We developed a methodology to measure the reversible and irreversible transverse relaxation rates R2' and R2, respectively, of multiple spectral peaks from spectroscopic sampling of both sides of a single spin echo. The methodology was applied to resonances in muscle and brain and the irreversible relaxation rates R2 were compared with conventional measurements made from right side only spectra acquired at multiple PRESS echo times.
