概括
多层全景放射学 (MPAN) 在评估下第三牙和它们与下通道的接近方面显示了与常规全景放射学 (CPAN) 类似的性能. 这两种方法都低估了与形光束计算机断层扫描 (CBCT) 相比的距离.
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.
- 口腔和牙面部外科手术
背景情况:
- 在手术规划中,下第三的手术前评估至关重要.
- 传统的全景放射 (CPAN) 是标准的成像方式.
- 多层全景放射 (MPAN) 是一种新技术,具有潜在的应用.
研究的目的:
- 为了比较MPAN和CPAN的诊断准确性,用于评估下第三牙.
- 使用这两种技术来评估下第三与下通道的距离.
- 使用形束计算断层扫描 (CBCT) 作为参考标准.
主要方法:
- 从33个干燥的人类下部 (56个第三) 中获取CPAN,MPAN和CBCT扫描.
- 三名检查人员对第三的位置,冲击深度和根顶接近下沟的位置进行评估.
- 根顶和下沟之间的距离测量,CBCT作为参考标准.
主要成果:
- 全景模式和CBCT之间的协议范围从66.1%到100.0%.
- CPAN和MPAN与CBCT的总体一致性相似.
- 与CBCT相比,CPAN和MPAN都显著低估了根顶和下沟之间的距离.
- 对MPAN而言,内部和内部检查员的一致性通常高于CPAN.
结论:
- 在评估下第三和它们与下通道的关系方面,MPAN的表现与CPAN相当.
- 尽管性能相似,但与CBCT相比,这两种全景技术都低估了临界距离.
- MPAN显示出有希望的结果,并建议对其他诊断应用进行进一步的研究.

X-ray Imaging
5.6K
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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
