Details and patient eligibility

About

The purpose of this study is to evaluate the safety of fibroblast activating protein receptor imaging agent [68Ga]/ Fluorine [18F] -fibroblast activating protein inhibitor (68Ga/18F-FAPI-04) in clinical application and to verify its effectiveness in the diagnosis of cardiovascular diseases.

Full description

The implementation of this project will promote the research of PET-MRI molecular imaging using the new nuclide imaging with the target of FAP combined with the MRI T1 mapping and ECV measurement technology, realize the fusion of nuclear medicine and magnetic resonance technology in a real sense, dynamically monitor the occurrence and development of myocardial fibrosis in heart failure at an early stage, and establish a complete set of myocardial fibrosis imaging programs. To provide an important basis for the exploration of anti-fibrosis therapy in heart failure and accelerate the pace of clinical transformation of this protocol.
