概括
这项研究引入了一种基于CT的方法,以使下带 (CoP) 和冠状腺 (CrP) 过程长度正常化. 该协议有效地区分正常变异和特定的下病理,如增生和再吸收.
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.
- 人体解剖学 解剖学 解剖学
背景情况:
- 部过程形态表现出显著的个体间变异性.
- 在标准成像中,区分下过程中的生理变异和病理变化可能是具有挑战性的.
- 下巴解剖学的定量评估有助于诊断和治疗规划.
研究的目的:
- 开发和验证一个基于计算机断层扫描 (CT) 的正常化协议,用于下带 (CoP) 和冠状腺 (CrP) 过程.
- 评估正常化比率是否可以从正常变异中区分特定的下病理.
- 为了确定标准化CoP和CrP长度的参考值.
主要方法:
- 对251名健康个体 (502名半) 的CT扫描进行了回顾性分析,以确定参考值.
- 作为参考地标的后高度 (PMH) 的定义.
- 将CoP和CrP长度标准化为PMH的测量 (CoP/PMH,CrP/PMH比率).
- 在冠状腺增生症,状腺增生症和状腺再吸收的患者组中评估正常化比率.
- 使用线性混合效应模型进行统计分析,以检查病理与正常化比率之间的关联.
主要成果:
- 在对照组中,正常化的CoP/PMH和CrP/PMH比率显示出狭窄的预测间隔和定义的参考值.
- 冠状腺增生显示出显著增加的CRP/PMH比率.
- 状细胞增生与增加的CoP/PMH比率有关.
- 淋巴管再吸收与降低COP/PMH比率有关.
- 在正常化比率中观察到明显的,病理特异性的模式.
结论:

Computed Tomography

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...
