[Recent advance in diagnostic imaging: NMR].

Application of NMR, whether in imaging or in spectroscopy, is evolving rapidly and its clinical feasibility is to be fully assessed. It is not clear if speculation today will hold true tomorrow, but here present status of NMR in medicine, especially in its roles in research of the central nervous system are discussed as follow; NMR imaging in brain tumors, cerebrovascular diseases, degenerative diseases, trauma, spinal cord diseases, Imaging by surface coil, Contrast material in NMR imaging, Blood flow measurement by NMR, Chemical shift imaging, Studies of metabolism by 31P NMR spectroscopy, Recent advances and possible future role of NMR in medicine.
