摘　　要：目的评价实时超声造影对脂肪肝背景下肝脏局灶性病变(FLL)的诊断价值。方法采用低机械指数实时谐波超声造影技术,对常规超声不能确诊的脂肪肝背景下的69个局灶性病变进行了超声造影检查,将超声造影结果同增强CT、增强MRI及病理诊断进行对比,分析超声造影检查的诊断价值。结果超声造影检查后,1例肝紫癜被误诊,1例肝血管瘤被误诊。超声造影对恶性FLL的敏感性、特异性、诊断符合率分别为100%(9/9)、96.7%(58/60)、97.1%(67/69)。结论超声造影可作为脂肪肝背景下FLL鉴别诊断的重要方法。Objective To evaluate the value of contrast-enhanced uhrasound（CEUS） in the differential diagnosis of focal liver lesions（FLLs） under the background of fatty liver. Methods A total of 69 FLLs on ultrasound were observed and analyzed with real-time harmonic ultrasonographic imaging under a low mechanical index CEUS. The final diagnosis was based on interpreting of all examinations with enhanced helical computed tomography（CT）, magnetic resonance imaging（MRI）, and histologic data. The diagnostic efficiency was analyzed. Results After CEUS,one case of hepatic peliosis and 1 case of hepatic hemangiomas were misdiagnosed. The diagnostic sensitivity, specificity and accuracy were 100% （9/9）, 96. 7% （58/60）, and 97.1%（67/69） ,respectively. Conclusion CEUS can be used as an important tool for differential diagnosis of FLL under the background of fatty liver.
