ABSTRACT
Objective To evaluate the hemodynamic features of VX_2 tumor and peri-neoplastic liver parenchyma with low mechanical index gray-scale contrast enhancement.Methods Ultrasound contrast agent SonoVue((0.1) ml/kg) was applied respectively in 8 VX_2-bearing rabbits by intravenous bolus injection.Corresponding parameters of the time-intensity curvetime to enhancement(ET),time to peak intensity(PIT),peak signal intensity(PSI) and mean transit time(MTT) were measured using low mechanical index contrast gray-scale imaging and Wash-in/Wash-out time-intensity curve software.Results Gray-scale imaging delineated clearly the dynamic enhancement of the VX_2 tumor and the surrounding liver parenchyma.The ET and PIT were definitely earlier,the PSI lower and the MTT absolutely shorter in VX_2 tumors than those in the liver parenchyma.There were significant differences of parameters derived from the time-intensity curve between VX_2 tumors and liver parenchyma(P
