- 核医学就是核医学.
- 放射学 放射学是一门学科.
背景情况:
- 在选择非小细胞肺癌 (NSCLC) 患者进行手术时,中节点分期至关重要.
- 传统的成像方法往往有局限性,导致需要侵入性分期程序.
- 纤维细胞激活蛋白抑制剂 (FAPI) PET/CT是一种新兴的成像技术,针对纤维细胞激活蛋白.
研究的目的:
- 调查[68Ga]FAPI-46 PET/CT在NSCLC中中枢结节分期的临床附加值.
- 为了比较[68Ga]FAPI-46 PET/CT与[18F]FDG PET/CT的诊断性能,用于识别N2疾病.
主要方法:
- 一项前性试点研究招募了符合侵入性分期特定标准的NSCLC患者.
- [68Ga]FAPI-46 PET/CT是在标准的[18F]FDG PET/CT之后进行的.
- 诊断准确性通过每位患者和每个病房的分析来评估,使用病原体作为参考标准.
主要成果:
- 组织病理学证实了23名患者中9名患者的N2阳性.
- [68Ga]FAPI-46 PET/CT在检测转移方面表现出高灵敏度 (0.89),与[18F]FDG PET/CT相比,提高了3名患者的诊断阶段.
- 每站分析显示[68Ga]FAPI-46 PET/CT (AUC 0.96) 与[18F]FDG PET/CT (AUC 0.68) 的转移有更好的区别.
结论:
- [68Ga]FAPI-46 PET/CT显示了在NSCLC中进行手术前的中枢结节分期的显著前景.

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...
