摘要
Magnetic resonance (MR) is a remarkably versatile technology applicable to various aspects of medical science. Currently, there are three categories of MR techniques available for probing human brain function in detail. The first category comprises the most widely utilized techniques which make use of the metabolic effects of brain activation, represented by BOLD (blood oxygen level dependent) functional magnetic resonance imaging (fMRI). The second category of techniques deals with apparent diffusion tensor in probing the axonal connectivity and is represented by three dimensional anisotropy contrast (3DAC) axonography. The third category of techniques is a biological application of classical nuclear magnetic resonance (NMR) spectroscopy capable of providing biochemical information in vivo and is represented by spectroscopic imaging (SI). As techniques directly applicable to clinical medicine, BOLD, fMRI, and 3DAC axonography possess the highest potential.
