Abstract
Objectives : Determine the utility of low-flip angle “black bone” magnetic resonance imaging (MRI) for cortical mandibular bone assessment compared to computed tomography (CT). Methods : Quantification of cortical mandibular bone width was performed per Hamada et al. at 15 cross-sectional interdentium locations on pre-treatment black bone MRI and CT for 15 oropharyngeal cancer patients, with inter-observer analyses on a subset of 3 patients by 11 observers. CT and MRI measurements were compared using Bland-Altman analysis, Lin’s concordance, and Deming regression; inter-observer variability was assessed with absolute variance and intraclass correlation coefficient (ICC). Results : Bland Altman and Deming regression analyses showed CT and black bone MRI measurements were comparable within ±0.85mm limits of agreement, and systematically smaller for MRI. ICC (0.60[0.52;0.67]) showed moderate equivalence between modalities. The average absolute variance between the observers was similar on CT (1.13±0.06mm) and MRI (1.15±0.06mm). ICC analysis showed that measurement consistency was significantly higher (p
