Abstract:
Objective To evaluate the clinical application of fast fluid-attenuated inversion recovery(FLAIR) pulse sequence in MRI study of ADE.Methods Thirty cases with ADE were studied with fast FLAIR sequence and T 2 weighted spinecho sequence.The results were compared in terms of image quality.Results We found the fast-FLAIR could suppress CSF signal effectively,and more lesions were displayed on FLAIR images than on turbo SE T 2-weighted images.The extent of the lesions and the contrast between lesions and normal brain tissue were demonstrated better with fast-FLAIR sequence.Conclusion The lesions in ADE are demonstrated on fast-FLAIR sequence better than on turbo SE T 2 weighted sequence and FAST-flair could be a complementing modality to display lesions in ADE.
