概括
脊椎骨质量 (VBQ) 评分与骨矿物质密度 (BMD) 的相关性较弱至中等,骨质疏松症和骨折的诊断准确性有限. 最好将VBQ作为DEXA或CT扫描的辅助工具使用.
科学领域:
- 放射学 放射学是一门学科.
- 整形外科 整形外科 整形外科
- 骨健康 骨健康 骨健康
背景情况:
- 骨质疏松症诊断和骨折预测对于患者管理至关重要.
- 双能X射线吸收计 (DEXA) 是骨矿物质密度 (BMD) 评估的黄金标准.
- 通过MRI进行脊椎骨质量 (VBQ) 评分提供了一个潜在的替代或补充方法.
研究的目的:
- 为了比较单段和多段VBQ分数.
- 评估VBQ在评估BMD,诊断骨质疏松症和预测脆弱性骨折方面的准确性.
- 为了确定最准确和最实用的VBQ测量方法.
主要方法:
- 对210名接受腰椎MRI和DEXA的患者进行了回顾性分析.
- 单段 (L1-S1) 和多段 (L1-L4,L1-L5,L1-S1) VBQ分数的计算.
- 与DEXA衍生的BMD和ROC曲线分析进行相关性分析,以提高诊断准确度.
主要成果:
- 所有的VBQ得分都显示出与BMD有显著的,尽管较弱至中度的相关性.
- 在单个细分市场中,VBQL2表现出最强的相关性和最佳AUC.
- 在多段评分中,VBQL1~L4显示出最强的相关性和最佳整体诊断性能,AUC低于0.70.
结论:
- 作为一个独立的工具,VBQ分数的诊断实用性有限.
- VBQL2和VBQL1~L4在单个和多段方法中分别略有优势.
- 应该考虑VBQ作为DEXA或CT的辅助,特别是对于腰部MRI但没有DEXA/CT接入的患者.

Non-destructive Tests for Concrete Strength
The rebound hammer test, also known as the Schmidt hammer test, is a non-destructive technique for evaluating the hardness of concrete and, indirectly, the strength of concrete. It operates on the principle that the rebound of a spring-driven mass from a concrete surface correlates to the surface's hardness. The device comprises a mass within a tubular housing, a spring mechanism, and a plunger that strikes the concrete. Upon release, the energy imparted to the mass by the spring causes it to...
Measurement of Air Content in Concrete
Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.
