The relaxation parameters of CSF may have
potential as imaging markers in several diseases. In this work T2
mapping of CSF in the lateral ventricles and in the fourth ventricle was performed
in six volunteers at 7T, with comparison to 3T. The sensitivity for B1
was assessed by comparing the T2s in both regions, with equal B1
at 3T and different B1 at 7T. T2 values were
significantly lower at 7T compared to 3T. No significant difference was found
between the lateral and the fourth ventricular T2s at 7T (and 3T),
indicating negligible B1-sensitivity for the used T2-mapping
sequences.
