Abstract:
Objective To reveal the transmiting discipline of parameters and define therapy time window of ischemia penumbra by continuous detection of diffusion tensor imaging(DTI) o Methods 35 patients with acute cerebral infarction in different phases were imaged with conventional DWI and DTI.To measure DCavg,FA,RA,1-VR,ADC in different regions of interest (ROI).Results Change in DCavg had tendency which appear reduced obviously,elevated,renormalized,increased.FA/RA/1-VR of lesions elevated in hyperacute stroke and unrecovered declined acute to sub-acute stroke.Difference of DCavg,FA,RA,1-VR between central and periphral parts of lesions were significant in hyperacute and acute stroke.ADC of lesions were significant in hyperacute and acute stroke.Difference of FA between central and peripheral parts of lesions were significant in acute stroke(P ＜ 0.01).Difference of ADC,DCavg between central and peripheral parts of lesions were significant in acute and subacute stroke(P ＜ 0.01).Conclusion It had characteristic discipline in changes of DCavg,FA,RA,1-VR,ADC,The peripheral parts of lesions in hyperacute and acute stroke maybe ischemia penumbra,DTI has important practical value for clinical.
