The basic mantra for in vivo MR spectroscopy is to look beyond the dominant water and lipid signals. Although water is very well characterized by MRI, partially suppressed water can provide unique information in proton MR spectra. In the results presented, residual water-by-design strategy is demonstrated to extend beyond use as a reference. For the protocol described, water derived measurements of temperature and hypoxia, add critical value at no compromise.
