For identifying endolymphatic hydrops in individuals with Meniere's disease, four studies found that electrocochleography (EcoG) demonstrated a sensitivity of 66.7-85.7% and a specificity of 80-100% as compared to magnetic resonance imaging. "It seems that tone burst EcoG reaches higher sensitivity rates than click stimulus evoked EcoG in patients with definite Meniere's disease" (p. 426). Due to the limited number of participants across studies, further research is necessary.
