Head-to-head Comparison of Diagnosis Value of Pulmonary Fibrosis on 68Ga-FAPI-04 and 18F-FDG 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 pulmonary fibrosis by PET/CT.

Intravenous injection of one dosage of 4.44-5.55 MBq(0.12-0.15mCi)/Kg 18F-FDG. Tracer doses of 18F-FDG will be used to image lesions of pulmonary fibrosis by PET/CT.
