Abstract:
Objective To investigate the conventional ultrasound characteristics of VX2 tumors in fatty liver and normal liver of rabbits,furthermore,to analysis the blood flow characteristics of them with contrast-enhanced ultrasound (CEUS).Methods Rabbit model of fatty liver and normal liver with implanted VX2 tumors were established,and examined using conventional and CEUS.QontraXt quantitative software of CEUS was used.Results The fatty liver models with 20 VX2 tumors and normal liver models with 23 VX2 tumors were successfully developed in rabbits.In conventional ultrasonography,hyperechoic VX2 tumor lesions in fatty liver were far less than them in normal liver (P =0.008).No significant difference was found in iso-echoic and hypoechoic VX2 tumor lesions between two groups (P ＞ 0.05).Compared with normal liver parenchyma,arrival time of fatty liver parenchyma was later,peak intensity was lower (P ＜0.05).There was no significant difference in arrival time,peak intensity,sharpness,area under curve between the VX2 tumors of normal liver and fatty liver (P ＞ 0.05).Conclusions There is a significant difference characteristic in conventional ultrasonography between VX2 tumors in fatty liver and normal liver.Fatty liver blood perfusion effects are lower than normal liver in CEUS.Quantitative parameters of CEUS are more objective and accurate for hemodynamic of VX2 tumors and fatty liver.
