Correlation among alveolar bone assessments provided by CBCT, micro-CT, and 14 T MRI

This study aimed to evaluate bone mineral adipose tissue (BMAT) volume in 21 alveolar bone specimens, as determined by 14 T MRI, and correlate them to the radiodensity values obtained pre-operatively of regions of interest (ROIs) by cone-beam computed tomography (CBCT), and to the bone-volume-to-tissue-volume ratio values obtained by micro-CT, the gold-standard for morphometric data collection. Based on the CBCT surgical planning, a CAD/CAM stereolithographic surgical guide was fabricated to retrieve a bone biopsy from the same ROIs scanned pre-operatively and orientate the subsequent implant placement. The findings suggest that 14 T MRI can evaluate BMAT as an indirect marker for bone volume and that CBCT is not a reliable technique to provide accurate bone density values.
