Abstract

Objective:To assess the value of susceptibility weihgted imaging (SWI) in diagnosis of diffuse axonal injury. Methods:The MRI data of 23 cases with DAI diagnosed by clinic were analyzed retrospectively. All the patients underwent MRI examination with FALIR sequence and SWI. The detection rates by SWI and FLAIR were compared and characteristics of signal were analyzed. Results:378 diffuse axonal injury lesions were detected by the combination of SWI and FLAIR totally. The sensitivity of SWI and FLAIR was 90.2%,52.1% individually. Conclusion:SWI is more sensitive than FLAIR in diagnosing DAI.
