Molecular Imaging of the Underlying Mechanism of Vessel Wall Inflammation Using Positron Emission Tomography (PET/CT)

This research study is being conducted to test how an imaging drug called 64Cu-DOTA-ECL1i can be used to image an abdominal aortic aneurysm. 64Cu-DOTA-ECL1i is a drug used with an imaging test called a PET/CT (Positron Emission Tomography/Computed Tomography). The aim is to collect data using a new imaging drug called 64Cu-DOTA-ECL1i that may be able to create images of inflammation in the aorta, which is thought to be important in how aneurysms grow and develop and to understand how consistent these scans are across time and what might affect the inflammation.
