| 摘 要： | 目的 探讨FLAIR技术在散发性脑炎MR成像中的应用。方法 对 3 0例散发性脑炎行快速FLAIR及T2 WI的MR检查 ,并比较所得的图像质量。结果 快速FLAIR技术与快速自旋回波T2 WI比较 ,能增加病灶与正常组织间的对比 ,从而能更敏感地发现病变。结论 快速FLAIR技术对散发性脑炎病变的显示优于快速自旋回波的T2 WI序列 ,可作为本病常规MR检查的补充手段 |

| 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. |
