Osteoporosis is a burgeoning public health problem for over 44 million people in the United States. The magnetic resonance imaging-based vertebral bone quality (VBQ) score and cervical VBQ (C-VBQ) score are two novel approaches that use data routinely gathered during preoperative evaluation to assess bone quality. The goal of this study was to investigate the relationship between the VBQ and C-VBQ scores.
We performed a retrospective review of chart data for patients who underwent spine surgery for degenerative conditions between 2015 and 2022. Patients eligible for study inclusion had preoperative T1-weighted magnetic resonance imaging of the lumbar and cervical spine available for review. Demographics of each patient were collected. The VBQ score was determined by dividing the median signal intensity (SI) of the L1-L4 vertebral bodies by the SI of the cerebrospinal fluid at L3. The C-VBQ score was calculated by dividing the median SI of the C3-C6 vertebral bodies by the SI of the C2 cerebrospinal fluid space. Pearson's correlation test was utilized to evaluate the association between the scores.
We identified 171 patients, with a mean age of 57.44 ± 11.79 years. The interrater reliability of the VBQ and C-VBQ measurements was excellent (intraclass correlation-coefficients were 0.89 and 0.84, respectively). A statistically significant, positive correlation was found between the VBQ score and the C-VBQ score (r = 0.757,P < 0.001).
This is the first study, to our knowledge, to assess the degree to which the newly developed C-VBQ score correlates with the VBQ score. We found a strong positive correlation between the scores.
骨质疏松是美国超过4400万人面临的一个新兴公共卫生问题。基于磁共振成像的椎体骨质量（VBQ）评分和颈椎VBQ（C-VBQ）评分是两种新方法，它们利用术前评估期间常规收集的数据来评估骨质量。本研究的目的是调查VBQ评分与C-VBQ评分之间的关系。
我们对2015年至2022年间因退行性疾病接受脊柱手术的患者的病历数据进行了回顾性研究。符合研究纳入标准的患者有术前腰椎和颈椎的T1加权磁共振成像可供审查。收集了每位患者的人口统计学数据。VBQ评分通过将L1-L4椎体的中位信号强度（SI）除以L3处脑脊液的SI来确定。C-VBQ评分通过将C3-C6椎体的中位SI除以C2脑脊液间隙的SI来计算。采用Pearson相关检验来评估评分之间的关联。
我们确定了171例患者，平均年龄为57.44±11.79岁。VBQ和C-VBQ测量的评分者间信度极佳（组内相关系数分别为0.89和0.84）。VBQ评分与C-VBQ评分之间存在统计学上显著的正相关（r = 0.757，P < 0.001）。
据我们所知，这是第一项评估新开发 的C-VBQ评分与VBQ评分相关程度的研究。我们发现评分之间存在强正相关。
