心血管MRI用于二尖瓣病变进展

Application progresses of cardiovascular MRI in mitral valve diseases

随着心血管MRI(CMRI)技术的进步,多模态CMRI已广泛用于评估二尖瓣病变,可显示瓣膜解剖学结构、评估瓣膜病变严重程度、量化心腔容积及心肌纤维化,在二尖瓣狭窄、二尖瓣关闭不全及其危险分层方面取得较多进展。本文围绕CMRI评估二尖瓣病变进展进行综述。

In recent years,cardiovascular MRI(CMRI)technology has made significant advances,and multimodal CMRI imaging has been useful to display anatomical structure of the valves,to assess the severity of valvular disease,and to quantify the volume of cardiac chambers and myocardial fibrosis,as well as led to progress in judging mitral stenosis,mitral valve closure insufficiency,and risk stratification.Hence they have been widely used in the assessment of mitral valve lesions.The research progresses of CMRI for assessing mitral valve lesions were reviewed in this article.
