We tested for correlations between the planimetric and volumetric measurements, to identify their advantages and disadvantages.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> HYDROPS2-Mi2 EH images were acquired for 32 ears (16 patients): 16 ipsilateral ears of MD patients (MD-ears) and 16 contralateral ears. Three-T MR unit with a 32-channel phased-array coil\/the contrast agent to fill the perilymphatic space and the HYDROPS2-Mi2 sequence. We calculated the EH% [(endolymph)\/(endolymph+perilymph)] ratio and analyzed the entire inner ear in terms of the volumetric EH% value, but only single cochlear and vestibular slices were subjected to planimetric EH% evaluation. The EH% values were compared between MD ears and non-MD ears, to evaluate the diagnostic accuracy of the two methods.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The volumetric EH% was significantly higher for MD vestibules (50.76 \u00b1 13.78%) than non-MD vestibules (39.50 \u00b1 8.99%). The planimetric EH% was also significantly higher for MD vestibules (61.98 \u00b1 20.65%) than non-MD vestibules (37.22 \u00b1 12.95%). The vestibular and cochlear volumetric EH% values correlated significantly with the planimetric EH% values of the MD ear.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Volumetric and planimetric EH measurements facilitate diagnosis of MD ears compared to non-MD ears. Both methods seem to be reliable and consistent; the measurements were significantly correlated in this study. However, the planimetric EH% overestimates the extent of vestibular hydrops by 26.26%. Also, planimetric data may not correlate with volumetric data for non-MD cochleae with normal EH% values.<\/jats:p>","DOI":"10.3389\/fneur.2021.710422","type":"journal-article","created":{"date-parts":[[2021,9,13]],"date-time":"2021-09-13T05:42:48Z","timestamp":1631511768000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Three-Dimensional Volumetric Measurement of Endolymphatic Hydrops in Meniere's Disease"],"prefix":"10.3389","volume":"12","author":[{"given":"Tae-Soo","family":"Noh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moo Kyun","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun Ho","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung Ha","family":"Oh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji-Hoon","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"In Chan","family":"Song","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myung-Whan","family":"Suh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2021,9,13]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"138","DOI":"10.1055\/s-0039-3402065","article-title":"Current understanding and clinical management of meniere's disease: a systematic review","volume":"40","author":"Perez-Carpena","year":"2020","journal-title":"Semin Neurol."},{"key":"B2","doi-asserted-by":"publisher","first-page":"1","DOI":"10.3233\/VES-150549","article-title":"Diagnostic criteria for Meniere's disease","volume":"25","author":"Lopez-Escamez","year":"2015","journal-title":"J Vestib Res."},{"key":"B3","doi-asserted-by":"publisher","first-page":"873","DOI":"10.1177\/000348948909801108","article-title":"Meniere's syndrome and endolymphatic hydrops.
