磁共振血管壁成像是利用磁共振原理抑制血管内流动血液信号，获取血管壁等静态组织图像的一种成像方法。由于可以对血管壁进行直接成像，这种方法可以用于评估动脉粥样硬化斑块的形态、成分，进而确定斑块的风险程度。血管壁成像技术的核心问题在于如何有效抑制流动血液的信号，本文就目前磁共振血管壁成像技术的现状及进展做简要的总结回顾。%MR vessel wall imaging (MRVWI) acquires the information of vessel wall by suppressing the signal of flowing blood in lumen area. MRVWI techniques can visualize vessel wall directly and evaluate plaque vulnerability by measuring morphology and components of plaque. The main target of MRVWI techniques is to suppress the signal of the flowing blood. In this survey, we will briefly review the current status and progress in MRVWI techniques.
