Diffusion tenser imaging of motor aphasia in patients with cerebral infarction

Objective To explore the changes of white matter in language function area in patients with motor aphasia after cerebral infarction by using diffusion tenser imaging(DTI)technique.Methods Eleven patients with motor aphasia after cerebral infarction(observation group)and sixteen healthy right-handed volunteers(control group)were detected fractional anisotropy(FA)and apparent diffusion coefficient(ADC)with DTI technique.Results There were no significant differences in FA and ADC values between patients with left hemisphere language(0.396±0.033,0.725±0.083)and with right hemisphere language(0.404±0.035,0.751±0.094)in control group(P0.05).FA was lower in the patients with left hemisphere language in observation group(0.327±0.075)than that in control group(P0.05).There was no significant difference in ADC in patients with left hemisphere language between observation group(0.741±0.106)and control group(P0.05).FA was lower in infarction area(0.310±0.023)than that in the side mirror area(0.416±0.038)(P0.05),and there was no significant difference in ADC between infarction area(0.752±0.103)and the side mirror area(0.791±0.097)in observation group(P0.05).ConclusionIn patients with motor aphasia after cerebral infarction,FA decreases in language function area no matter infarction occurs or not,and the change of ADC value is not obvious.
