What this trial studies

This study investigates the diagnostic value of 68Ga-FAPI PET/CT compared to 18F-FDG PET/CT in patients with pulmonary fibrosis. It aims to determine if 68Ga-FAPI, which targets activated fibroblasts, is more effective in assessing the severity of the disease and monitoring therapy response. The study will involve patients who have suspected or confirmed pulmonary fibrosis and will require their consent to participate. By conducting a head-to-head comparison, the research seeks to provide insights into the most effective imaging modality for this condition.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy and treatment monitoring for patients with pulmonary fibrosis.

How similar studies have gone: Preliminary research suggests that FAPI-PET/CT imaging may be more sensitive than FDG-PET/CT for certain inflammatory conditions, indicating potential success for this approach.
