Cardiovascular magnetic resonance (CMR) is gaining ground in guiding electrophysiology (EP)-based ablation procedures of typical atrial flutter and atrial fibrillation, allowing for the avoidance of radiation exposure for patients and operators and reducing the risk of occupational illnesses. CMR allows comprehensive assessment of cardiac anatomy and provides tissue characterization by identifying pathological substrates, such as myocardial scars and edema, identified with the implementation of late gadolinium enhancement and T2-weighted short-tau inversion recovery sequences. Intraprocedural imaging is useful for real-time catheter tracking during the ablation procedure while simultaneously providing visualization of cardiac anatomy. Additionally, CMR facilitates the evaluation of the ablation procedure accuracy by acquiring edema-sensitive sequences, thereby aiding in preventing early complications. This report serves as a primer for radiologists and illustrates the value of CMR in planning and performing the ablation procedure, as well as its role in post-procedural imaging.
心血管磁共振成像（CMR）在指导基于电生理学（EP）的典型心房扑动和心房颤动消融手术方面正逐渐得到应用，可避免患者和操作人员受到辐射暴露，并降低职业疾病风险。CMR能够全面评估心脏解剖结构，并通过识别病理基质（如心肌瘢痕和水肿）来进行组织特征分析，这是通过实施延迟钆增强和T2加权短反转时间反转恢复序列来实现的。术中成像对于消融手术期间的实时导管追踪很有用，同时还能提供心脏解剖结构的可视化。此外，CMR通过获取对水肿敏感的序列，有助于评估消融手术的准确性，从而有助于预防早期并发症。本报告为放射科医生提供了入门指导，并阐述了CMR在规划和实施消融手术中的价值，以及其在术后成像中的作用。
