原发性肝癌的螺旋CT双期增强特征及其诊断价值

Diagnoses Value of Dual Phase Spiral CT in Primary Hepatocellular Carcinoma and Scanning Characteristic

目的:探讨原发性肝癌的CT双期增强特征及其诊断价值。材料与方法:回顾性分析56例经临床及手术病理证实的原发性肝癌双期增强表现。结果:56例共发现82个病灶。平扫呈低密度;肝动脉期91%强化,9%无明显强化;门脉期76%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:CT双期扫描可充分反映原发性肝癌的特征。

Purpose： Evaluation the characteristic and diagnosis value with dual phase spiral CT in prinmary hepatocellular carcinoma. Materials and Methotls： We review analysed 56 examples hepatocellular carcinoma that had approved by pathology verify or surgical operation dualphase spiral CT scanning characteristic. Results： 56 examples find 82 focuses altogether. They were reveal the low density, or the low density slightly in plain scanning; 91% of primary liver cancer were enhanced in arterial phase. 9% were not enhanced obviously; 76% were reveal the low density or the low density sightly in portal venous phase, focus presents the change characteristic of rising and lower rapidly by density. Con. dusion： Dual phase spiral CT is a important value in the detection and charaterization of primary hepatocellular carcinoma, it can improve rate of accuracy examine and determine the nature.
