Summary
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.
