Fig. 2From: 18F-labeled tracers targeting fibroblast activation proteinSmall animal PET imaging. The white arrow indicates the site of the xenotransplanted tumor. Shown are the maximum intensity projections (A, C) and time-activity curves (B, D) of selected organs in case of [18F]AlF-FAPI-74 (A, B) and [18F]AlF-FAPI-75 (C, D). Experiments were conducted in nude mice transplanted with HT-1080-FAP cells and images were acquired in the indicated time periods after tracer administrationBack to article page
