Examples of qualitative and semi-quantitative analyses of the endolymph on the affected side. ac Visualization of the endolymph: The endolymphatic spaces of the vestibule and semicircular canals were not visualized on PPI for grade 2 (a), but were visualized on PPI for grade 2 (b, arrows) and the corresponding HYDROPS (c). df Signal change in the endolymph: The endolymph of the lateral semicircular canal showed no signal change on PPI for grade 0 (d same as Fig. 1a, arrow), whereas signal change was observed on PPI for grade 0 (e, arrow) as well as the corresponding HYDROPS (f, arrow). gi Endolymphatic hydrops on PPI for grade 2: Vestibular hydrops was graded as no (g, arrows), mild (h, arrows), and significant (i, arrows)
