In European Congress of Radiology, Austria Center Vienna, 7th to 11th March, 2013. Poster.http://hdl.handle.net/10400.21/2471Pre-operative diffusion tensor (DT) tractography is currently employed in our institutions. We use it to predict the course of the facial nerve (FN) in the vicinity of vestibular schwannomas (VS) of the cerebellopontine angle (CPA). In this study we were interested to assess the inter-observer reproducibility of this method. Two Neuroradiologists (PMGP and TT) determined independently the location of the FN by tractography and compared the results with in-vivo findings of microsurgery of VS.engRadiologyNeuroradiology brainOncologyComputer applicationsMR diffusion/perfusionMR Functional imagingMagnetic resonanceDiagnostic procedureImaging sequencesObserver performanceNeoplasiaMultidisciplinary cancer careImage verificationPre-operative tractography of the facial nerve in vestibular schwannomas: inter-observer agreement with surgical findingsconference object
