Magnetic resonance imaging (MRI) of the pediatric mediastinum is challenging for the practicing radiologist. Many confounding factors add to the complexity of pediatric mediastinal MRI including small patient size, broad spectrum of mediastinal pathologies, motion artifacts and the need for sedation in a significant portion of children. However, with special attention to motion-reduction techniques and knowledge of pediatric-specific considerations, pediatric radiologists can help to provide accurate and timely diagnosis and also prevent multimodality imaging where MRI might be all that is needed. The purpose of this paper was present a practical review of pediatric mediastinal MRI with particular emphasis on diseases where MRI is the primary imaging modality of choice. Additionally, the author addresses those mediastinal processes for which MRI serves as a secondary problem-solving imaging tool.
儿科纵隔磁共振成像（MRI）对放射科医生来说具有挑战性。许多混杂因素增加了儿科纵隔 MRI 的复杂性，包括患者体型小、纵隔病变谱广泛、运动伪影以及需要对大部分儿童进行镇静。然而，通过特别注意减少运动的技术和儿科特定考虑的知识，儿科放射科医生可以帮助提供准确和及时的诊断，并防止多模态成像，其中 MRI 可能是唯一需要的。本文的目的是对儿科纵隔 MRI 进行实用综述，特别强调 MRI 是首选主要成像方式的疾病。此外，作者还介绍了那些 MRI 作为二线解决问题成像工具的纵隔病变。
