Over the last ten years, the number of minimally invasive interventional procedures has been increasing steadily. Magnetic resonance imaging (MRI) is still far less frequently used for image-guided percutaneous procedures or as an intervention method than computed tomography (CT) and ultrasound (US). However, MRI has many advantages, such as lack of ionizing radiation, real-time MR-fluoroscopy placement high resolution, no bone and gas artifacts, the ability to display lesions that are difficult to observe on CT and US visualization of blood vessels without a contrast agent, free selection of imaging planes and in the case of procedures such as thermos or cryoablation it is possible to make an intraprocedural assessment of the process without the application of a contrasting agent (Marini et al. in Diagn Interv Imaging 102: 531-538, 2021; Li et al. in BMC Cancer 21: 366, 2021; Barkhausen et al. in Rofo 189: 611, 2017). Furthermore, in addition to its use in Interventional Radiology, MRI is also becoming a reality in cardiology thanks to the possibility of overcoming all the limits related to the fusion technology used up to now in cardiac ablations (Chubb et al. Arrhythm Electrophysiol Rev 6: 85, 2017). Some suites have been built in Northern Europe and in the United States, but based only on personal experience and industry indication. In our hospital, we have built a new Interventional Magnetic Resonance Imaging Suite (IMRIS), the first in Southern Europe and we have defined what the necessary requirements and equipment were for the safety of the patient and the operator.
在过去的十年中，微创介入性操作的数量一直在稳步增加。与计算机断层扫描 (CT) 和超声 (US) 相比，磁共振成像 (MRI) 用于图像引导经皮操作或作为介入方法的频率仍然要低得多。然而，MRI 具有许多优点，例如没有电离辐射、实时 MR 透视定位高分辨率、没有骨骼和气体伪影、能够显示 CT 和 US 难以观察到的病变、能够在不使用造影剂的情况下可视化血管、可以自由选择成像平面，并且在热疗或冷冻消融等手术中，可以在不使用造影剂的情况下对手术过程进行术中评估 (Marini 等人，Diagn Interv Imaging 102: 531-538, 2021; Li 等人，BMC Cancer 21: 366, 2021; Barkhausen 等人，Rofo 189: 611, 2017)。此外，除了在介入放射学中的应用外，由于克服了迄今为止在心脏消融中使用的融合技术所带来的所有限制，MRI 也正在成为心脏病学中的现实 (Chubb 等人，Arrhythm Electrophysiol Rev 6: 85, 2017)。在北欧和美国已经建造了一些套房，但仅基于个人经验和行业指示。在我们的医院，我们建造了一个新的介入磁共振成像套件 (IMRIS)，这是欧洲南部的第一个套件，我们已经确定了为患者和操作人员的安全所需的必要要求和设备。
