Cardiovascular magnetic resonance (CMR) has increasingly become a powerful imaging technique over the past few decades due to increasing knowledge about clinical applications, operator experience and technological advances, including the introduction of high field strength magnets, leading to improved signal-to-noise ratio. Its success is attributed to the free choice of imaging planes, the wide variety of imaging techniques, and the lack of harmful radiation. Developments in CMR have led to the accurate evaluation of cardiac structure, function and tissues characterisation, so this non-invasive technique has become a powerful tool for a broad range of cardiac pathologies. This review will provide an introduction of magnetic resonance imaging (MRI) physics, an overview of the current techniques and clinical application of CMR in structural heart disease, and illustrated examples of its use in clinical practice.
在过去几十年中，由于对临床应用的认识不断加深、操作人员经验的积累以及技术进步（包括引入高场强磁体，从而提高了信噪比），心血管磁共振成像（CMR）已日益成为一种强大的成像技术。其成功归因于成像平面的自由选择、多种成像技术以及无有害辐射。CMR的发展已能够对心脏结构、功能和组织特征进行准确评估，因此这种非侵入性技术已成为广泛应用于多种心脏疾病的有力工具。本综述将介绍磁共振成像（MRI）物理学，概述CMR在结构性心脏病中的当前技术及临床应用，并举例说明其在临床实践中的应用。
