Comparison of 6 patients with IgG4-related disease (IgG4-RD) undergoing FDG and FAP-specific PET. FAP-specific PET detected IgG4-RD in the pancreas (patient #1, 2, 3, 4) bile duct/liver (patient #1, 2, 3), retroperitoneal fibrosis (patient #5), lung/pleura (patient #6), and salivary gland (patient #1, 3). Positive Iymph nodes on FDG PET show no enhancement on FAP-specific PET (patient #2, 3) (Fig. 2). This research was originally published in JNM. Luo et al.
