T2 quantification has been used for long time in
clinical routine diagnosis, which relies objectively on
an absolute quantitative T2-map rather than subjectively
on gray-scaled images. Therefore, the reliability of
quantified values should be ensured for clinical
diagnosis. Currently the widely used multiple contrast
spin echo acquisition mainly suffers from non-ideal RF
pulse profiles, resulting in protocol dependent
quantifications. Following our previous work, this study
presents a true CPMG prepared T2-mapping method, which
minimizes the impacts of the RF pulse profile, yielding
more accurate T2-maps.
