Abstract:
68Ga-FAPI is a newly developed tumor imaging agent with promising clinical applications. However, benign lesions may also show increased FAPI activity. We accidentally discovered that Schmorl node expressed FAPI activity in a patient with sweat gland cancer. Thus, greater awareness is needed that Schmorl nodes are a potential reason for false-positive uptake on 68Ga-FAPI PET/CT.
