原发性肝癌的螺旋CT双期增强特征及其诊断价值

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,对肝癌的检出和定性准确率的提高有重要价值

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

Purpose:Evaluation the characteristic and diagnosis value with dual phase spiral CT in prinmary hepatocellular carcinoma.Materials and Methods: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 slghtly in portal venous phase,focus presents the change characteristic of rising and lower rapidly by density.Conclusion: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.
