Analyse of Diagnosis Value of Keloid on 68Ga-RGD PET-CT

June 17, 2026 updated by: Peking Union Medical College Hospital
Keloids are often described as benign dermal fibroproliferative lesions characterized by increased growth beyond the boundaries of the original wound margin.Fibroblasts are considered to be the key cellular mediators of fibrogenesis in keloid scars. Thus this prospective study is going to investigate whether 68Ga-RGD PET/CT may provide evidence for diagnosis and evaluate the effectiveness of treatment.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 68Ga-RGD PET/CT
All patients diagnosed with keloid underwent 68Ga-RGD PET/CT.
Intravenous injection of one dosage of 18.5-22.2MBq (0.5-0.6 mCi)/Kg 68Ga-FAPI. Tracer doses of 68Ga- FAPI will be used to image lesions of keloid by PET/ CT.
