随着彩色多普勒超声心动图的发展，对瓣膜疾病的评价发生了显著的变化。然而，这项技术有其局限性，特别是在评估瓣膜返流方面。磁共振成像以其提供三维形态数据、动态电影信息和使用血流敏感技术进行功能评估的能力，可以被视为一种补充的非侵入性手段，能够提供规划治疗方案所需的完整信息。在磁共振成像中，定量的、准确的和可重复的定量信息，如容量测量、心功能和血流速度曲线，对于评估瓣膜疾病的严重程度是独一无二的。本文综述了各种不同的磁共振成像技术在评价心脏瓣膜病中的应用，并与经典的成像方法比较，讨论了这些技术在目前临床应用中的优势和局限性。
Evaluation of valve disease has changed significantly with the development of color Doppler echocardiography. Nevertheless, this technique has limitations, particularly in the assessment of valvular regurgitation. MR imaging, with its ability to provide three-dimensional morphologic data, dynamic cine information, and functional evaluation with flow-sensitive techniques, can be envisioned as a complementary noninvasive modality, able to provide the complete information required for planning therapeutic options. With MR imaging, qualitative as well as accurate and reproducible quantitative information such as volume measurements, cardiac function, and flow velocity profiles are unique for the evaluation of the severity of valve disease. This article reviews the different MR imaging techniques used in assessing valvular heart disease and discusses the advantages and limitations of these techniques in current clinical applications in comparison with classical imaging methods.
