目的：探讨3.0 T核磁共振FLAIR序列在急性少量自发性蛛网膜下腔出血中的诊断价值。方法回顾分析27例用腰穿结果作为金标准的急性少量自发性蛛网膜下腔出血的磁共振成像液体衰减反转恢复序列（FLAIR序列）表现，并与CT比较。结果3.0 T核磁共振FLAIR序列能很好地显示所有病例的急性少量自发性蛛网膜下腔出血，表现为脑池、脑沟内高信号影。结论3.0 T核磁共振FLAIR序列显示急性蛛网膜下腔出血的敏感性明显优于CT。
目的：探討3.0 T覈磁共振FLAIR序列在急性少量自髮性蛛網膜下腔齣血中的診斷價值。方法迴顧分析27例用腰穿結果作為金標準的急性少量自髮性蛛網膜下腔齣血的磁共振成像液體衰減反轉恢複序列（FLAIR序列）錶現，併與CT比較。結果3.0 T覈磁共振FLAIR序列能很好地顯示所有病例的急性少量自髮性蛛網膜下腔齣血，錶現為腦池、腦溝內高信號影。結論3.0 T覈磁共振FLAIR序列顯示急性蛛網膜下腔齣血的敏感性明顯優于CT。

Objective To evaluate the value of lfuid-inversion recovery (FLAIR) 3.0 TMRI in the diagnosis of acute spontaneous subarachnoid hemorrhage (SAH). Methods 3.0 TMRI with FLAIR sequences was performed in 27 patients with acute spontaneous SAH using the lumbar puncture results as the gold standard. Findings were retrospectively analyzed and compared with that of computed tomography (CT). Results In all patients, acute spontaneous SAH was clearly demonstrated as an area with signal intensity that was higher compared to that of the normal cerebrospinal lfuid in the sulci and cisternae at FLAIR imaging. Conclusion Fast FLAIR sequences is more sensitive than CT scans in the detection of acute SAH, and it can be routinely performed.
