Abstract

Purpose:To evaluate the effectiveness of a high-spatial-resolution susceptibility-weighted imaging(SWI) in detecting hemorrhages in traumatic brain injury(TBI) patients.Methods:Thirty-four patients were divided into two groups,which had mild and moderate-severity by Glasgow coma scale (GCS) scores.All the patients were imaged after injury.SWI,diffusion-tensor imaging(DTI),conventional MR imaging and CT were performed.Results:SWI described 1040 lesions in all,much more than the other image sequences.The number of lesions on SWI was correlated with GCS score(P0.05). Conclusion:SWI depicts more small hemorrhagic lesions than conventional MRI,DTI and CT does,therefore SWI has the potential to improve diagnosis of TBI and evaluate their prognosis.
