· 31P-MRS of normal human kidney in-situ is feasible on 3T clinical MR systems in an acceptable measurement time.
· The amplitudes of b-ATP resonances are decreased due to the narrowing of the effective excitation bandwidth with respect to distance from the surface coil.

coronal and sagittal planes. A small water-containing bottle (circled) was
attached to the centre of the coil as a marker of coil position.
