: The requirement for written informed consent was waived by the Institutional Review Board due to the retrospective nature of the study.

: Institutional Review Board approval was obtained (No.20220403).

: Some study subjects or cohorts have been previously reported in American Society of Neuroradiology and Neuroradiology.1. Fifty study subjects of 273 study subjects in this study have been previously reported in American Society of Neuroradiology. Their cochlear EH grades, vestibular EH grades, and the SIR were reported in that study, however, the aim of that study was to investigated whether a novel high-resolution MR imaging technique, the 3D zoomed imaging technique with parallel transmission real inversion-recovery (3D-ZOOMit real IR), would improve the detection of endolymphatic hydrops compared with conventional 3D TSE inversion-recovery with real reconstruction.2. All study subjects in this study have been previously reported in Neuroradiology. Their cochlear EH grades, vestibular EH grades, and the SIR were reported in that study, however, the aim of that study was to determine whether magnetic resonance imaging (MRI) can improve diagnostic accuracy for definite and probable Ménière’s disease (MD) based on perilymphatic enhancement (PE) and endolymphatic hydrops (EH).
