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.
