| 目的 评价FLAIR(液体反转恢复) 序列在颅脑疾病中临床应用价值。方法 对73 例颅脑疾病患者行
快速自旋回波(FSE) 序列及FLAIR 序列扫描。比较FLAIR 序列及T2 像在显示颅脑病变的差异。结果 在73 例颅
脑疾病中,FLAIR 共显示病灶187 个,而T2 加权像只显示126 个。有61 个病灶仅在FLAIR 图像中显示,105 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。 |

| Purpose To evaluate the application of FLAIR in cerebral disease. Methods 73 cases with varied brain disease were studied with FLAIR sequence and FSE. The appearance of FLAIR sequence with T2weighted sequence in the detection of cerebral diseases were analysed. Results There were 126 lesions on T2weighted images while 187 lesions were
detected on FLAIR images (including 61 lesions only could be seen on FLAIR images) . The inter-structure and border of
105 lesions on FLAIR images were showed better than on T2weighted images. Conclusion FLAIR is superior to T2
weighted image for detecting the border extent and inter-structure of cerebral lesions. |
