PET imaging offers a non-invasive approach to measure biological processes like arterial inflammation and calcification in atherosclerosis.
Positron emission tomography (PET) provides a non-invasive method to measure biological processes that are relevant to atherosclerosis, including arterial inflammation and calcification. The vast majority of studies imaging atherosclerosis with PET have utilized the tracer 18 F-fluorodeoxyglucose (FDG) to better understand how inflammation contributes to atherosclerosis development, and to test the efficacy of therapeutic interventions aimed at reducing its progression. Additional tracers such as 18 F-sodium fluoride ( 18 F-NaF) provide additional avenues for characterizing atherosclerosis development. This review examines the emerging uses of PET arterial imaging as a marker of vascular inflammation and atherosclerosis, as a prognostic tool, and as a clinical research tool. In addition, we examine emerging methods that should advance arterial imaging with PET.
