[68Ga]Ga-FAPI-46 PET for Visualization of Postinfarction Renal Fibrosis

Fibroblast activation protein (FAP)–targeted PET imaging is promising for cancers with a high content of cancer-associated fibroblasts ([1][1] , [2][2]). However, FAP is also expressed by activated fibroblasts involved in multiple fibroinflammatory nononcologic conditions. FAP is involved in
