The in vivo applications of magnetic resonance spectroscopic imaging (MRSI) have expanded significantly over the past 10 years and have reached the point where clinical trials are underway for a number of different diseases. One of the limiting factors in the widespread use of this technology has been the lack of widely available tools for obtaining data which are localized to sufficiently small tissue volumes to make an impact upon diagnosis and treatment planning. This is especially difficult within the timeframe of a clinical MR examination, which requires that both anatomic and metabolic data are acquired and processed. Recent advances in the hardware and software associated with clinical scanners have provided the potential for improvements in the spatial and time resolution of imaging and spectral data. The two areas which hold the most promise in terms of MRSI data are the use of phased array coils and the implementation of echo planar k‐space sampling techniques. These could have immediate impact for 1 H MRSI and may prove valuable for future applications of 31 P MRSI. © 1997 John Wiley & Sons, Ltd.
