The current data show a comparison between different MRI
contrasts at 7T that were used previously to map
cortical myelin content. Previous papers showed that
differences in intensity levels between the cortical
areas may reflect the overall cortical myelin content.
However, it is not clear whether different contrasts
(i.e. weighted vs. quantitative) show comparable
myelination patterns. Minor differences were found
between the tested contrasts (T1w, T2*w, R1, qT2*,
T1w/T2w, R1/qT2*). These variances could be partially
induced by qT2* effects. Nevertheless, other factors
like curvature and cortical thickness should be taken
into consideration for future analyses.
