FAPI PET has been developed as a promising approach for the evaluation of fibroinflammatory, such as in inflammatory bowel disease. This prospective study aims to explore the value of 18F-AlF-FAPI PET/CT in assessing the activity of Thyroid Eye Disease (TED) and investigate whether FAPI PET/CT may be superior to 99mTc-DTPA SPECT/CT for the diagnosis, therapy response assessment, and follow-up of TED.
