Diagnostic value of biexponential model of DWI in nontypical hippocampal sclerosis of the youth / 实用放射学杂志

ABSTRACT

Objective To investigate the diagnostic value of biexponential model of DWI in nontypical hippocampal sclerosis (HS) of the youth.Methods DWI with multiple b values were performed on 75 youths with right temporal lobe epilepsy and 20 healthy youths(control group).There were no abnormalities in hippocampus on conventional MRI.11 of 75 patients were proved right HS by surgery and pathology (HS group).Compare the volume of the right hippocampus and their D,D? and f values in HS group and control group.Results There were statistical differences in D and f values between HS group and control group (Z=-3.08,Z=-2.23,P0.05). Conclusion When HS does not have typical appearances on conventional MRI,D and f values can provide help from diffusion and the perfusion of microcirculation aspects.
