Abstract
Abstract Aim To evaluate the feasibility of lingual nerve visualization using dental-dedicated magnetic resonance imaging (ddMRI), with emphasis on observer reproducibility in a patient series. Materials and Methods Twenty consecutive healthy volunteers underwent a ddMRI examination of the mandibular third molar region. ddMRI was acquired focusing on anatomic and inflammatory tissue characteristics, based on 2D proton-density-weighted image slabs, with and without fat suppression. Three trained observers independently evaluated all ddMRI datasets for image quality (very poor/poor/acceptable/good/optimal) and the anatomical conspicuity of the lingual nerve (visible/not visible). Statistical analysis included the frequency of possible lingual nerve visualization and the inter-observer agreement for that diagnostic task (kappa statistics). Results Overall image quality ranged from acceptable to optimal (average good). The axial plane provided the most consistent visualization of the lingual nerve, which was identifiable in most cases (ranging from 85 to 95% of the cases among observers), although substantial inter-observer reproducibility was observed (kappa values ranging from 0.46 to 0.77, average 0.62). Conclusion ddMRI enables lingual nerve visualization, predominantly in the axial plane. The wide range of inter-observer reproducibility and the lack of clinical validation must be further addressed in larger clinical trials.
