Diagnostic Model Based on Delayed Post-Gadolinium Enhancement MRI Accurate for Meniere Disease
By Elana Gotkine HealthDay Reporter
TUESDAY, July 15, 2025 -- A diagnostic model based on delayed post-gadolinium enhancement magnetic resonance imaging (DEMRI) improves the accuracy of Meniere disease (MD) diagnosis, according to a study published online July 8 in Diagnostic and Interventional Radiology.
Xinyi Chen, from The Second Affiliated Hospital in Hangzhou, China, and colleagues examined the diagnostic performance of DEMRI for MD in a retrospective multicenter study conducted in patients presenting with Menieriform symptoms. A total of 162 ears were included: 95 with MD and 67 controls. Each ear was randomly assigned to the training set or validation set (98 and 64, respectively). Diagnostic models for MD were developed using logistic regression in the training cohort. Diagnostic performance of different models was examined using the area under the curve (AUC), and AUC estimates were compared between models using the Delong test.
The researchers found that in both the training and validation cohorts, the proposed DEMRI diagnostic model demonstrated strong diagnostic performance (AUC, 0.907 and 0.887, respectively), outperforming the clinical diagnostic model in the validation cohort (P = 0.01231). Although the difference was not statistically significant, the AUC of the DEMRI model was also higher than that of the combined DEMRI-clinical model (AUC, 0.796; P = 0.054). The sensitivity and specificity of the DEMRI model were 78.9 and 88.5 percent, respectively, in the training set.
"We recommend DEMRI when MD is suspected due to its substantial diagnostic potential," the authors write. "Further studies are needed to explore the broader applicability of our model and support its clinical implementation."
