概括
使用CT和MRI的机会性查可以评估脊椎手术患者的骨矿物密度 (BMD). 这些方法可以预测骨质疏松症和术后并发症,为DEXA扫描提供了替代方案.
科学领域:
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
- 骨的新陈代谢 骨的新陈代谢
背景情况:
- 低骨矿物质密度 (BMD) 增加了脊椎压缩骨折和手术植入物失败的风险.
- 双能X射线吸收计 (DEXA) 是测量骨质量的黄金标准,但对于脊柱手术患者,它不是普遍在手术前进行的.
- 常规的脊柱成像,如CT和MRI,可能会提供机会性的BMD评估.
研究的目的:
- 审查验证CT衍生的霍恩斯菲尔德单位 (HU) 和MRI衍生的脊椎骨质量 (VBQ) 的研究,以进行机会性骨质量测量.
- 评估HU和VBQ在预测术后结果中的有用性.
- 为确定骨质疏松症/骨质疏松症和手术不良事件的查值.
主要方法:
- 对CT (HU) 和MRI (VBQ) 的现有文献进行系统审查,以评估BMD.
- 对与DEXA测量BMD相关联的HU和VBQ研究的分析.
- 对将HU和VBQ与术后并发症 (子沉降,螺丝松动等) 相关的研究的评估. ) 的情况.
主要成果:
- 证据支持机会性CT (HU) 和MRI (VBQ) 的有效性,用于估计脊柱BMD.
- HU和VBQ的测量显示出预测骨质疏松症/骨质疏松症的潜力.
- 这些成像指标与术后并发症风险增加有关.
结论:
- 机遇式CT和MRI可以可靠地评估脊柱手术候选人的骨干硬化.
- HU和VBQ为骨健康和手术结果提供了有价值的预测信息.
- 确定的查门可以指导临床决策和患者风险分层.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...
