Quantitative study of vestibular endolymphatic hydrops in Meniere’s disease based on Three-Dimensional real Inversion Recovery (3D-real IR) sequence

3D-real IR MRI enables quantitative EH assessment, with ELR thresholds providing objective grading criteria. EH severity reflects pathophysiological progression through its associations with auditory/vestibular dysfunction and disease stage, while demonstrating stability of total vestibular volume. This methodology addresses limitations of subjective grading systems, offering standardized metrics for clinical research and therapeutic monitoring.
