概括
新的[68Ga]Ga-CTR-FAPI PET-CT与[18F]FDG PET-CT.CT相比,可以更好地检测甲状腺髓癌 (MTC). 这种先进的成像技术提高了诊断准确度,并为MTC患者提供了个性化的治疗策略.
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:
- 髓性甲状腺癌 (MTC) 需要完全切除转移性病变才能治愈.
- 目前的诊断方法未能在29-60%的MTC患者中定位疾病.
- 基于纤维细胞激活蛋白抑制剂 (FAPI) 的共价向放射性对象 (CTR) 显示出对增强成像的承诺.
研究的目的:
- 在患有MTC的患者中,比较[68Ga]Ga-CTR-FAPI PET-CT与[18F]氧葡萄糖 ([18F]FDG) PET-CT的诊断性能.
- 评估[68Ga]Ga-CTR-FAPI PET-CT对患者管理和手术规划的影响.
主要方法:
- 在50名MTC患者中进行了第一类临床试验,比较了[68Ga]Ga-CTR-FAPI PET-CT和[18F]FDG PET-CT.
- 主要终点:基于患者的检测率.
- 二级终点:瘤吸收率 (SUVmax) 和通过病理学验证的诊断准确性.
主要成果:

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...
