“…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] .…”

“…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] .…”

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.

“…This is an essential imaging technique as well to confirm the diagnosis of the dehiscence. Recently Browaeys et al proposed MRI as screening tool for dehiscence exclusion (sensitivity of 100 % and specificity of 99.1 %) [16]. Although MRI can give a false positive result for the inner ear dehiscence, in the present cases the MRI findings were correlated well with the clinical data.…”

Reikšminiai žodžiai: vidinės ausies dehiscencija, jungo venos stormens anomalijos, vertigo, pulsuojantis ūžesys. Straipsnyje pristatomi užpakalinio pusratinio kanalo ir prieangio vandentiekio dehiscencijų atvejai dėl jungo venos stormens anomalijų. Taip vadinamos trečiojo lango ligos yra neseniai aprašytos patologinės būklės, sukeltos dalinio kaulinio labirinto ar sraigės kapsulės nebuvimo. Šio straipsnio tikslas – pateikti jungo venos stormens anomalijų sukeltų dehiscencijų simptomus ir jų vystymosi eigą. Taip pat dėl galimų užpakalinių pusratinių kanalų ir prieangio vandentiekio dehiscencijų, sukeltų jungo venos stormens anomalijų, buvo peržiūrėti aukštos rezoliucijos kompiuterinės tomografijos vaizdai pacientų, sergančių lėtiniu vidurinės ausies uždegimu su arba be cholesteatomos. Retrospektyviai buvo ieškoma koreliacijų tarp šių neurovizualinių vaizdų ir otoneurologinių simptomų. Trys pacientai turėjo simptomines dehiscencijas, tačiau kiti keturi su radiologiniais dehiscencijų požymiais nenurodė jokių specifinių nusiskundimų. Aukštas jungo venos stormuo, jungo venos stormens divertikulas – dažni radiniai smilkinkaulių kompiuterinės tomografijos vaizduose. Kai kuriems pacientams jie gali sukelti otoneurologinius simptomus. Straipsnyje vidinės ausies dehiscencijų klinikinės charakteristikos, audiologiniai ir radiologiniai požymiai yra kritiškai aptariami. Pabrėžiama, kad kiekvienos dehiscencijos atveju klinikiniai simptomai ir radiologiniai radiniai turi koreliuoti tarpusavyje.

“…Según Krombach y col 48 la RM tiene una sensibilidad del 96% y una especificidad del 98% y según Browayes y col 49 obtuvieron una sensibilidad y un valor predictivo negativo del 100%, una especificidad del 99,1% y un valor predictivo positivo del 33,3%. Inal y col 50 concluyen que se realice RM para el diagnóstico de una dehiscencia y solo en caso de duda se debe realizar un examen de TC.…”

Can MRI Replace CT in Evaluating Semicircular Canal Dehiscence?

Abstract: BACKGROUND AND PURPOSE:Patients with symptoms of semicircular canal dehiscence often undergo both CT and MR imaging. We assessed whether FIESTA can replace temporal bone CT in evaluating patients for SC dehiscence.
