The use of magnetic resonance (MR) imaging in the emergency department continues to increase. Although computed tomography is the first-line imaging modality for most head and neck emergencies, MR is superior in some situations and imparts no ionizing radiation. This article provides a symptom-based approach to nontraumatic head and neck pathologic conditions most relevant to emergency head and neck MR imaging, emphasizing relevant anatomy, "do not miss" findings affecting clinical management, and features that may aid differentiation from potential mimics. Essential MR sequences and strategies for obtaining high-quality images when faced with patient motion and other technical challenges are also discussed.
磁共振成像（MR）在急诊科的应用不断增加。虽然计算机断层扫描（CT）是大多数头颈部急症的首选影像学检查方法，但在某些情况下，MR 具有优势，且不会产生电离辐射。本文基于症状介绍了与急诊头颈部 MR 成像最相关的非创伤性头颈部病理情况，重点介绍了相关解剖结构、影响临床管理的“不容错过”的表现以及有助于与潜在类似疾病鉴别的特征。此外，还讨论了在面对患者运动和其他技术挑战时获取高质量图像的基本 MR 序列和策略。
