摘要 目的探讨动态三维超声造影(3D-CEUS)在诊断肝肿瘤中的应用价值。方法选择在我院诊治的51例肝占位患者共55个病灶,造影剂选用SonoVue,依次对病灶进行二维超声、彩色多普勒超声、常规超声造影和动态3D-CEUS检查,并对动态3D-CEUS图像进行处理和分析。观察超声造影的增强方式、不同时期肿瘤血管清晰度及立体感等情况并进行评分。结果本组肝占位病灶动态3D-CEUS显示动脉期肿瘤血管及肿瘤立体感最好,而门脉期较差。动态3D-CEUS诊断肝肿瘤的符合率为92.7%(51/55),其中诊断肝恶性肿瘤的符合率为97.0%(39/40),诊断肝良性病变的符合率为80.0%(12/15)。结论动态3D-CEUS可更直观、动态和有效地显示肝肿瘤血供和空间立体关系,为提高超声诊断肝肿瘤的准确性提供了新的手段。 Objective To evaluate the value of dynamic three-dimensional contrast-enhanced ultrasonography (3D-CEUS) in diagnosis of liver tumor.Methods 3D-CEUS was performed in 51 patients (55 lesions),including 32 primary liver tumors (PLT),6 metastatic liver tumors (MLT),1 epithelioid hemangioendothelioma,1 hepatoblastoma,5 hemangiomas,3 focal nodular hyperplasias(FNH),2 inflammatory pseudotumors,1 adenoma and 4 inflammatory lesions.Contrast media is SonoVue and iU22 was selected with X6-1 volumetric probe.After app...
