ABSTRACT
Objective To investigate the value and dynamic characteristics of diffusion-weighted imaging(DWI)in rabbit liver VX_2 tumor model,with correlation of pathology.Methods Forty New Zealand rabbits were included in the study and VX_2 tumor piece was implanted directly into the liver after laporotomy.Fiffteen had two intrahepatic implants while twenty-five had one implant.DWI was performed on the seventh,fourteenth and twenty-first day after implantation,while routine T_1WI and T_2WI sequences were done on the seventh and fourteenth day.Ten VX_2 tumor samples were studied by pathology.Results The lump detection rates on the seventh day after implantation of DWI,T_1WI and T_2WI were 78.7%(37/47), 10.7%(3/28)and 53.6%(15/28)respectively with statistical significance(x~2=32.61,P
