MRI FLAIR对脑挫裂伤的诊断价值

目的:探讨MRI FLAIR序列对脑挫裂伤的诊断价值。方法:回顾性分析22例脑挫裂伤的MR表现。结果:脑挫裂伤病变单发性3例,多发性19例。发生于颞叶2例,顶叶1例,双额叶3例,颞、顶叶3例,额、顶叶3例,额、颞、顶、枕复合伤10例。MRI表现为出血性改变8例,FLAIR序列表现为混杂高信号或低信号的病灶;非出血性病灶14例,FLAIR序列表现为高信号。常规T2WI发现病灶共58处,FLAIR上共发现病灶77处。结论:FLAIR序列对脑挫裂伤病变显示优于FSE序列T2WI,有很高的临床使用价值。

The diagnostic value of MRI FLAIR in cerebral contusion and laceration

Objective:To investigate the diagnostic value of FLAIR in cerebral contusion and laceration.Methods:The clinical MRI data of 22 patients with cerebral contusion and laceration were retrospectively analyzed.Results:3 patients showed solitary lesion,and 19 patients multiple lesions.The 2 cases were in temporal lobes,1 case in parietal lobe,3 cases in double frontal lobes,3 cases in parietal and temporal lobes,3 cases in frontal and parietal lobes,10 cases of compound injury in frontal,parietal,temporal and occipital lobes.8 cases with hemorrhagic lesions showed the combined high signal or the low signal in FLAIR,14 cases with non-hemorrhagic lesions showed the high signal in FLAIR.There were 58 lesions confirmed by T_2WI,77 lesions confirmed by FLAIR.Conclusion:FLAIR sequence is superior to FSE T_2 in detection of cerebral contusion and laceration.FLAIR has been an important value in diagnosing cerebral contusion and laceration.
