In-vivo imaging of deep cerebellar structures and deep
nuclei is difficult even by MRI due to their small size
and limited contrast. In this work we aimed at a
visualization and characterization of the fine
corrugated band that represents the dentate nucleus (DN)
by means of high-resolution Quantitative Susceptibility
Mapping (QSM) at 7T. QSM depicted the DN band with
significantly better contrast than T2*-weighted images
or T2* maps. Quantitative susceptibility differences of
the right and left DN band with respect to frontal white
matter could be measured. QSM-based estimates of right
and left DN band volumes are also reported.
