目的 探讨实时超声造影检查对常规超声不能确诊的肝脏局限性脂肪缺失和脂肪浸润的诊断价值.方法 对94例常规超声检查发现肝脏局限性病变的患者进行实时超声造影检查,其中34例肝脏局限性脂肪缺失和脂肪浸润作为本文研究对象.结果 34例患者经超声造影检查均未显示明显占位性病灶,病灶增强模式与肝实质相同,与肝脏占位性病变超声造影表现明显不同.结论 部分肝脏局部脂肪缺失和脂肪浸润的实时超声造影检查具有典型性表现,对肝脏局部脂肪缺失和脂肪浸润的诊断与鉴别诊断有重要的价值.%Objective To explore the clinical value of real time contrast-enhanced ultrasound in diagnosis of liver localized fatty deletion and fatty infiltration which couldn't be confirmed by conventional ultrasonography. Methods Contrast-enhanced ultrasound was performed on 94 patients with liver localized diseases confirmed by baseline sonography, among them 34 patients with liver localized fatty deletion and fatty infiltration were enrolled. Results Contrast-enhanced ultrasonography didn't show apparent occupancy nidus in 34 patients. Enhancement mode of lesions was the same as liver parenchyma, which was distinctly different from liver occupancy diseases. Conclusion Real time contrast-enhanced ultrasound can display typical signs of liver localized fatty deletion and fatty infiltration and has significant value in diagnosis and differentiating diagnosis of them.
