A New Approach to Visualize Peripheral Vestibular Disorders Using Pseudo-Color Perceptual Enhancement

Objective: Vestibular disorders are rarely diagnosed through imaging examinations intuitively. We try to explore a new approach to visualize peripheral vestibular disorders using pseudo-color perceptual enhancement. Methods : A total of 53 patients with unilateral abnormal caloric test results and 23 patients with normal results, treated at outpatient clinics between March 2025 and March 2026, were selected for analysis. All patients underwent magnetic resonance imaging examinations. We used the software to process T2 sequences from magnetic resonance images of patients and calculated the values of peripheral vestibular organs. Results : Eighteen patients had an abnormal caloric test result on one side but had pseudo-color perceptual enhancement on the other side, thirty five patients had the abnormal caloric test result and pseudo-color perceptual enhancement on the same side, it was statistically different. However, the comparison of differences between both sides in these two groups and the normal group showed no statistically significant difference. Conclusion : The pseudo-color perceptual enhancement on the peripheral vestibular organ may indicate the vestibular disorders. However further research is still needed for the results through more precise differentiation of vestibular disorders.
