“…The positive predictive value for the use of MRI was 93.4% and the negative predictive value 83.7% in our study group. This positive predictive value was close to that found in similar studies in the literature [8,10] ; however, the negative predictive value of MRI was lower (33.3%) in a study published by Browaeys et al [10].…”

“…To the best of our knowledge, the first similar study on this subject was reported by Krombach et al [11] in 2004, who found that MRI had a sensitivity level of 96% and a specificity level of 98%. Subsequent studies showed similarly high sensitivity and specificity levels [8,10] .…”

“…In severe cases it may lead to hearing loss. Numerous research studies have been conducted regarding the diagnosis and treatment of this condition in recent years, and while CT is the gold standard for diagnosis since these patients usually complain of neuro-otologic symptoms, MRI is often the preferred primary imaging technique due to better visualization of cranial nerves and the brainstem [2,8,9] . One of the most important goals of these imaging studies is to reduce the cost per patient of diagnosis and prevent delayed diagnosis by requiring multiple imaging modalities.…”

“…MRI is the more commonly used method in patients with neuro-otologic symptoms. Several studies have been conducted to evaluate the efficacy of MRI in diagnosing SSCD to avoid using both imaging modalities, and very high levels of specificity have been found [8,10,11] .…”

“…By reformatting high-resolution CT sections of SSC with 0.5-1 mm intervals (in oblique planes such as those of Pöschl/Stenver), high rates of sensitivity and specificity were obtained. CT has been accepted as the gold standard for the diagnosis of SSCD [5][6][7][8] .…”

OBJECTIVE:This study aimed to evaluate the efficacy of magnetic resonance imaging (MRI) for diagnosing superior semicircular canal dehiscence (SSCD). MATERIALS and METHODS:The radiological records of patients who were admitted to our clinic with complaints of otologic and neuro-otologic symptoms between October 2014 and December 2015 were retrospectively reviewed. Among these patients, those who underwent both computed tomography and MRI and were reported to have SSCD in the temporal bone on at least one side were included in the study group. MRI records of patients with a confirmed diagnosis were then assessed for the presence of SSCD. RESULTS:The left and right semicircular canals of 52 patients were evaluated in this study. The sensitivity and specificity of MRI in the diagnosis of SSCD was 89.06% and 90%, respectively. The positive and negative predictive values were 93.44% and 83.72%, respectively. CONCLUSION:The use of multiplanar reformats and angulation techniques during MRI assessment of patients with neuro-otologic symptoms can improve the diagnostic process for patients with SSCD. This may allow early diagnosis of the disease by using just one imaging method, which would also reduce the costs per patient during the diagnosis period.
