization of primary hepatocellular Carcinoma,and is very important for improving aceurate rate in detection and Characterization of primary hepatocellular Carcinoma.
