- W4385655590 abstract "Abstract Objective: We plan to conduct a single-center retrospective study to measure the vertebral bone quality (VBQ) of people of all ages and make statistics on the changes in VBQ with age. Then the differences in VBQ under various MRI parameters were compared. Finally, 30 healthy adults were recruited to validate the differentiation VBQ in various parameters. Methods: We first screened patients without underlying disease and no history of fractures who underwent lumbar MRI in our center in the past four years. For ten years as a group, each group randomly selected 1.5T, 3.0T 200 (100 males/100 females) patients. Then, we counted the patients hospitalized with OVCF in our hospital in the past four years. The 30 healthy adults received 4 times of MRI scans in different parameters to determine the differentiation of VBQ. Results: A total of 2400 patients without OVCF and 405 patients with OVCF were collected. VBQ value of 1.5T was significantly higher than that of 3.0T (2.769±0.494 > 2.199±0.432, P<0.0001). VBQ of 43.31khz in 1.5T was significantly lower than 35.36khz (2.447±0.350 < 2.632±0.280, P<0.05). The differentiation of VBQ in 1.5T and 3.0T was validated by the healthy adults’ results. Conclusions: VBQ remains an effective tool for differentiating patients with OVCF and can be used as a primary screening tool for osteoporosis. However, VBQ is significantly affected by magnetic field intensity and bandwidth and cannot achieve its universality at the proposed beginning." @default.
