Abstract

Fibroblast activation protein inhibitor (FAPI) and [¹⁸F]fluorodeoxyglucose ([¹⁸F]FDG) provide complementary biological information, and FAPI/FDG dual-tracer imaging clinical application is increasing recently. However, optimal protocols for FAPI/FDG dual-tracer positron emission tomography/computed tomography (PET/CT) and PET/magnetic resonance (PET/MR) imaging are still under investigation. Due to its high sensitivity, total-body PET/CT allows for imaging with minimal tracer activity and supports the creation of new dual-tracer PET/CT imaging protocols. PET/MR, with its multiparametric MR imaging, provides additional biological information for diagnosis. Studies have investigated the clinical feasibility of low-activity PET/MR imaging, yielding promising results. As there are still few institutions in the world that have experience with the advances provided by the use of total-body PET/CT and equipped with a PET/MR scanner, we have discussed the clinical explorations to reduce radiation exposure and optimize workflows for [⁶⁸Ga]Ga-FAPI-04 and [¹⁸F]FDG dual-tracer PET/CT and PET/MR imaging. The review also provides potential new clinical explorations of [⁶⁸Ga]Ga-FAPI-04 and [¹⁸F]FDG dual-tracer total-body PET/CT and PET/MR imaging, including dual-tracer dual-low-activity imaging.

68Ga] Ga-FAPI-04 和 [18F] FDG 双示踪剂全身 PET/CT 和 PET/MR 成像的临床探索。

成纤维细胞活化蛋白抑制剂（FAPI）和[18F]氟脱氧葡萄糖（[18F]FDG）可提供互补的生物学信息，近年来FAPI/FDG双示踪剂成像的临床应用日益增多。然而，FAPI/FDG 双示踪剂正电子发射断层扫描/计算机断层扫描（PET/CT）和 PET/磁共振（PET/MR）成像的最佳方案仍在研究中。全身 PET/CT 具有高灵敏度，可在示踪剂活性最小的情况下进行成像，并支持创建新的双示踪剂 PET/CT 成像方案。PET/MR 及其多参数磁共振成像为诊断提供了额外的生物信息。已有研究对低活性 PET/MR 成像的临床可行性进行了调查，结果令人鼓舞。由于世界上有经验使用全身 PET/CT 并配备 PET/MR 扫描仪的机构仍然很少，我们讨论了减少辐射暴露和优化 [68Ga]Ga-FAPI-04 和 [18F]FDG 双示踪 PET/CT 和 PET/MR 成像工作流程的临床探索。综述还提供了[68Ga]Ga-FAPI-04和[18F]FDG双示踪剂全身PET/CT和PET/MR成像（包括双示踪剂双低活度成像）的潜在新临床探索。
