About this trial
Imaging endolymphatic hydrops with 7T Sodium Imaging and 1.5 T gadolinium enhanced imaging: a comparison of diagnostic outcomes with 3T MRI
Duration of study 24 months
Study design Prospective cohort study
Number of patients 16 patients
1. To evaluate whether imaging both 1.5T and 3T have an equivalent performance in terms of diagnosing MD ears with delayed post gadolinium enhanced MRI (applying quantitative and semi-quantitative analysis) 2. To compare the diagnostic performance of Sodium Imaging at 7T (applying semi-quantitative analysis) with that of delayed post gadolinium enhanced 3T MRI in distinguishing symptomatic from asymptomatic Meniere's Disease (MD) ears.

Trial outcomes
Primary outcomes
The qualitative asymmetry of perilymphatic enhancement and the quantitative signal intensity ratio of the cochlea with delayed post gadolinium 3T and 1.5T.
The semi-quantitative scoring of endolymphatic hydrops and the quantitative volume of endolymphatic and perilymphatic structures with delayed post gadolinium 3T and 1.5T.
Semi-quantitative analysis (including ratios to internal references and the contralateral ear) of the vestibule on Sodium Imaging at 7T
