Diagnostic yield of MRI for audiovestibular dysfunction using contemporary referral criteria: correlation with presenting symptoms and impact on clinical management

Abstract

Aim: To investigate the diagnostic yield of T2-weighted magnetic resonance imaging (MRI) screening for vestibular schwannoma and other relevant conditions in the setting of audiovestibular symptoms, given the more liberal contemporary referral criteria. To determine whether presenting clinical symptoms correlate with imaging outcome in order to guide future protocols for MRI referral. Materials and methods: Eight hundred and eighty-one consecutive MRI examinations performed in patients with audiovestibular dysfunction were reviewed. Clinical indications and findings were recorded. Case notes were reviewed in patients with positive imaging findings. Two-way, cross-tabulation, Chi-square analysis was performed to assess the relationship between presenting symptoms and imaging outcome. Results: Twelve of the 881 (1.4%) were positive for vestibular schwannoma. A further four of 881 (0.4%) revealed other relevant conditions. Incidental conditions, felt to be irrelevant to the presenting symptoms, were noted in 12 of the 881 (1.4%). In all 12 cases that were positive for vestibular schwannoma, either tinnitus or hearing loss was present. Conclusion: The yield for T2-weighted MRI to diagnose vestibular schwannoma and other relevant retrocochlear conditions was lower than for previous studies, which is likely to reflect trends in referral criteria. No single audiovestibular symptom or combination of symptoms is a statistically significant  More>>
