Abstract:
Objective To investigate the characteristics of leukoaraiosis (LA) and acute lacunar infarction (LI) on diffusion tensor MR imaging (DTI) and evaluate the differential diagnostic value of DTI between LA and acute LI. Methods Twenty-eight LA patients, 11 LI patients and 20healthy aged people were examined by DTI. The mean diffusion coefficient (MD) and fractional anisotropy (FA) values were measured in the lesions and normal appearing white matter (NAWM) of LA, the infarction focus and counterpart in the contralateral hemisphere of LI, and normal white matter of control group. Results The order of MD values was: MD (LA lesions)>MD (LA NAWM)>MD (control group), while the order of FA values was: FA (LA lesions)
