Novel MRI-based score for assessment of bone density in operative spine patients
The Spine Journal Nov 13, 2019
Ehresman J, Pennington Z, Schilling A, et al. - In this retrospective cohort study of 68 persons ≥ 18 years of age who underwent spine surgery for degenerative conditions between 2013 and 2018, researchers designed a simple MRI-based score to assess the bone quality and estimate the degree to which it associated with conventional dual-energy x-ray absorptiometry (DEXA) scores. On the basis of DEXA, 37 had osteopenia/osteoporosis. A greater Vertebral Bone Quality (VBQ) score was markedly correlated with the presence of osteopenia/osteoporosis with a predictive exactitude of 81%. VBQ scores related modestly with femoral neck T-scores, the least overall T-scores of each individual, and related fairly to total hip T-scores. In conclusion, this is the first study to associate the novel VBQ score achieved from MRIs with DEXA T-score. It was discovered that this score was an important predictor of healthy vs osteopenic/osteoporotic bone with an efficacy of 81% and found that the VBQ score was modestly associated with femoral neck and overall least T-score.
