電耳蝸圖與釓增強內耳磁振造影對梅尼爾氏病患者之診斷價值

// Diagnostic Value of Electrocochleography and Gadolinium-Enhanced Inner Ear MRI for Patients With Meniere Disease

765耳回溯比較釓增強內耳MRI與耳膜外EcochG（電生理）｜MRI對確定MD敏感79%、特異99%；EcochG area2在疑似MD辨識AUC更高（P<0.05），兩者相關弱，MRI示結構負荷，EcochG敏感早期功能變化、可互補偵測。

// This retrospective cohort study compared extratympanic electrocochleography (EcochG; amplitude, area1, area2 ratios) and gadolinium-enhanced inner ear MRI in 765 ears from 694 patients with definite or probable Menière disease. MRI showed the highest diagnostic accuracy for definite MD versus non-MD (sensitivity 79%, specificity 99%), while the EcochG area2 ratio performed better than MRI for distinguishing probable MD from non-MD (higher AUC, P<0.05). MRI and EcochG correlated only weakly, suggesting MRI reflects structural disease burden in definite MD whereas area-ratio EcochG is more sensitive to early functional changes; thus EcochG may complement MRI for early detection.
