Summary

Systemic sclerosis (SSc) is a heterogeneous clinical picture consisting of inflammatory, vasculopathic, and fibrotic changes. Initially, inflammatory changes usually occur, which result in fibrosis over time. This affects various organ systems such as the lungs, skin, heart, and gastrointestinal tract. Early detection of inflammatory activity is therefore important in order to prevent consequential damage, in particular irreversible fibrosis. Since the inflammatory foci can spread throughout the entire body, there is a need to be able to detect inflammatory activity over a large area. The 68Ga-Pentiafor-based imaging of the CXCR4 chemokine receptor, which is expressed on immune system cells such as lymphocytes and macrophages, among others, offers a useful approach here, as it allows specific inflammatory cells that migrate to inflammatory lesions via the corresponding ligand (CXCL12) and are involved in the pathogenesis of SSc. To date, only chest CT has been used to diagnose and monitor the progression of pulmonary fibrosis in SSc. This non-functional imaging makes it virtually impossible to draw conclusions about inflammatory activity.
