摘　　要：目的探讨超声造影对直径≤3 cm肝脏局灶性病变的诊断价值。方法回顾性分析69例直径≤3 cm肝局灶性占位病变的临床资料、超声造影表现及病理检查资料,按照患者病灶大小进行分组,探讨不同组超声造影的增强模式是否存在差异。结果超声造影对69例肝脏局灶性病灶的诊断准确率、敏感性、特异性、阳性预测值和阴性预测值分别为94.2%、95.2%、93.8%、87.0%和97.8%。恶性病灶中,直径≤2 cm组超声造影门脉期快速廓清者明显少于>2 cm组(P<0.05)。结论超声造影对直径≤3 cm的肝脏局灶性病灶具有较高的诊断价值。直径≤2 cm肝恶性病灶的超声造影门脉期表现常不典型,需要结合其病史等临床特征进行综合诊断。Objective To explore the diagnostic value of contrast-enhanced ultrasound （CEUS） for small focal liver lesions （FLLs） . Methods The clinical data, CEUS findings, and pathology of 69 patients with small FLLs were retrospectively analyzed. Patients were grouped according to size of FLLs and the perform- ance of CEUS was compared. Results The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of CEUS for the 69 FLLs were 94.2% , 95.2% , 93.8% , 87.0% , and 97.8% , re- spectively. Rate of fast wash-out in portal vein phase was lower in group of diameters ~2 cm than that in group of diameters 〉 2 cm （ P 〈 0. 05 ） . Conclusions CEUS has a high diagnostic value for small FLLs. However, the CEUS findings of malignant lesions smaller than 2 cm are not typical in the portal phase and therefore the di- agnosis should also be based on clinical features.
