There have been striking advances recently in magnetic resonance imaging and positron emission tomography (PET) imaging of the central nervous system, particularly in the area of "functional" imaging. We discuss these advances with emphasis on the similarities and differences between the PET and magnetic resonance imaging methods. In addition, we examine recent progress and controversies in the use of volume-localized nuclear magnetic resonance spectroscopy. Finally, we review the use of three-dimensional acquisition for PET studies, with an evaluation of the relative advantages and disadvantages of this modification of the PET technique.
近年来，中枢神经系统的磁共振成像和正电子发射断层扫描（PET）成像取得了显著进展，尤其是在“功能”成像领域。我们将讨论这些进展，重点关注PET和磁共振成像方法之间的异同。此外，我们还将研究体积定位核磁共振波谱学应用方面的最新进展和争议。最后，我们将回顾PET研究中三维采集的应用情况，并评估PET技术这一改进的相对优缺点。
