62例原发性肝癌螺旋CT双期增强扫描分析

Analysis of dual phase enhancement spiral CT scanning in 62 cases of primary hepatocellular carcinoma

目的:总结原发性肝癌的螺旋CT双期增强表现及诊断价值。方法:回顾性分析我院62例经临床及手术病理证实的原发性肝痛双期增强表现。结果:62例中发现104个病灶。平扫76个病灶呈低密度,28个病灶呈等密度;肝动脉期91个病灶有强化,13个病灶无明显强化;门脉期83个病灶呈低密度或稍低密度,增强呈“快进快出”的变化特点。结论:通过螺旋CT双期扫描能充分反映原发性肝癌的特征,提高对肝痛的检出率和定性诊断的准确率。

Objectiv：To study the manifestations of dual phase enhancement spiral CT scanning in patients with primary hepatocellular carcinoma and their diagnostic value.Methods：The manifestations of dual phase enhancement spiral a CT scanning in 62 cases of primary hepatocellular carcinoma confirmed by surgical operation and pathological examination were analysed retrospectively.Results：104 focuses were found in 62 cases.Among them 76 focuses presented the low density image in plain scanning and 28 focuses presented the isodensity image;91 reinforcement focuses were found in arterial phase,but 13 without obvious reinforcement image;83 focuses exhibited the low density or slight low density image in portal venous phasc,with the variant characteristice of ＂rising and lowering rapidly＂by density.Condusion：Dual phase enhanceent spiral CT scanning possesses a important value in the detection and characterization of primary hepatocellular carcinoma,it can improve the detectable rate and the accurate rate of qualitification.
