In-vivo results of 31P MR Spectroscopic Imaging (MRSI) of a whole axial slice through the liver obtained from a novel eight-channel phased-array dual-tuned 31P/1H coil at 3T are presented in this work. Data was acquired using a slice-selective MRSI sequence, showing that this coil allows MRSI of a whole slice of the abdomen and provides good sensitivity throughout the liver. The signal to noise ratio of the spectra allows for relative phase correction before signal combination from each channel. A nominal resolution of 25x25x30 mm3 over a field-of-view of 400x250x30 mm3 can be achieved within a scantime of ~20 min.
