摘　　要：目的 探讨超声挤压征和（或）浸润征在肝脏良恶性微小病变鉴别诊断中的价值。方法 对164例共178个经穿刺或手术病理证实直径≤2.0 cm的肝内实质性病变进行二维及彩色多普勒血流显像分析,以肿块挤压征和（或）浸润征作为诊断肝脏微小恶性病变的指标。结果 肝脏微小恶性肿瘤挤压征和（或）浸润征检出率（75.24%,79/105）明显高于肝脏良性病变（4.11%,3/73）（P〈0.05）。以有挤压征和（或）浸润征诊断肝脏微小恶性病变的敏感度为75.24%,特异度为95.89%,准确性为83.71%,Kappa值为0.679,ROC曲线下面积为0.846（95%CI=0.786~0.906）。结论 超声挤压征和（或）浸润征在肝脏微小病变的良恶性鉴别诊断中有较大的价值,可为肝脏恶性肿瘤的筛查提供重要的参考。Objective To investigate the value of compression and/or invasion signs in tdtrasonic diagnosis of minimal benign and malignant hepatic tumors. Methods 178 hepatic lesions less than 2. 0 cm in 164 cases proved by puncture or operation pathology were examed by the dimensional uhrasonography and color Doppler flow. The compression and/or invasion signs were regarded as a criterion of malignant hepatic tumors. Results The detection rate of compression and/or invasion signs in the malignant hepatic minimal lesions（75.24% ,79/105 ） was much higher than that in the benign hepatic minimal lesions （4. 11% ,3/73 ） （P 〈 0.05 ）. The sensitivity, specificity and accuracy of the ultrasound in the diagnosis of malignant hepatic minimal tumors were 75.24%, 95.89% and 83.71% respectively. The Kappa was 0. 679, and the area of ROC was 0. 846 （95% CI = 0. 786 - 0. 906）. Conclusion The param- eters of compression and/or invasion signs in ultrasonography can he used for the differentia[ diagnosis of benign and malignant hepatic minimal lesions.
