Targeted PET/CT and PET/MRI Imaging of Vascular Inflammation

Summary

Stroke and abdominal aortic aneurysms (AAAs) are common and highly lethal vascular diseases. Angiogenesis and infiltration of inflammatory cells such as macrophages may cause stroke and AAAs. The purpose of this study is to test PET/CT and PET/MRI imaging to specifically detect those diseases using a new developed agent (18F-FPPRGD2) that can target angiogenesis and macrophages.
