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.
