      【摘要】 目的 对比超声造影与增强CT在肝脏局灶性病变中的诊断价值。方法 选择2012年6月至2014
年4月间我院肝病科诊治的肝脏局灶性占位患者60例，其中肝脏恶性病变30例，均为肝细胞肝癌，肝脏良性病变
30例，均接受强化CT及超声造影检查。分析肝脏占位的超声造影及CT强化特征，测量并分析肝脏良恶性病变
超声造影参数及动态血管模式(DVP)曲线特征，比较超声造影及CT强化对肝脏占位诊断情况。结果 肝脏良性
病变者超声造影参数上升时间(RT)、达峰值时间(TTP)、平均渡越时间(mTT)均明显高于肝脏恶性病变者，峰值强
度(PI)明显低于肝脏恶性病变者，差异均具有统计学意义(P<0.05)；肝细胞肝癌Ⅰ型DVP曲线比例最高，而肝脏
良性病变以Ⅱ~Ⅲ型曲线多见；超声造影对肝脏占位诊断敏感性及诊断符合率均明显高于增强CT，差异均具有
统计学意义(P<0.05)。结论 与增强CT比较，超声造影对肝脏局灶性病变诊断符合率高，且能够提供丰富的诊
断信息。

【Abstract】 Objective To compare the value of contrast-enhanced ultrasonography and contrast-enhanced
CT in the diagnosis of focal liver lesions. Methods Sixty patients with focal liver lesions in Department of General
Surgery in our hospital from June 2012 to April 2014 were enrolled in the study, including 30 patients of malignant liv-
er lesions and 30 patients with benign liver lesions. The patients all underwent contrast-enhanced ultrasonography and
contrast-enhanced CT. The ultrasonographic and enhanced CT features of focal liver lesions were analyzed. The con-
trast-enhanced ultrasonographic parameters and the characteristics of DVP curve of malignant and benign liver lesions
were measured and analyzed. The value of contrast-enhanced ultrasonography and contrast-enhanced CT in the diagno-
sis of focal liver lesions were compared. Results Rise time (RT), time to peak (TTP) and mean transfer time (mTT)
of the liver benign lesions of contrast-enhanced ultrasonography were significantly higher than that of malignant liver
lesions, while peak intensity (PI) was significantly lower than that of malignant liver lesions (P<0.05). Hepatocellular
carcinoma mostly showed typeⅠ DVP curve, and benign liver lesions mostly showed typeⅡ~Ⅲ DVP curve. The di-
agnostic sensitivity and diagnosis coincidence rate of contrast-enhanced ultrasonography for focal liver lesions were
significantly higher than those of CT (P<0.05). Conclusion Compared with contrast-enhanced CT, contrast-en-
hanced ultrasonography has higher diagnosis coincidence rate for focal hepatic lesions, and it can provide abundant di-
agnostic information.
