Intraoperatively magnetic resonance (MR)-guided neurosurgical operations have been done since 1996, mostly for brain tumors. Several different concepts for intraoperative MRI procedures using low-, middle-, and high-field MR scanners have been reported from pioneering neurosurgical centers. In this article, we present the different solutions used in these centers from a practical point of view. More thoroughly, we present our own concept and experience of 160 craniotomies since 1999 in an operation theater equipped with a low-field (0.23T) scanner, which can be turned on and off during surgery.
自1996年以来，术中磁共振（MR）引导的神经外科手术已经开展，主要针对脑肿瘤。一些领先的神经外科中心报道了使用低场、中场和高场MR扫描仪进行术中MRI检查的几种不同理念。在本文中，我们从实际应用的角度介绍这些中心所采用的不同解决方案。更详细地说，我们介绍了自1999年以来在配备低场（0.23T）扫描仪的手术室中进行160例开颅手术的理念和经验，该扫描仪可在手术过程中开启和关闭。
