利用长回波时间（TE）的流体衰减反转恢复脉冲序列对一名志愿者和四名患者进行了脑成像。该序列使用的长反转时间抑制了来自CSF的信号，并且长TE产生非常重的T2加权。脑脊液血流伪影的明显减少和高T2加权使得脑干内的解剖细节得以看到，并在靠近脑脊液的区域产生了高病变对比。在脑梗死、低级别星形细胞瘤患者中，病变比传统的t2加权序列更明显。和双侧瘫痪。
Fluid attenuated inversion recovery pulse sequences with a long echo time (TE) have been used to image the brain in one volunteer and four patients. The long inversion time used with this sequence suppresses the signal from CSF and the long TE produces very heavy T2 weighting. The marked reduction in flow artefact from CSF and the high T2 weighting enabled anatomical detail to be seen within the brain stem and produced high lesion contrast in areas close to CSF. Lesions were demonstrated with greater conspicuity than with conventional T2-weighted sequences in patients with cerebral infarction, low grade astrocytoma. and diplegia.
