肾脏占位性病变的实时超声造影特征

The Features of Renal Masses in Real-Time Contrast-Enhanced Sonographic Imaging

目的:探讨肾脏占位性病变的超声造影特征。材料和方法:对126例常规超声诊断为肾脏占位病变或可疑肾脏占位病变的患者,使用声诺维造影剂进行超声造影检查,将结果与病理对比。结果:肾透明细胞癌造影增强模式多表现为快速增强、快速减退;肾血管平滑肌脂肪瘤造影增强模式多表现为延迟增强、延迟减退;肾囊肿造影模式表现为造影剂灌注缺如区周边清晰光滑,囊肿内无造影剂显示。结论:肾透明细胞癌、肾血管平滑肌脂肪瘤、肾囊肿超声造影时相、增强模式具有一定的特征,有助于鉴别诊断。

Purpose： Contrast-enhanced ultrasound imaging is able to provide information on the nature of soft tissue lesions. The value of real-time contrast-enhanced sonographic imaging in renal space-occupying lesions was investigated in this study. Materials and Methods：A total of 126 patients suspected of renal mass（es） by routine ultrasound underwent real-time gray-scale contrast-enhanced sonographic imaging using SonoVue. The results were compared with pathologic results. Results： The enhancement time and patterns were found different among various renal lesions. An early arterial enhancement and a fast wash-out were typically presented in renal clear cell carcinoma. Otherwise, renal angiomyolipoma had much delayed contrast wash-in and wash-out. No enhancement found in feature of renal cysts. Conclusion： The real-time contrast-enhanced ultrasonography is sensitive and effective in the diagnosis of renal masses.
