Abstract:
Objective To reveal the transmiting discipline of parameters and define time window for therapy of ischemia penumbra by continuous detection of diffusion tensor imaging(DTI), and evaluate the relations between cortical spinal tracts(CST) and myodynamia by diffusion tensor tract(DTT). Methods 71 patients of cerebral infarction with different timing were imaged with conventional MRI, DWI and DTI, measuring DCavg, FA, RA , 1-VR of different ROI and performing DTT in ten patients. Results DCavg of lesions in different phases were [(0.275?0.022),(0.349?0.019),(0.465?0.023),(0.538?0.035)]?10~ -3mm~2/s, respectively. DCavg value showed tendency of reducing obviously, elevating gradually and false-normalizing (P
