概括

与FDG PET/CT相比,新的FAPI PET/CT成像显示在复发性分化甲状腺癌中更好地检测小转移. 这种先进的成像可能会导致更早的干预和更好的患者结果.

科学领域:

核医学就是核医学.
在瘤学瘤学.
放射化学放射化学是指辐射化学.

背景情况:

纤维细胞激活蛋白 (FAP) 向的正电子发射断层扫描/计算机断层扫描 (PET/CT) 是一种用于可视化瘤侧膜的新型成像方式.
差异化甲状腺癌 (DTC) 复发通常涉及小的亚临床转移,这些转移很难用传统成像检测.

研究的目的:

评价[18F]AlF-NOTA-FAPI-04 PET/CT 在确定复发性DTC患者的亚临床转移中的诊断性能.
直接比较[18F]AlF-NOTA-FAPI-04 PET/CT与[18F]FDG PET/CT在检测复发性DTC.的有效性.

主要方法:

23名生物化学复发性DTC患者接受了[18F]AlF-NOTA-FAPI-04 PET/CT.
其中16名患者还接受了[18F]FDG PET/CT,以进行直接比较.
损伤确认是基于组织病理学或临床随访,平均为15.5个月.

主要成果:

[18F]AlF-NOTA-FAPI-04 PET/CT与[18F]FDG PET/CT相比,显示出明显更高的损伤级敏感性 (75%与13%,P=0.002) 和精度 (80%与27%,P<0.001).
参与者对FAPI PET/CT的敏感度为100% (7/7) 与FDG PET/CT的14% (1/7) 相比 (P=0.003).
FAPI成像独特地发现了7个小的宫淋巴结转移 (平均直径5.9毫米).

结论:

[18F]AlF-NOTA-FAPI-04 PET/CT与[18F]FDG PET/CT相比,在检测复发性DTC中的小转移性病变方面提供了卓越的诊断性能.
这种先进的成像技术有可能促进早期诊断,并指导更有效的患者管理策略.

Positron 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...
