摘　　要：目的利用超声造影评估正常肾脏皮质与锥体的血流灌注差异。方法对30名健康人共60个肾脏行超声造影(CEU),利用ACQ软件的时间-强度曲线(TIC)分析,观察指标为肾皮质和肾锥体的造影剂到达时间(AT)、达峰时间(TTP)及达峰强度(PI),并计算两者的差异。结果肾皮质的AT、TTP及PI分别为(12.24±3.56)s、(20.67±4.35)s和(25.33±4.17)dB;肾锥体为(14.18±3.34)s、(22.27±3.28)s和(23.03±3.43)dB。两者AT,TTP和PI间差异均有统计学意义(P<0.05)。结论正常肾皮质与肾锥体的超声造影TIC定量参数不同,讨论两者的定量指标,可为临床肾相关疾病的诊断和鉴别诊断提供依据。Objective To evaluate the perfusion of normal renal cortex and pyramids with contrast-enhanced ultrasound （CEU）. Methods CEU was performed on 60 kidneys of 30 healthy subjects and the items of renal cortex and pyramids were analyzed by time-intensity curve （TIC） of ACQ software including arriving time （AT）, time to peak （TTP） and peak intensity （PI）, and the differences of the two groups were calculated. Results The AT, TTP and PI of renal cortex was （12.24±3.56）s, （20.67±4.35）s and （25.33±4.17）dB, respectively, while the AT, TTP and PI of pyramids was （14. 18±3.34）s, （22.27±3.28）s and （23.03±3.34）dB, respectively. There was statistical difference of AT, TTP and PI between renal cortex and pyramids （P〈0.05）. Conclusion The parameters of TIC with CEU are different between normal renal cortex and pyramids. CEU is helpful to provide data for the diagnosis and differential diagnosis of some renal diseases.
