摘要
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。
Objective To evaluate the value of fluid-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 fluid 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.
