| 1 | Correlation of semi-quantitative findings of endolymphatic hydrops in MRI with the audiometric findings in patients with Meniere's disease显示文摘Purpose:To investigate the correlation between vestibular hydrops(VH),cochlearhydrops(CH),vestibular aqueduct non-visibility(VANV),and visually increased perilymphatic enhancement(VIPE)with the findings of pure-tone audiometry(PTA)in Meniere’s disease(MD)patients.Methods:In this cross-sectional study,53 ears belonging to 48 patients were divided into two groups and evaluated.In group“MD patients,”there were 24 ears of 19 patients diagnosed with the definite MD(14 patients with unilateral and 5 patients withbilateral involvements).The“control group”consisted of 29 non-symptomatic ears belonging to patients diagnosed with unilateral sudden sensory-neural hearing loss or unilateral schwannoma.All the patients underwent 2 sessions of temporal bone MRI using the same 3T system:an unenhanced axial T1,T2,and 3D-FLAIR MRI,an intravenous gadoliniumenhanced axial T1 fat-sat,and 4 h after the injection,an axial 3D-T2 cube and 3D-FLAIR session.VH,CH,VANV,and VIPE were assessed.Subsequently,the correlation between EH indices and PTA findings(in three frequency domains of low,middle,and high)were evaluated,and the predictive value of MRI was calculated.Results:VH was significantly correlated with the hearing threshold in the low,middle,and highfrequency domains.CH was also correlated with the hearing threshold in the low and middle domains.Contrarily,VIPE was not associated with hearing thresholds,and VANV was only correlated with the hearing threshold in low frequencies.Conclusion:The grade of VH,CH,and VANV were significantly correlated with the hearing thresholds in PTA. | Mohammad Ali Kazemi Ali Ghasemi Jan W.Casselman Mohammad Shafiei Masoud Motasaddi Zarandy Hashem Sharifian Hassan Hashemi Kavous Firouznia Behnaz Moradi Kianosh Kasani Azin Etemadimanesh | 2022 | Journal of Otology2022，17，3： | 0 |
