概括
18F]FDG-PET/CT SUV比>1.5有效地表征上腺损伤,有助于避免不必要的手术. 这种成像技术在异质患者群体中表现出高灵敏度和特异性.
科学领域:
- 核医学是一种核医学.
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 关于使用18F]FDG-PET/CT用于上腺损伤特征的数据有限.
- 以前的研究表明,瘤到肝脏的最大标准化吸收值 (SUVratio) >1.5作为恶性瘤的值.
研究的目的:
- 在多样化的患者群体中确定上腺病变的最佳SUVratio切断值.
- 为了评估SUV的诊断性能>1.5门.
主要方法:
- 在2013-2022年期间,对42个经过18F]FDG-PET/CT的上腺病变进行了回顾性分析.
- 通过组织学或12个月的成像随访证实良性.
- 使用ROC曲线评估的最佳SUV比率和SUV比率>1.5的性能.
主要成果:
- 最佳的SUV比率切割值为1.55 (灵敏度为100%,特异性为73.7%).
- 除了叶染色细胞瘤和转移,截止值为1.49 (灵敏度为100%,特异性为96.3%).
- 一个SUV比率的切割值为1.5,产生了100%的灵敏度,87%的特异性,73%的PPV和100%的NPV.
结论:
- 18F]FDG-PET/CT与SUVratio可以协助上腺损伤的临床决策过程.
- 1.5的SUV比率切割值在异质人群中显示出良好的诊断性能,可能减少不必要的手术.

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...
