目的对比超声造影(CEUS)与增强CT(CECT)在诊断小于3cm肾实性肿瘤的应用价值.方法选取本院2010年1月至2013年1月期间收治的小于3cm肾占位患者54例作为研究对象,分别进行CEUS及CECT检查,观察两种方法的增强强度、增强均匀、假包膜征、增强消退时间,比较其诊断准确率,CEUS利用时间-强度曲线分析软件,对比肾脏占位性病变与病变周围正常肾组织在峰值强度、达峰时间、曲线尖度及曲线下面积的差异.结果 CEUS明显增强42例,肿瘤可见假包膜征31例,呈快进慢出39例,与CECT相比差异有统计学意义(P＜0.05),CEUS准确度92.59％,显著高于CECT(77.78％),差异有统计学意义.结论 CEUS对于小于3cm肾实性肿瘤在增强强度、增强均匀度、假包膜征、增强消退时间与CECT有不同的影像学表现,CEUS诊断小于3cm肾实性肿瘤的敏感度与准确度显著高于CECT.

Objectives To compare the application value of contrast enhanced ultrasound (CEUS) and enhanced CT(CECT) in the diagnosis of renal tumors of less than 3 cm.Methods 54 cases of patients with renal parenchymal tumor admitted in our hospital from January,2010 to January 30,2013 were selected,and all patients were given CEUS and CECT examination.The enhanced intensity,enhanced evenness,pseudocapsule sign,enhance extinction time of the two examination methods were observed,and accuracy rate was compared.Results CEUS significant characteristics showed that 42 cases had significant intensity,31 cases had pseudocapsule signs and 39 cases had appeared enhancement pattern as "fast-in and slow-out",and the differences were statistically significant(P ＜0.05).The accuracy (92.59％) of CEUS were significantly higher than those of CECT (77.78％),and the differences were statistically significant (P ＜ 0.05).Conclusions CEUS has different imaging findings with CECT in aspects of renal tumor enhanced intensity,pseudocapsule sign and enhance extinction.The sensitivity and accuracy of CEUS for kidney cancer diagnosis are higher than those of CECT.
