     【摘要】目的探讨超声造影二次谐波成像技术在肝血管瘤中的应用。方法 23例肝血管瘤患者经肘静脉团注SonoVue,采用超声造影二次谐波成像技术,实时观察注射造影剂后病灶增强特征。结果经超声造影后，23个病灶在动脉相均出现增强，且20个(87%)表现为周边向心型，2个(8.7%)为中央扩散型，1个(4.3%)为整体型增强特征。13个>3 cm的病灶，门脉相及延迟相持续增强，为周边向心型；≤3 cm的病灶中7个为周边向心型，2个为中央扩散型，1个为整体型增强。结论 SonoVue超声造影二次谐波成像技术能动态显示病灶增强特征，有助于肝血管瘤的准确诊断。

    【Abstract】 Objective To investigate the application of SonoVuecontrastenhanced ultrasound and second harmonic imaging in liver hemangioma.Methods SonoVue was bolus injected via peripheral vein in 23 patients with liver hemangioma.The technique of contrastenhanced ultrasound and second harmonic imaging was used. The enhancement features of lesions were observed after injection of SonoVue.Results All hemangiomas enhanced after contrastenhanced ultrasound and 20 (87%) of them showed periphery to center enhancement pattern,2(8.7%) showed centertoperiphery enhancement pattern,1(4.3%) revealed homogenwous enhancement pattern.The lesions were persistently enhanced at portal phase and late phase.13 lesions diameter >3 cm showed peripherytocenter enhancement pattern.10 lesions diameter ≤3 cm showed 7 peripherytocenter,2 center toperiphery and 1 revealed homogeneous enhancement pattern.Conclusion The SonoVue contrastenhanced ultrasound and second harmonic imaging can show dynamic enhancement features of liver hemangiomas,which is helpful to the accurate diagnosis. ......
