【摘要】 目的评价液体抑制反转恢复 (FLAIR)序列在颅脑疾病中临床应用价值。方法对 6 3例颅脑疾病患者行常规FSET1、T2序列及FLAIR序列扫描。比较这些序列在显示颅脑病变的差异。结果在 6 3例颅脑疾病中 ,FLAIR像共显示病灶 14 7个 ,而T2加权像只显示 10 6个。有 4 1个病灶仅在FLAIR图像中显示 ,95个病灶的内部结构、边界在FLAIR像较T2 像显示清晰。结论FLAIR像显示颅脑中邻近脑沟、脑室旁 ,脑室及脑池内等部位病变的边界、大小、范围及内部结构优于T2 加权像。更多还原

【Abstract】 Objective To evaluate the application of flow attenuated inversion recovery( FLAIR)sequence in cerebral disease.Methods 63 cases with varied brain disease were studied with FLAIR sequence and FSE MR imaging. The images of these sequences in the detection of cerebral diseases were analysed and compared.Results There were 106 lesions on T 2 -weighted images while 147 lesions were detected on FLAIR images (including 41 lesions only could be seen on FLAIR images).The inter-structure and border of 95 lesions on FLAIR images were showed better than on T 2 -weighted images.Conclusion FLAIR is superior to T 2 -weighted image for detecting the border extent and inter-structure of cerebral lesions.更多还原
