Abstract:
Objective To study the difference between central and peripheral position of contrast gray-scale imaging in rabbit′s liver.Methods Ultrasound contrast agent(UCA) SonoVue TM ( 0.1 ml/kg) was applied respectively in 8 normal rabbits by intravenous bolus injection.Corresponding parameters of the time-intensity curve: time to enhancement(ET),time to peak intensity(PIT),peak signal intensity(PSI),mean transit time(MTT) and area under the curve(AUC) were measured using low mechanical index contrast gray-scale imaging and Wash-in/Wash-out time intensity curve software.Results There was significant difference of parameters of the time-intensity curve between central position and peripheral position of parenchyma ( P
