摘要
目的:探讨常规超声及超声造影在肝癌中的诊断及鉴别诊断价值。方法:收集2009年5月至2013年10月在我院进行住院诊治的肝癌患者120例,选择飞利浦IU22进行常规超声检查,选择飞利浦的IU22进行超声造影检查。结果:常规超声检查68例为低回声,20例为强回声,12例为等回声,17例为混合性回声,3例误诊为肝外病变,检出率为97.5%。肝癌组织的AT、TTP、ACT值明显晚于正常肝组织(P<0.05),而BI、PI、MTT与BF值对比差异无明显差异(P>0.05)。Spearman相关分析显示超声造影灌注参数AT、TTP、ACT与肿瘤分化程度呈正向相关性(P<0.05)。结论:常规超声及超声造影在肝癌中的诊断及鉴别都有很好的应用价值,超声造影的应用可反映正常和病变组织的血流灌注情况,从而提高肝癌诊断的准确性。
Objective： To evaluate the diagnosis values of the conventional ultrasound and the contrast-enhanced ultrasonography in hepatocellular carcinoma. Methods： 120 cases with liver cancer who were treated in our hospital from May 2009 to October 2013 were selected and performed the Philips IU22 for routine ultrasound and the contrast enhanced ultrasonography （CEUS）. Results： 68 cases showed hypoechoic, 20 cases were hyperechoic, 12 cases were equal echo, 17 cases were mixed echo, three cases were misdiagnosed the extrahepatic disease, and the detection rate was 97.5 %. The AT, TTP, ACT of the HCC were significantly later than the normal liver tissue （P 〈0.05）, whereas there was no significant difference for the BI, PI, MTT BF values compared （P〉0.05）. Spearman correlation analysis showed that CEUS perfusion parameters AT, TTP, ACT values for the cancer differentiation were positively correlated（P〈0.05）. Conclusion： Conventional ultrasound and Contrast enhanced ultrasonography of liver cancer had better values, and the CEUS can reflect perfusion blood flow in normal and diseased tissue so as to improve the accuracy of diagnosis of liver cancer.
