Abstract:
Objective To evaluate the possibility and scan the protocol of diffusion tensor imaging(DTI) in rabbit VX2 liver tumor models.Methods MRI and DTI images were obtained from 16 rabbit VX2 liver tumor models and 4 rabbit control liver models.Average diffusion coefficient(ADC),fractional anisotropy(FA) of tumors and control livers were estimated and compared with the changing rules(b value=100,600,1000 mm2/s).Results ADC of tumors had a descending trend and FA of tumors had an increasing trend compared with control livers.The fluctuations of ADC and FA of tumors had a descending trend(P
