About this trial
This study intends to use the new technology of fibroblast activation protein PET / CT to study whether the tiny residual lesions detected by 68Ga-FAPI PET / CT are related to the recurrence of IgG4-RD in patients with IgG4-RD who have been clinically evaluated for complete remission after treatment.
