概括
圆束计算机断层扫描 (CBCT) 可以识别鼻非对称性,这是癌症的潜在指标. 牙医应该了解这些发现,以避免误诊和不必要的转诊.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 牙科 牙科是指牙科的专业.
背景情况:
- 鼻癌 (NPC) 在亚洲和北非人口中很普遍.
- 放射性鉴定NPC通常涉及检测在Fossa罗森米勒 (FR) 在鼻内不对称.
- 圆束计算断层扫描 (CBCT) 能够可视化鼻及其结构.
研究的目的:
- 评估CBCT在可视化鼻喉和识别不对称性的有用性.
- 在CBCT上确定不同类型的Rosenmüller (FR) 的Fossa的流行率.
- 告知牙科专业人员如何在CBCT上解释鼻发现.
主要方法:
- 分析了83个鼻喉的CBCT扫描.
- 扫描根据罗森穆勒 (FR) 洞穴形态 (A,B,C类型) 进行分类.
- 鼻和鼻的形状在卧式医学成像和垂直牙科CBCT之间进行了比较.
主要成果:
- 罗森穆勒的Fossa (FR) 在男性和女性中观察到A型,B型和C型的频率不同.
- C型 (完全和开放的FR) 在女性中更为普遍.
- 在CBCT上鼻的形状是形,不同于其他成像方式中的立方形状.
结论:
- CBCT有效地可视化鼻,有助于检测不对称性,特别是罗森穆勒洞穴 (FR).
- 牙医可以识别这些不对称性,但应谨慎预防假阳性转诊.
- 临床相关性,包括为淋巴腺病的部检查,对于准确的诊断至关重要.

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...

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
