| Abstract;Nuclear maguetic resonance (NMR) 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 functional magnetic resonance imaging (fMRI) and EPISTAR cerebral blood flow imaging. The second category of techniques deals with apparent difftision tensor in probing the cellular aspects of brain function and is represented by magnetic resonance axonography (MRX). The third category of techniques is the oldest and as yet the most underutilized. These techniques which include MR spectroscopy (MRS) and spectroscopic imaging (SI), are based on classical NMR spectroscopy and are capable of providing biochemical information in vivo. In these critically important but highly demanding techniques, high-field systems possess significant advantages over conventional systems. (author abst.) |
