The 3T ioMRI in Prague is composed of two independent suites: the operating theatre and the 3T MR suite, both of which can and do work independently. They are connected by a double door and a special transportation system. The whole operating table is moved on rails to and from the MR gantry. Anaesthesiological equipment is built from paramagnetic material, which is also moved to and from the MR suite. The integral parts of the multifunctional surgical suite (MFSS) are the neuronavigation system, electrophysiological monitoring, surgical microscope with availability of indocyanin green angiography and fluorescence-guided glioma resection technique and endoscopy equipment. The operating theatre is equipped in a normal fashion with the exception of a head holder that is paramagnetic. MR radiologist and MR assistants are alerted approximately 30 min before the requested intraoperative and out-patient service is interrupted to clean the MR suite. The ioMRI takes 15-20 min and immediately after the door closes the out patient activity is resumed. Intraoperative MR was performed in 332 surgeries in the first 17 months of operation. The most frequent indications were pituitary adenomas, followed by gliomas. Other indications were less frequent and included meningiomas, cavernomas, aneurysms, epilepsy surgery, intramedullary lesions, non-pituitary sellar lesions, metastases and various other surgeries. In 332 cases no technical or medical complication connected with ioMRI was encountered.
布拉格的3T术中磁共振成像（ioMRI）由两个独立的区域组成：手术室和3T磁共振成像区域，二者均可独立运行且确实在独立工作。它们通过双扇门和一个特殊的运输系统相连。整个手术台通过轨道在磁共振成像机架之间来回移动。麻醉设备由顺磁性材料制成，也可在手术室和磁共振成像区域之间来回移动。多功能手术套件（MFSS）的组成部分包括神经导航系统、电生理监测设备、具备吲哚菁绿血管造影功能和荧光引导下胶质瘤切除技术的手术显微镜以及内窥镜设备。手术室除了头部固定器是顺磁性的之外，其他设备均为常规配备。在请求的术中及门诊服务中断前约30分钟，磁共振成像放射科医生和磁共振成像助手会收到通知，以便清理磁共振成像区域。ioMRI检查耗时15 - 20分钟，门关闭后门诊活动立即恢复。在投入使用的前17个月里，共进行了332例术中磁共振成像检查。最常见的适应症是垂体腺瘤，其次是胶质瘤。其他适应症较少见，包括脑膜瘤、海绵状血管瘤、动脉瘤、癫痫手术、髓内病变、非垂体鞍区病变、转移瘤以及各种其他手术。在332例病例中，未出现与ioMRI相关的技术或医疗并发症。
