Magnetic resonance spectroscopy (MRS) is a non-invasive method that can provide information of metabolism in-vivo. Recently some clinical trials of MRS using whole body scannar had been performed, but its clinical usefulness remains to be answered. In this article, we presented our clinical experiences of MRS using 1.5T superconducting magnet imager (Magnetom H15, Siemens) and discussed its problems to be resolved for future development.
