摘　　要：随着磁共振成像技术的发展,成像空间分辨率及信噪比不断提高。磁共振成像的对象也由宏观的解剖结构拓展至组织、细胞及分子等微观领域,形成磁共振显微成像。本文首先介绍磁共振显微成像的概念、特点、相比其它显微成像技术所具备的优势,再进一步介绍其在分子影像学、组织胚胎学及小动物实验中一些前沿的研究工作。磁共振显微成像在生物医学的研究中发挥着越来越重要的作用。With the development of engineering and techniques, the spatial-resolution and signal-noise ratio of magnetic resonance imaging is gradually increasing. Not only the macroscopic anatomical structure, but also the microscopic field （such as tissue, cell and molecule） are as the object of imaging and the magnetic resonance microscopy （MRM） was termed. In this review, MRM＇ s definition, characters and advantages are introduced first, and then some current cutting-edge researches on molecular imaging, histology, embryology and animal experiment are presented. MRM will have greater and greater influence on biomedical researches.
