Regional changes in the 31P metabolite concentration of the whole liver can be acquired using a multi-channel phased-array 31P coil. However, changes in coil placement, separation between anterior and posterior coil, and spectroscopic imaging setup can significantly affect the reproducibility of the data. Methods to maximize data reproducibility including reproducible coil placement and spectroscopic planning, correction of coil sensitivities, and evaluation of the data variability from one scan to another for a whole liver 31P 2D MRSI experiment is presented for a dual tuned 8-channel 31P/1H coil.
