Computed Tomography01:10

Computed Tomography

4.3K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

科学领域:

  • 整形外科和骨生物学
  • 医学成像和诊断 医学成像和诊断

背景情况:

  • 局部的脊椎骨损失 (空隙) 与骨脆弱性有关,但通常使用高分辨率的外周定量计算断层扫描 (HR-pQCT) 来测量,这仅限于外围部位.
  • 目前尚不清楚这些空隙是否发生在轴性骨部位,需要进一步调查.

研究的目的:

  • 验证使用定量计算机断层扫描 (QCT) 来评估部和脊柱的空隙空间.
  • 通过结合QCT和HR-pQCT测量来确定空白空间的系统流行率.

主要方法:

  • 调整了HR-pQCT的QCT方法来评估101名参与者的空虚空间 (体积和比率),并比较不同模式的结果.
  • 在209名参与者的单独队列中,使用HR-pQCT (半径,骨) 和QCT (腰椎,部) 测量了空虚空间.
  • 通过使用皮尔森的相关性,对整个骨部位的空空空间测量之间的关系进行了评估.

主要成果:

  • 对HR-pQCT的QCT验证显示,在膝盖的空隙体积 (r=0.88) 和比率 (r=0.83) 之间存在很强的相关性.
  • 虚空空间比相关性在类似的骨部位 (例如,腰椎水平) 之间是最高的,在不相似的部位 (例如,半径和脊柱) 之间是较弱的.

结论:

  • 定量计算断层扫描 (QCT) 已被验证用于识别骨空隙空间,以前只能用HR-pQCT进行测量.
  • 空虚空间是局部化到特定的骨区域,而不是系统性的.
  • 追踪空隙提供了有关骨脆弱性的见解,并可能指导未来的骨科治疗.
