3.0TMR-SWI诊断CT阴性急性弥漫性轴索损伤的价值
The value of 3.0 T MR-SWI in diagnosis of diffuse axonal injury with non-lesional CT ifndings
摘要
Abstract
Objective:To investigate the advantages of 3.0 T MR susceptibility weighted imaging (SWI) in diagnosis of diffuse axonal injury (DAI) with non-lesional CT findings.Materials and Methods:Twenty-three patients sufferred from brain trauma with non lesional CT ifndings were highly suspected DAI, and these patients were underwent 3.0 T MR exmination in 3 days after brain trauma, included T1WI, T2WI, FLAIR and SWI sequences. The sensitivity and lesional numbers of theses sequences in detecting lesions were compared, in additon, the relation of lesion numbers in SWI with GCS scores were studied.Results:The lesions concentrated in brain gray matter border zone and deep white matter. Detection rates of TlWI, T2WI, FLAIR and SWI were 23.8%, 32.2%, 46.5% and 83.8%, respectively. Additionally, the number of lesions detected was 31, 68, 103 and 326 respectively on TlWI, T2WI, FLAIR and SWI sequences. The number of lesions detected by SWI was statistical more than conventional sequence (P<0.01).The number of lesions in SWI was negatively correlated markedly with GCS (r=-0.876).Conclusion:SWI can be more completely to display hemorrhagic lesions associated with DAI and be better estimated the condition of patients.关键词
