CT 、Conventional MRI Sequences and SWI Diagnosis of Diffuse Axonal Brain Injury in Comparison

Zuo Ling-zhi, Mri Bureau

Abstract

Objective:To investigate the diffuse axonal injury(DAI) of the CT,conventional MRI sequences and susceptibility weighted imaging(SWI) features and diagnostic value.Methods: Retrospective analysis of 42 cases of DAI in patients with image data,analysis,comparison CT,MRI,and SWI signal characteristics and brain lesions display rate.Results: SWI showed lesions up to the most sensitive;brain CT scan,followed by;poor sensitivity of conventional MRI sequences,only some of the lesions appear.Conclusion: CT,MRI,and SWI of DAI early diagnosis,treatment and prognostic evaluation of important reference value,SWI DAI is the most effective diagnostic imaging method of choice.
