Abstract: Fibroblast activation protein (FAP) is an important molecular marker of cancer-associated fibroblasts (CAFs). FAP is selectively expressed in more than 90% of epithelial carcinomas, but barely expressed in normal tissues. In recent years, a variety of radiolabeled molecular probes based on FAP inhibitor (FAPI) have been developed and used for imaging of malignant tumors. FAP is also highly expressed in some non-neoplastic diseases related to chronic inflammation and tissue remodeling, including arthritis, atherosclerosis, fibrosis of myocardial infarction, cirrhosis, and idiopathic pulmonary fibrosis. FAPI imaging shows a potential in these diseases. This paper reviews the current status of radionuclide labeled FAPI and the application of which in non-neoplastic diseases.
