We present results of quantitative magnetization
transfer imaging (qMTI) in high resolution for
quantification of (qMT) parameters of otherwise MR-invisible
macromolecules. qMTI was performed on a post-mortem
marmoset brain at 3T and the results are compared to T1
mapping results obtained at 7T. The high resolution of
200 m permits visualization of cortical substructures
in the marmoset brain, as presented for the stria of
Gennari. An analysis of correlation between the
macromolecular pool-size fraction and T1 shows different
linear regressions in white and gray matter. This
suggests i) different myelination contribution in both
contrast parameters, or ii) other contributing factors.
