Selected spectra from a 3D 8 × 8 × 16 array of 13C MRSI data acquired in 14 s at 3 T demonstrate dramatic increases in 13C lactate signals in a transgenic prostate tumor after injection of 13C pyruvate that was prepolarized in HyperSense system (Oxford Instruments). Lactate SNR was measured to be 59.9 in kidney and 115.9 in tumor.
