At this second Discussion Meeting on NMR imaging, we have seen a broad range of imaging and spectroscopic activities from imaging of solids, microscopic imaging, high-speed imaging and spectroscopic imaging. It has been 11 years since the first Discussion Meeting, and the object at this meeting was to review the recent developments and consider the future prospects. We have all been amazed by the developments in solid imaging and the quality and resolution that can now be achieved by combining line narrowing methods with gradient pulsing or with gradient modulation. The future for solid imaging with its wide potential is assured. Progress in free radical imaging using proton-electron double resonance was also briefly reviewed. Detection of natural levels of free radicals in biological tissue is some way off, but the progress with this technique is impressive.
