目的：利用磁敏感加权成像（SWI）、液体衰减反转恢复（FLAIR）、CT诊断蛛网膜下腔出血（SAH），进一步比较联合磁共振成像（MRI） SWI/FLAIR与CT比较评估MRI是否优于CT。方法25例经临床证实的蛛网膜下腔出血的患者纳入本研究，所有患者均在发病3 d内进行CT、MRI检查。观察CT及MRI图片，将蛛网膜下腔分为8个区进行分析。结果总共145个区域被诊断为SAH，CT诊断了105个区域（72．4％）， FLAIR诊断了125个区域（86．2％），SWI诊断了137个区域（94.5％），FLAIR联合SWI诊断了135个区域（93．1％）。结论 FLAIR、SWI对于SAH的显示优于CT，FLAIR对颞枕部病灶的显示具有优势，SWI对中央区域的SAH比较敏感，将FLAIR、SWI两者融合，可以互补，能更准确地诊断SHA。

Objective To compare the utility of susceptibility weighted imaging (SWI) with fluid attenuated in-version recovery (FLAIR) and the established diagnostic techniques CT in their detecting capacity of subarachnoid hemorrhage(SAH), and to compare the combined SWI/FLAIR MRI data with CT to evaluate whether MRI is more ac-curate than CT. Methods Twenty-five patients with acute SAH underwent CT and MRI within 3 days after symptom onset. CT and MRI data were analyzed.The anatomaical distribution of SAH was subdivided into 8 subarachnoids. Re-sults 145 subarachnoid regions were confirmed as SAH. CT indentified 105(72.4%), FLAIR identified 125(86.2%), SWI identified 137(94.0%), FLAIR combined SWI identified 135(93.1%) involved regions. Conclusion FLAIR, SWI yields a distinctly higher detection rate for SAH than CT alone. Detecting strength of SWI is higher for central areas, whereas FLAIR shows a better detection rate in peripheral areas, combining SWI and FLAIR are complementary to one another, which will do help for diagnosing SHA.
