目的：通过对头颅快速液体衰减翻转恢复序列与快速自旋回波序列的应用研究，了解其各自的特点及临床价值。材料与方法：65例颅内病变均用两种序列检查。快速FLAIR设置以脑脊液信号低于脑组织为准，即TR／TI／TE：9000／2500/110ms。快速SE：T1W：650／14ms、T2W：5217／110ms。结果：快速FLAJR检出病变1306个，敏感率98％；快速亚检出1164个，敏感率明88%（P＜0．05）。尤其在脑表面、半卵圆区、脑室旁快速FLAIR较快速SE更具优势，并且前者观察病变周围水肿极好。而在基底节区、后顾凹等处FLAIR不如快速SE敏感。结论：FLAIR优点较多但在有的部位不如快速亚，二种序列应互为补充。.
OBJECTIVE: To study the application of rapid fluid decay recovery sequence and rapid spin echo sequence in the skull to understand their respective characteristics and clinical value. Materials and Methods: 65 cases of intracranial lesions were used in two sequences. The fast FLAIR setting is based on a lower cerebrospinal fluid signal than brain tissue, ie TR / TI / TE: 9000/2500 / 110ms. Fast SE: T1W: 650 / 14ms, T2W: 5217 / 110ms. Results: Fast FLAJR detected 1306 lesions, the sensitivity rate was 98%; fast sub-detection of 1164, the sensitivity rate of 88% (P <0.05). Especially in the brain surface, semi-oval zone, fast ventricular septal FLAIR more rapid SE more advantages, and the former observation of the disease around the edema excellent. FLAIR is less sensitive than rapid SE in the basal ganglia, posterior gyrus and so on. CONCLUSIONS: FLAIR has many advantages but is not as fast as in some areas, and both sequences should complement each other. .
