To investigate the reliability and validity of MRI for supporting a diagnosis of facial neuropathy in dogs, we examined MR images of the brainstem from 20 dogs with presumed idiopathic facial neuropathy, and 20 control dogs. Two different types of MRI sequence were compared: volumetric interpolated breath\u2010hold examination MRI (VIBE\u2010MRI), and conventional T1\u2010weighted MRI. Three independent observers, blinded to the case details, were presented with VIBE\u2010MR images in a random order, and were required to indicate the presence of hyperintensity of the facial nerve following intravenous contrast administration. The vestibulocochlear nerve was also assessed, and the whole process was repeated for conventional post\u2010contrast T1\u2010weighted images. Following contrast administration, the sensitivity of VIBE\u2010MRI for detecting facial nerve abnormalities ranged from 86 per cent to 96 per cent, and the specificity from 87 per cent to 92 per cent; conventional T1\u2010weighted images yielded a sensitivity of only 39 per cent \u2013 65 per cent, and a specificity of 94 per cent \u2013 96 per cent. MRI was not a sensitive detector of vestibulocochlear nerve abnormalities in 14 dogs with concurrent vestibular dysfunction. This study shows that VIBE\u2010MRI is a robust technique for confirming presumed idiopathic facial neuropathy in dogs, and suggests an inflammatory component to this condition in a high proportion of dogs.<\/jats:p>","DOI":"10.1136\/vr.100877","type":"journal-article","created":{"date-parts":[[2012,8,7]],"date-time":"2012-08-07T23:49:42Z","timestamp":1344383382000},"page":"349-349","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":23,"title":["Sensitivity and specificity of MRI for detecting facial nerve abnormalities in dogs with facial neuropathy"],"prefix":"10.1002","volume":"171","author":[{"given":"P.
