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

Summary

This study proposes to evaluate 99mTc-CTR-FAPI SPECT imaging as a cost-effective, low-radiation, and widely accessible alternative to 68Ga-FAPI PET/CT for assessing synovial lesions in RA patients, aiming to validate its diagnostic consistency with both PET/CT and physical examinations while correlating imaging findings with clinical disease activity metrics to establish a practical tool for long-term RA monitoring.
