Phosphorous (31P) spectra of healthy human kidney are invaluable in studies of kidney physiology, disease and in the evaluation of allograft viability pre and post renal transplantation. However, 31P-spectroscopy of the kidney in-situ is challenging due to the relatively large distance between the kidney and the surface coil. The aim of this study was to investigate whether it is possible to acquire 31P spectra of normal kidney in a clinically acceptable measurement time using a 3T MR scanner. We demonstrate that localized phosphorous spectroscopy of normal kidney in-situ is feasible in today’s 3T clinical MR systems.
