H-MRSI
sequence with spectral-spatial refocusing pulses was
evaluated for prostate applications at 7T. The
combination of an external Tx array coil and an Rx
endorectal coil allowed the use of these non-adiabatic
pulses, while retaining sensitivity within the prostate.
Well-resolved spectra in the prostate of patients were
obtained, with some variation due to B

inhomogeneities.
