摘　　要：心血管磁共振(cardiovascular magnetic resonance,CMR)多种成像技术可以观察心脏结构功能、心肌组织特征乃至能量代谢。包括弥散加权成像(diffusion weighted imaging,DWI)、弥散张量成像(diffusion tensor imaging,DTI)及弥散频谱成像(diffusion spectrum magnetic resonance imaging,DSI)在内的弥散成像技术一直是CMR最具挑战性及目前尚未常规成熟开展的检查技术,尤以DTI及DSI为甚。本综述将重点阐述DTI及DSI的基本技术及近年来在心血管领域的应用进展。With multiple imaging techniques and sequences,cardiac magnetic resonance(CMR)is not only accurate in the assessment of cardiac structure and function but also superior in noninvasive myocardial tissue characterization and even evaluation of energy metabolism.Diffusion imaging techniques including diffusion weighted imaging(DWI),diffusion tensor imaging(DTI)and diffusion spectrum magnetic resonance imaging(DSI)have always been the most challenging and not been developed routinely yet,especially DTI and DSI.This review will focus on the imaging techniques of DTI and DSI and the recent progress of applications in the cardiovascular field.
