Objective To assess normal liver contrast color enhancement using harmonic power imaging (HPI), comparative studies between HPI and color Doppler flow imaging (CDFI) were performed.
目的评价谐波能量显像（HPI）在正常肝脏声学造影中的造影增强效果，并与彩色多普勒血流显像（CDFI）进行对比。
Results Compared with dynamic CT, 93.9% (31/33) of tumors before treatment were demonstrated as enhancement on both intermittent harmonic power Doppler imaging and gray-scale harmonic subtraction.
结果以动态增强CT结果为金标准，治疗前33个肝癌结节，超声造影增强的阳性率为93.9%（ 31/ 33） ；
Objective To characterize the dynamic contrast enhancement in focal hepatic lesions with pulse inversion harmonic (PIH) ultrasonographic imaging.
