概括
这项研究发现,虽然一些面测量显示出中等的可靠性,但多探测器计算机断层扫描 (MDCT) 和圆束计算机断层扫描 (CBCT) 软件分析对呼吸道评估有局限性.
科学领域:
- 牙科 牙科是指牙科的专业.
- 放射学 放射学是一门学科.
- 矯正牙科 矯正牙科是一種矯正牙科.
背景情况:
- 精确的面和呼吸道测量在正牙科和面外科手术中至关重要.
- 多探测器计算机断层扫描 (MDCT) 和圆束计算机断层扫描 (CBCT) 是用于这些评估的先进成像模式.
- 软件分析在量化这些测量中发挥着关键作用.
研究的目的:
- 为了比较MDCT和CBCT的内部和内部检查员可靠性,使用Amira和海豚软件进行面和气道测量.
- 评估多个检查人员执行的测量结果的一致性.
主要方法:
- 六名牙科住院医生分析了5名成年人和一个干骨的匿名CBCT和MDCT扫描文件.
- 检查人员使用阿米拉和海豚软件进行了26项特定的面和呼吸道测量.
- 内部和内部检查员的可靠性是使用类内相关系数 (ICC) 进行评估的.
主要成果:
- 对某些骨测量 (例如,鼻子宽度,前额部 suture) 观察到中等到实质性的协议.
- 阿米拉显示出相对可靠的气道评估,而海豚软件显示出体积气道测量的标准偏差明显更大.
- 与CBCT相比,MDCT扫描导致气道体积和面积测量较小,除了口内气道体积外.
结论:
- 使用这些CT模式和软件进行骨测量可能不可靠.
- 海豚软件用于呼吸道分析的可靠性较低,这引发了人们对其临床实用性的担忧.
- 使用CT对面结构变化和气道尺寸之间的定量相关性需要谨慎解释,因为测量不一致.

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...
