The Diagnostic Value of 1.5T MRI Gadolinium in the Inner Ear for Suspected Meniere Disease
Objective 1.5 TMRI performed MRI scanning of 3D-FLAIR sequence of the inner ear via eustachian tube to investigate the diagnostic value of suspected Meniere's disease.Methods 38 patients with suspicious Meniere disease in our hospital from March 2019 to October 2023 were selected as the study objects for inner ear MRI examination 24 hours after injection of diamide through the eustachian tube,and the analysis of vestibular and cochlear labyrinth water.Results Among the 38 patients with suspected Menier,31 had clinically confirmed disease,4 sudden deafness with vertigo,2 vestibular migraine and 1 Benign paroxysmal positional vertigo.Among the 31 confirmed patients,27 had 32 ears in 27 confirmed patients,including 5 with both ears,22 with single ears,12 with mild ears and 20 with severe ears.One of the non-Menniere patients had mild water and 6 patients without water.The sensitivity of 1.5T MRI was 87.1％and 85.7％,and the area under the ROC curve was 0.864,which had high value for clinical diagnosis.Conclusion The inner ear can clearly show the condition of the labyrinth,and the diagnosis of Meniere's disease is feasible.
