Research on the Application of 99mTc-TCR-FAPI SPECT Imaging in Rheumatoid Arthritis

"For 68Ga-FAPI PET/CT scan，each patient was injected with 1.8-2.2 MBq/kg (0.05-0.06 mCi/kg) body weight of 68Ga-FAPI. PET/CT from skull to feet was performed 60±5 min post-injection.~For 99mTc-CTR-FAPI SPECT scan:each patient was injected with 10-20mCi 99mTc-CTR-FAPI . Planar SPECT scan and SPECT/CT were performed 60±5 min post-injection."
