Abstract

Radiolabeled fibroblast activation protein inhibitors (FAPIs) are a novel approach in cancer detection and treatment. Targeting fibroblast activation protein, extensively produced by cancer-associated fibroblasts, FAPI plays a key role in tumor development. Its advanced imaging capabilities offer clearer results in solid tumors compared with traditional methods, drawing significant interest in oncology. Additionally, FAPI's activity in conditions requiring tissue remodeling, such as atherosclerosis and arthritis, highlights its broader potential. This interesting image shows the physiological accumulation of 68 Ga-FAPI in the gallbladder, emphasizing the importance of accurate interpretation to prevent misdiagnoses and ensure effective patient management.
