Role of Diffusion Weighted Imaging for the Diagnosis of Diffuse Axonal Injury of Brain

HUANG Wen-cai,HAN Fei,TIAN Shi-jun,et al.Department of Radiology,the Wuhan General Hospital of PLA,Wuhan 430070,P.R.China  
Objective:To investigate the value of MR diffusion weighted imaging (DWI) for the diagnosis of diffuse axsonal injury (DAI) of brain.Methods:Of 13 patients having brain trauma,with clinical diagnosis as diffuse axsonal injury (DAI),the magnetic resonance imaging data were retrospectively analyzed.Results:DWI is sensitive in detecting hemorrhagic and edematous lesion in DAI.Especially the detectability of DWI for the small hemorrhagic and edematous lesion is markedly superior than that of spin echo sequence T_1WI and T_2WI.The characteristic manifestations of small hemorrhagic lesion were low signal intensity spot with surrounding edematous halo.After eliminating signal of cerebral spinal fluid,edematous lesion of corpus callosum can be displayed by DWI more clearly.Conclusion:Compared with spin echo sequence,diffusion weighted imaging of MRI is more important in the diagnosis of DAI by its high sensitivity in detecting small brain lesion.
