在30例有蛛网膜下腔出血临床证据的患者中，比较了磁共振（MR）成像与计算机断层扫描（CT）扫描的可行性、安全性和诊断价值。与CT相比，MR成像更容易识别蛛网膜下腔出血，并且可以获得更多关于出血部位和来源的信息。只要使用非铁磁夹，并提供全面的监测和心肺支持，磁共振成像在术前和术后都可以安全使用。术后研究表明，与CT扫描相比，金属植入物和患者移动引起的伪影对MR图像的影响较小。
The feasibility, safety, and diagnostic value of magnetic resonance (MR) imaging versus computerized tomography (CT) scanning were compared in 30 patients with clinical evidence of subarachnoid hemorrhage. Subarachnoid blood was identified more often and more information was available about the site and source of the hemorrhage on MR imaging than on CT. Magnetic resonance imaging could be used safely both before and after the operation, provided that nonferromagnetic clips were used and that comprehensive monitoring and cardiorespiratory support were available. Postoperative studies showed that artifacts from metallic implants and from patient movement caused less image degradation on MR images than on CT scans.
