Noninvasive MR-based metabolic imaging of brain tumor may offer new tools for clinic diagnosis and monitoring of tumor growth or assessment of treatment efficacy. One potential candidate is the dynamic deuterium MRS (DMRS) imaging technique recently developed. To reach its full potential, we integrated advanced data processing with D-MRSI to enhance its sensitivity or spatiotemporal resolution. We demonstrated in this pilot study that quantitative “Warburg Effect” map and kinetic time courses of deuterated metabolites can be achieved with good spatiotemporal scales in rat brain tumor using Deep-SPICE based deuterium MRSI, which could potentially be applied to brain tumor patients.
