摘　　要：目的探讨超声造影剂及对比脉冲序列成像技术在肾占位性病变中的应用价值。方法对26例可疑肾占位性病变患者行常规超声检查及实时超声造影。比较造影剂灌注时相、变化规律,并与病理对照。结果超声造影提示肾恶性肿瘤23例,其中皮质期快速强化21例,缓慢强化2例;快速廓清4例,缓慢廓清17例,延迟廓清2例。肾血管平滑肌脂肪瘤3例,其中皮质期周边快速强化1例,周边缓慢强化1例,不均匀强化1例,3例患者周边部均延迟廓清。手术或穿刺病理结果:肾透明细胞癌19例,肾鳞癌1例,肾非霍奇金淋巴瘤2例,肾血管平滑肌脂肪瘤4例。结论超声造影在鉴别肾恶性肿瘤、血管平滑肌脂肪瘤方面有重要的临床使用价值。Objective To explore the value of ultrasound contrast agent and cadence contrast pulse sequencing technology （CPS） in renal occupied lesions. Methods Twenty-six renal occupied lesions underwent conventional and contrast-enhanced ultrasound examinations. The perfusion time and its characteristic of the agent was assessed,and the results were compared with that of pathology. Results In the 26 lesions, 23 lesions were diagnosed as malignant： 21 lesions presented with fast enhancement in cortex phase, 2 with slow enhancement; 4 with quick wash-out, 17 with slow wash-out, 2 with delay wash-out, Three lesions were diagnosed as angiomyolipoma： periphery of the 1 lesions presented with fast enhancement in renal cortex phase, 1 with slow enhancement, 1 with inhomogenous enhancement, all 3 lesions with delay wash-out. Pathology results： transparent cell carcinoma in 19 lesions, squamous cell carcinoma in 1, non-Hodgkin＇s limphoma in 2, angiomyolipoma in 4. Conclusions The contrast-enhanced ultrasound has significant value in the differential diagnosis of the renal occupied lesions.
