Abstract:
Objective To explore the diagnostic value of parametric imaging of contrast-enhanced ultrasound(CEUS) on recurrent hepatocellular carcinoma after liver transplantation.Methods CEUS images of 41 recurrent hepatocellular carcinoma after liver transplantation was analyzed by Sonoliver CAP software.The color code image,curve image and quantitative parameter of DVP of each recurrence lesion was recorded,then typed and analyzed statistically.Results The DVP patterns were classified into 3 types,they were washed out types,non-washed out types and negative types.The washed out types,non-washed out types and negative types on color code image and curve image of DVP were 70.73％ (29/41),24.39％ (10/41),4.88％ (2/41) and 63.41％(26/41),34.15％ (14/41) and 2.44％ (1/41) respectively.The maximum intensity,rise time,time to peak of the recurrence lesion and the surrounding liver parenchyma were (149.98± 65.29) ％,(12.32 ± 5.83)s,(13.01 ±6.07)s and (100±0.00)％,(26.10± 10.81)s,(29.69± 11.60)s respectively,and showed statistical differences (P ＜0.05).Conclusions The difference of blood perfusion between the recurrence lesion and the surrounding liver parenchyma can be displayed by DVP's dynamic,direct and quantitative imaging,which can be used to provide valuable information about the detection of intrahepatic lesion of recurrence after liver transplantation.
