Imaging tumor microenvironment: clinical experience with 68Ga-FAPI PET/CT across multiple cancer types

⁶⁸Ga-FAPI-46 PET/CT provides high-contrast imaging across a wide spectrum of malignancies, demonstrating particularly strong potential for visualizing tumors with prominent stromal components. These findings suggest a significant clinical role for this modality in improving tumor staging, restaging, and therapy assessment, especially in cases where ¹⁸F-FDG PET/CT is suboptimal.
