Proton single-voxel PRESS magnetic resonance
spectroscopy of the human prostate at 3 T was performed
using a surface coil. The aim of the study was
estimation prostate water, choline, creatine, and
citrate relaxation times T1, T2. Spectra were processed
by LCModel and AMARES algorithms. T1 and T2 values were
obtained by mono-exponential fitting of the spectral
intensities versus repetition or echo times. Knowledge
of the relaxation times enables quantification of
prostate metabolite concentrations using water as the
internal concentration reference.
