摘　　要：目的　分析FLAIR序列的MRI表现 ,以探讨此技术在低场MRI中的临床应用价值。方法　 32例于常规SE序列及FLAIR序列扫描后行两组图像的对比分析。结果　在低场中FLAIR序列可清晰显示脑室周围 ,皮质表面的微小病灶。对脑室、脑池中病灶的显示也明显优于常规SE序列。与增强SE序列相结合 ,更有利于肿瘤性病变的病变范围、内部结构的显示。Objective MRI Appearences were analyzed after undergoing the examination of fluid attenuated inversion pulse sequences(FLAIR),in order to evaluate the value of the clinical application of FLAIR in low field.Methods 32 cases were analysed comparatively after undergoing the examination of FLAIR sequence and conventional SE sequence.Results The lesions around the ventrical and the surface of cerebral cortex can be showed clearly in FLAIR sequence in low field.Lesions in ventricles and cistens were shown more distinctly in FLAIR sequence than those in conventional SE sequence.With the aid of enhancement scan by conventional SE sequence,the range and the internal structures of the lesions can be manifested clearlier than those in conventional SE sequence.Conclusion In low field the examination of FLAIR sequence is of great value of clinic diagnosis.
