SWI对弥漫性轴索损伤的诊断价值
The application value of 3.0 T MR susceptibility weighted imaging in diffuse axonal injury
摘要
Abstract
Objective:To explore the clinic application value of 3.0 T MR susceptibility weighted imaging (SWI) in the di-agnosis of patients with diffuse axonal injury. Methods:35 cases of suspected diffuse axonal injury patients were collected and analyzed by 3.0 T MRI examination,including conventional TSE sequence,fluid-attenuated inversion recovery sequence (Flair) and SWI sequence. The characteristics of lesions in different imaging techniques were observed and compared to analyze the clinic application value of SWI. Results:302 lesions were detected from 35 cases with 2 cases of single lesion and 33 of mul-tiple. Conventional T1WI had 114 lesions detected,with 93 pure edema lesion and 21 lesions of edema concurrent with hemor-rhagic;T2WI had 231 lesions detected,with 182 pure edema lesion and 49 lesions of edema concurrent with hemorrhagic;FLAIR sequence had 268 lesions detected,with 203 pure edema lesions and 65 lesions of edema concurrent with hemorrhage. While SWI sequence discovered 302 lesions,with 40 pure edema lesion and 262 edema concurrent with hemorrhagic lesion. Compared with conventional T1WI,T2WI and FLAIR sequences,SWI had higher sensitivity in detecting lesions and hemorrhagic lesions,and the difference was statistically significant (P<0.05). Conclusion:SWI is effective in the examination of patients with diffuse axonal injuries caused by traumatism,especially sensitive to the diagnosis of hemorrhagic and non-hemorrhagic lesions,so it is significant in the early clinic diagnosis and treatment of patients.关键词
