摘要 126例颅脑肿瘤同时行快速液体反转回复序列(Fast FLAIR)成像和常规FSET_2W成像。通过比较分析两者显示病变的能力,探讨FLIAR对颅脑肿瘤的诊断价值。结果显示FLAIR序列MRI较T_2WI有更高的对比度,在显示病变的部位、大小、轮廓、范围和数目方面具有更好的敏感性。作者认为,快速FLAIR序列可作为常规SE T_2WI的必要补充,建议列为颅脑肿瘤MRI检查的常规扫描。 126 patients with intracranial tumors were examined with fast fluid-attenuated inversion-recovery (FLAIR) and routine MR imaging including fast spin-echo T2WI and T2WI simultaneously. The value of FLAIR in the diagnosis of intracranial tumors were investigated by comparising with SE T2WI. The contrast between lesions and the background was revealed better on the FLAIR images than that on T2WI. So did the detectabilities of the location, size, contour, extent and numbers of the lesions. We concluded that fast FLAIR pulse sequence should be listed on the routine MR imaging as a complementing modality of FSE T2WI.
