Evaluating a new imaging method for Thyroid Eye Disease

Exploring the Value of 18F-AlF-FAPI PET/CT in Assessing the Activity of Thyroid Eye Disease

NA · Peking University Third Hospital · NCT06359795

This study is testing a new imaging method to see if it can better assess the activity of Thyroid Eye Disease compared to the traditional imaging technique for patients with this condition.

What this trial studies

This study investigates the effectiveness of 18F-AlF-FAPI PET/CT in assessing the activity of Thyroid Eye Disease (TED) compared to the traditional 99mTc-DTPA SPECT/CT. Patients diagnosed with TED will undergo both imaging techniques within a 10-day period to evaluate their diagnostic accuracy and ability to assess therapy response. The study will quantify uptake in the extraocular muscles and correlate these metrics with clinical activity data to determine the superiority of the new imaging method. The goal is to enhance the diagnosis and management of TED through improved imaging techniques.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have been diagnosed with Thyroid Eye Disease.

Not a fit: Patients with severe liver or kidney dysfunction, or those unable to cooperate with the imaging procedures, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate assessments and better management of Thyroid Eye Disease for patients.

How similar studies have performed: While FAPI PET has shown promise in other fibroinflammatory conditions, this specific application for Thyroid Eye Disease is novel and has not been extensively tested.
