Abstract:
Objective To investigate the application value of DWI and SWI in the diagnosis of diffuse axonal injury (DAI). Methods MR imaging was performed in 23 patients with clinically diagnosed DAI including the routine se-quences, DWI and SWI sequences.The detected number of lesions was compared among the different sequences.The characteristics of sig|lal and distribution of lesions were analyzed. Results DAI lesions located in the white matter,juncfional zone of cortex and medulla,basal ganglia, corpus eaihsum brain stem arm cerebelhm. The detected number of non-hemorrhagic lesion on DWl was the highest and significantly higher than that on other sequences.The deteced number of hemorrhagic lesion on SWI was the highest and significantly higher than that on other sequences. Conclu-sion Combination of DWl and SWI can improve detection ratio of DAI lesions, provide more image evidence for early clinical diagnosis,so DWI and SWI should be the first and naltilm sequence in the MRI exaafination of DAI detection.
