Systemic sclerosis (SSc) is a multi-system disease characterized by immune dysregulation, fibrosis and vascular damage that affects the gastrointestinal tract in most patients. In this study, we investigate simultaneous FDG-PET/MR imaging for the diagnosis of SSc GIT involvement. Our preliminary results show that FDG-PET can detect inflammation in the bowels while T1 MOLLI mapping could be able to distinguish healthy from fibrotic GIT tissue.
