[Technical aspect of clinical spectroscopic imaging and its recent development--hardware and software].

Today's technical status as well as future developments of clinical spectroscopic imaging were overviewed in terms of hardware and software aspects. For the hardware development, discussion was focused on superconducting magnet with high static fields, new probe designs and fast acquisition of spectroscopic imaging. Some of the technical limitation was also included. In software, pulse shape design for B1 insensitive excitation, selective signal detection utilizing homo- and hetero-nuclear coherence transfer, and post processing of acquired data were briefly discussed. Especially the processed data is important to extract chemical information for the metabolite which can be utilize in the clinical application. Some of the proposed methods were summarized for this.
