¹⁸FAlF-NOTA-FAPI-04 PET/CT provides a noninvasive, integrative imaging platform for mapping fibroblast activation across multiple organs in SSc. It demonstrated potential for detection of fibrotic burden and inter-organ metabolic profiling. Its sensitivity in gastrointestinal and cutaneous involvement remains limited, warranting further optimization.
Wang et al. (2025) studied this question.
