摘要
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.
