概括
这项研究表明,2-deoxy-2-[18F]-D-葡萄糖 (F-18-FDG) 定子发射断层扫描 (PET) /计算机断层扫描 (CT) 可以有效地区分性肩关节炎 (SSA) 和骨关节炎 (OA). 一个负的F-18-FDG PET/CT扫描有助于排除SSA.
科学领域:
- 核医学就是核医学.
- 放射学 放射学是一门学科.
- 整形外科 整形外科 整形外科
背景情况:
- 败血性关节炎 (SA) 是一种罕见但严重的关节威胁性疾病.
- 肩部SA通常是由血源性感染传播引起的.
- F-18-FDG PET/CT显示出识别感染和指导治疗的潜力.
研究的目的:
- 使用F-18-FDG PET/CT.区分感染性肩关节炎 (SSA) 和肩关节骨炎 (OA) 的代谢模式.
- 评估F-18-FDG PET/CT在区分SSA和OA方面的诊断性能.
主要方法:
- 对患有SSA的患者和接受F-18-FDG PET/CT的对照者的回顾性分析.
- 对F-18-FDG吸收的视觉和定量分析 (SUVmax).
- 关节和肝脏吸收率的计算和关节炎严重程度的评估 (凯尔格伦和劳伦斯系统).
主要成果:
- 在SSA中,F-18-FDG的摄入量明显高于OA (P < .001).
- 关节-肝脏比率切断值为1显示了SSA检测92.3%的灵敏度和80.9%的特异性.
- 对SUVmax和视觉分析的观察者间和观察者内可靠性中度至高.
结论:
- F-18-FDG PET/CT有效地将SSA与OA区分开来.
- 肝脏吸收量 (SUVmax) 可以作为一个可靠的切断值.
- 一个负面的F-18-FDG PET/CT扫描可以排除SSA.

01:29Positron Emission Tomography
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 being...
