Abstract:
Objective To evaluate the utility of susceptibility weighted imaging (SWI)in the evaluation of traumatic brain injury (TBI)severities.Methods 20 mild TBI patients,20 moderate TBI patients and 20 severe TBI patients were collected.The involving brain regions,numbers and areas of hemorrhagic lesions detected by SWI were analyzed and the differences of each group were com-pared.The correlation analysis between Glasgow coma scale(GCS)scores and each above parameters were underwent.Results The differences of involving regions’number,lesions’number,lesions’area were statistically significant(P <0.05 ).Severe TBI group got the maximum number of involving regions,lesions,and the largest areas,followed by moderate group and mild group.The GCS were highly negatively correlated with the number of involving regions,number of lesions,areas of lesions detected by SWI.In descending order of relevance:GCS with areas detected by SWI(r=-0.982,P=0.000),the number of lesions detected by SWI(r=-0.941,P=0.000),the number of involving regions detected by SWI(r=-0.900,P=0.000).Conclusion The clinical applications of SWI in diagnosing TBI and evalua-ting the TBI severity is of great significance.
