心脏磁共振在指导复杂的心脏手术方面很有吸引力，因为它是无电离辐射的，并且提供了灵活的软组织对比。介入性心脏磁共振有望改进现有程序，并使复杂心律失常以及先天性和结构性心脏病的新程序成为可能。指导侵入性手术需要更快的图像采集、重建和分析，以及直观的术中成像数据显示。标准的心脏MR技术，如3D解剖成像、心脏功能和血流、参数标测和晚期Gd增强，可用于在不同的手术阶段收集有价值的临床数据。快速的术中图像分析可以提取和突出有关介入靶点和结果的关键信息。在某些情况下，实时交互成像用于向干预者提供连续的图像流显示，以用于动态设备导航。或者，根据通过快速分割和配准生成的主要心脏结构的路线图来导航设备。介入设备可以通过专门的成像方法在整个过程中进行可视化和跟踪。在临床环境中，先进的成像必须与其他临床工具和患者数据相结合。为了执行这些复杂的过程，介入性心脏磁共振依赖于定制的设备，如交互式成像环境、室内图像显示、音频通信、血流动力学监测和记录系统以及电解剖标测和消融系统。在这种复杂的环境中运作需要协调和规划。本文将对MRI引导的心脏介入治疗中使用的成像技术进行综述。具体地说，这篇综述将概述临床靶点、标准图像采集和分析工具，以及将这些工具整合到临床工作流程中。
Cardiac MR is appealing to guide complex cardiac procedures because it is ionizing radiation free and offers flexible soft tissue contrast. Interventional cardiac MR promises to improve existing procedures and enable new ones for complex arrhythmias, as well as congenital and structural heart disease. Guiding invasive procedures demands faster image acquisition, reconstruction and analysis, as well as intuitive intra-procedural display of imaging data. Standard cardiac MR techniques such as 3D anatomical imaging, cardiac function and flow, parameter mapping and late-gadolinium enhancement can be used to gather valuable clinical data at various procedural stages. Rapid intraprocedural image analysis can extract and highlight critical information about interventional targets and outcomes. In some cases, real-time interactive imaging is used to provide a continuous stream of images displayed to interventionalists for dynamic device navigation. Alternatively, devices are navigated relative to a roadmap of major cardiac structures generated through fast segmentation and registration. Interventional devices can be visualized and tracked throughout a procedure with specialized imaging methods. In a clinical setting, advanced imaging must be integrated with other clinical tools and patient data. In order to perform these complex procedures, interventional cardiac MR relies on customized equipment, such as interactive imaging environments, in-room image display, audio communication, hemodynamic monitoring and recording systems, and electroanatomical mapping and ablation systems. Operating in this sophisticated environment requires coordination and planning. This review will provide an overview of the imaging technology used in MRI-guided cardiac interventions. Specifically, this review will outline clinical targets, standard image acquisition and analysis tools, and the integration of these tools into clinical workflow.
