评价 MRI的液体衰减反转恢复序列 ( FLAIR)在颅内出血中的应用价值。方法　回顾性分析 2 8例颅内出血患者 MRI常规序列及 FLAIR序列图像表现。其中脑内出血 2 3例 ,合并蛛网膜下腔出血 1 2例 ,合并脑室出血 4例 ;硬膜下出血 3例 ;肿瘤出血 2例。全部患者均在发病后 3～ 1 0天内行 MR检查。结果　硬膜下出血 ,MR常规扫描及 FLAIR序列均可清晰显示 ,两者之间无显著差异 ;在鉴别亚急性期脑实质内出血是否为肿瘤出血时 ,FLAIR序列具有一定诊断价值 (血肿周围低信号环 ) ;FLAIR序列在显示急性蛛网膜下腔出血和脑室出血中明显优于常规 SE序列。结论　 FLAIR序列在显示急性蛛网膜下腔出血和脑室出血中 ,具有可靠的诊断价值 ;对确定肿瘤出血有一定的参考价值 To evaluate the value of MRI FLAIR in intracranial hemorrhage. Methods A retrospective analysis of 28 cases of intracranial hemorrhage MRI sequences and FLAIR sequence images. Including intracerebral hemorrhage in 23 cases, merged with subarachnoid hemorrhage in 12 cases, merger ventricular hemorrhage in 4 cases; 3 cases of subdural hemorrhage; 2 cases of tumor hemorrhage. All patients underwent MR examination within 3 to 10 days after onset. Results Subdural hemorrhage, MR routine scan and FLAIR sequence were all clearly demonstrated without any significant difference between the two. FLAIR sequence was of diagnostic value in discriminating subacute intracerebral hemorrhage from tumor hemorrhage (low signal around hematoma Loop); the FLAIR sequence was significantly superior to the conventional SE sequence in displaying acute subarachnoid hemorrhage and ventricular hemorrhage. Conclusion The FLAIR sequence has a reliable diagnostic value in displaying acute subarachnoid hemorrhage and intraventricular hemorrhage. It is of certain reference value to determine the tumor hemorrhage
