Abstract:
Objective To investigate clinical usefulness of intracranial lesions in pre-and post-operation by functional MRI with blood oxygen level dependent(BOLD)technique.Methods Common MRI and Motor hand area functional MRI examinations were performed in 45 patients (fMRI group)with intracranial lesions adjacent to the motor cortex before and after operation. As contrast group, 20 patients with occupying position lesions were made a routine MRI examination without fMRI before surgery. A 1.5 T signa super conducting system was employment (GE company ,America). Results The focal transactivation domain of cerebration was seen on fMRI in all cases of fMRI group. The cortical motor hand area shown displacement in 22 cases with abnormal size and shape and found not displacement in 23 cases. The distribution of transactivation domain was not changed in different disease . There was positive correlation between the distance from lesions to the domains and myodynamia in preoperation(r=0.553,P0.05). Our data indicated that there was negative correlation between the distance and the difference of myodynamia (r=-0.570,P
