| 摘 要： | 目的：探讨快速ＦＬＡＩＲ序列ＭＲＩ在脑梗塞诊断中的应用价值。材料和方法：对３５例脑梗塞患者行颅脑常规ＳＥ序列和快速ＦＬＡＩＲ序列ＭＲＩ检查，并对比分析常规Ｔ２Ｗ与ＦＬＡＩＲ成像对病变的显示能力。结果：ＭＲＩ共发现５０个脑梗塞灶。除２个病灶外，４８个病灶ＦＬＡＩＲ成像较ＳＥ序列Ｔ２Ｗ成像显示更为清晰明确，其中３个皮层／皮层下病灶和１个脑室旁病灶仅为ＦＬＡＩＲ成像显示；ＳＥ序列Ｔ２Ｗ与ＦＬＡＩＲ成像显

| Abstract: | Purpose:To evaluate the repid fluid-attenuated inversion recovery(FLAIR)sequence MR imaging in diagnosing of cerebral infarction.Materials and Methods:35 patients with cerebral infarction were studied with conventional SE and rapid FLAIR sequences,for comparin the detectabilities of lesions.Results:50 infartionfoci were identified with MRI in 35 patients.The conspicuous detectability of the lesion was superior on FLAIR inages in 48 of the lesions,and othes 3 cortical and 1 periventrical infartions,were only be identified on FLAIR images lesions size were compared on T2W and FLAIR images;11 chronic infarctions menifested hypointensity on FLAIR images.Conclusion:FLAIR sequence offers advantages for the detection of cerebral infartions,especially in cortical and periventrical sites;and also helpful to differentiate the acute infartions from chronic ones. |
