概括
-18-FAPI PET/CT成像显示出评估慢性病 (CKD) 严重程度的前景. 这种先进的成像技术与功能有很好的相关性,为诊断和治疗指导提供了一个新的工具.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 核医学就是核医学.
- 放射化学 放射化学是指辐射化学.
背景情况:
- 慢性病 (CKD) 的进展是由纤维化驱动的,其特征是异常的细胞外基质积累.
- 像MRI和超声波弹性图像等先进的成像技术提供了对纤维化的非侵入性评估.
- 纤维细胞激活蛋白 (FAP) 向成像,特别是用Fluorine-18标记的标记物 (F-FAP),正在成为纤维化疾病的工具.
研究的目的:
- 评估F-FAP正子发射断层扫描/计算机断层扫描 (PET/CT) 成像用于诊断和量化CKD患者纤维化的实用性.
- 为了确定脏F-FAP吸收和CKD的严重程度之间的相关性,根据膜过率 (GFR) 评估.
- 探索F-FAP PET/CT作为抗纤维菌疗法的非侵入性诊断和治疗指导工具的潜力.
主要方法:
- 分析了来自100名CKD患者的正子发射断层扫描数据 (2022年10月至2023年9月).
- -18-FAPI-04的合成和使用飞利浦创新TF PET/CT扫描仪的成像.
- 使用最大标准化吸收值 (SUVmax) 和SUV平均值 (SUVmean) 来量化脏放射追踪剂分布.
- 脏放射标志物吸收与CKD阶段和GFR的相关性.
主要成果:
- 在GFR和脏F-FAP吸收之间观察到一个复杂的关系,并指出了显著的相关性 (P<0.001).
- 脏SUVmax和SUV平均值的F-FAPI C显示出具有统计意义.
- 对比分析表明F-DOPA和Ga-PSMA的显著SUVmax值18和68,表明不同的放射性痕迹吸收模式.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
74
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...
