There is often considerable phenotypic overlap in hypertrophic and infiltrative cardiomyopathies. This overlap creates difficulties, when using routine imaging modalities, in arriving at a conclusive diagnosis. Cardiovascular magnetic resonance (CMR) can make diagnosis easier and more certain. Used with gadolinium contrast agent for tissue characterization, CMR offers a superior field of view and temporal resolution, enabling clinicians to make more confident assessments of etiology. CMR may also be a useful modality for stratifying risk and monitoring treatment responses over time in patients with hypertrophic or infiltrative cardiomyopathies. This article highlights the role of CMR in the assessment and, if relevant, the risk stratification of hypertrophic and infiltrative cardiomyopathies.
肥厚型心肌病和浸润性心肌病通常存在相当大的表型重叠。这种重叠在使用常规成像方式时，给得出确定性诊断带来了困难。心血管磁共振成像（CMR）可以使诊断更容易且更确定。CMR与钆对比剂一起用于组织特征分析，提供了优越的视野和时间分辨率，使临床医生能够对病因做出更有信心的评估。CMR对于肥厚型或浸润性心肌病患者的风险分层以及长期监测治疗反应可能也是一种有用的方式。本文重点介绍CMR在肥厚型和浸润性心肌病评估以及（如相关）风险分层中的作用。
