Abstract

Aim

The magnetic resonance imaging (MRI)–based vertebral bone quality (VBQ) score can be used as a screening tool for identifying patients who may have osteoporosis; however, a significant influence of the magnetic fields of 1.5 T and 3.0 T on the score has been reported. The purpose of this study was to introduce a novel calibration to overcome the problem.

Materials and Methods

We standardised fat infiltration measurement by calibrating the VBQ score to subcutaneous fat, terming it the calibrated-VBQ score. We retrospectively collected patients who underwent both the 1.5-T and 3.0-T MRI examinations. The self-paired VBQ score, a modified-VBQ score, and the calibrated-VBQ score were compared between different magnetic fields. Correlation analysis and receiver operating characteristic (ROC) curve analysis were performed.

Results

The study included 83 patients (mean age: 67.7 ± 8.3 years). The analysis of self-paired patients revealed that the 1.5-T and 3.0-T magnetic fields had no influence on the calibrated-VBQ score, whereas a significant influence on the VBQ scores and the modified-VBQ score was found. By correlation analysis and ROC curve analysis, a better diagnostic effect of the calibrated-VBQ score for osteoporosis could be found than with the VBQ score and the modified-VBQ score.

Conclusion

The calibrated-VBQ score could overcome the inconsistency between the magnetic fields of 1.5 T and 3.0 T, and it could be considered as a better screening tool for osteoporosis compared with the traditional VBQ scores.

一种评估腰椎骨质疏松症的椎体骨质量评分的新校准方法。

目的：基于磁共振成像（MRI）的椎体骨质量（VBQ）评分可作为鉴别骨质疏松症患者的筛查工具；然而，有报道称，1.5 T和3.0 T的磁场对分数有显著影响。本研究的目的是引入一种新的校准方法来克服这个问题。材料与方法：我们通过标定皮下脂肪的VBQ评分，将脂肪浸润测量标准化，称之为标定VBQ评分。我们回顾性收集了同时接受1.5 t和3.0 t MRI检查的患者。比较不同磁场下的自配对VBQ、修正VBQ和校准VBQ得分。进行相关分析和受试者工作特征（ROC）曲线分析。结果：纳入83例患者，平均年龄67.7±8.3岁。对自配对患者的分析显示，1.5 t和3.0 t磁场对校正后的VBQ评分无显著影响，而对校正后的VBQ评分有显著影响。通过相关分析和ROC曲线分析发现，校正后的VBQ评分对骨质疏松症的诊断效果好于校正后的VBQ评分和修正后的VBQ评分。结论：校正后的VBQ评分能够克服1.5 T与3.0 T磁场不一致的问题，与传统的VBQ评分相比，可作为骨质疏松症的一种更好的筛查工具。
