Abstract: The fundamental principle of MRI is introduced briefly, and Compared with the traditional NMR spectroscopy. The recent research works of MRI are listed, and a diagram of research works system is made by the author. Particular emphases are placed on problems of fast imaging, high spacial resolution and contrast enhancement, etc. The problems of developing the chemical shift imaging and spectroscopic imaging are reviewed in detail. A new field of "Spacial Localized Spectroscopy" is discussed with the author's viewpoint in detail, also.
