概括
超声波风险分层系统 (US-RSS) 有助于评估焦点[18F]氧葡萄糖 (FDG) -PET/CT甲状腺意外瘤 (TI) 中的恶性瘤风险. 虽然减少了活检,但一些系统对侵袭性癌症的敏感性较低,这表明可能需要调整活检标准.
科学领域:
- 核医学就是核医学.
- 放射学 放射学是一门学科.
- 内分泌学 在内分泌学.
背景情况:
- 焦点[18F]氧葡萄糖 (FDG) -PET/CT甲状腺意外瘤 (TI) 需要对恶性瘤进行准确的风险评估.
- 已建立的超声波风险分层系统 (US-RSS) 在评估TI时具有不同的诊断性能.
研究的目的:
- 评估由五个US-RSSs分类的结核恶性瘤 (ROM) 的风险.
- 评估US-RSS的诊断性能,使用活检标准来诊断焦点FDG-PET/CTTI中的恶性瘤.
主要方法:
- 对216名患者进行了回顾性队列研究,其中236名患者患有FDG-PET/CT TIs.
- 通过活检标准评估了五个美国RSS的诊断性能.
- 通过US-RSSs和SUVmax-US-RSS结合的标准分析了结的ROM.
主要成果:
- 在所有RSS中,中等风险的TI显示出高于预期的ROM (33.8-48.2%).
- 只有在中国TIRADS (35.0%) 中,低风险的TI具有显著更高的ROM (>20%).
- 美国甲状腺协会系统和韩国TIRADS对整体和侵略性恶性瘤具有最高的敏感性 (97.3%);ACR-TIRADS具有最高的特异性 (50.0%) 和最低的不必要活检率 (30.2%).
结论:
- 中等风险的TI在整个系统中增加了ROM;低风险的TI在C-TIRADS中增加了ROM.
- 美国RSS减少了不必要的活检,但欧洲TIRADS,ACR-TIRADS和C-TIRADS对攻击性恶性瘤的敏感性较低.
- 在欧洲和ACR-TIRADS中,中等风险结节和C-TIRADS中低风险结节可能需要较低的活检切断值.

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...
