【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。更多还原

【Abstract】 Objective To investigate the value of compression and /or invasion signs in ultrasonic 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 ultrasonography 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 parameters of compression and / or invasion signs in ultrasonography can be used for the differential diagnosis of benign and malignant hepatic minimal lesions.更多还原
