Yaping Luo 1 2, Qingqing Pan 1 2, Huaxia Yang 3, Linyi Peng 3, Wen Zhang 3, Fang Li 4 2 Abstract: IgG4-related disease (RD) is characterized by lymphoplasmacytic infiltration enriched in IgG4-positive plasma cells and variable degrees of fibrosis with a characteristic storiform pattern. Since fibrosis is an important feature of IgG4-RD, we performed a prospective cohort [...]

Patrick Conen 1 2, Felix M Mottaghy 3 4 5 Purpose: Cancer-associated fibroblasts (CAFs) expressing fibroblast activation protein (FAP) have been associated with the aggressive nature of head and neck cancers (HNCs). These tumours grow diffusely, leading to extremely challenging differentiation between tumour and healthy tissue. This analysis aims to introduce [...]

Liang Zhao 1, Jianwei Gu 2, Kaili Fu 1, Qin Lin 1, Haojun Chen 2 Abstract: Ga-FAPI PET/CT was performed in a 56-year-old cirrhotic patient with multiple liver nodules, which were suspected of hepatocellular carcinoma by contrast-enhanced magnetic resonance but were not visualized by F-FDG PET/CT. Increased Ga-FAPI liver uptake was observed in [...]
