[68Ga]Ga-DOTA-Siglec-9 PET/CT in newly diagnosed giant cell arteritis: an inflammation-specific, treatment-responsive molecular imaging biomarker.
Assessing disease activity in giant cell arteritis (GCA) remains challenging, as existing clinical, laboratory and imaging biomarkers lack specificity. This proof-of-concept study explored the diagnostic potential of vascular adhesion protein-1 (VAP-1) targeting [68Ga]Ga-(1,4,7,…
