Abstract
PURPOSE OF REVIEW: Noninvasive imaging of atherosclerotic plaques has substantially advanced over the past decade such that currently available imaging techniques allow for characterization of high-risk morphological features of the plaques and quantification of the biological activity within the atherosclerotic milieu. Vascular PET/CT imaging provides insights into the biological activity of atherosclerotic plaques and, in particular, plaque inflammation. Fluoro-deoxyglucose-PET/CT imaging is currently used to improve the understanding of atherosclerotic pathophysiology, facilitate the discovery of new treatments and improve clinical prognostication in humans. RECENT FINDINGS: Several studies have evaluated the feasibility, validity and reproducibility of fluoro-deoxyglucose-PET/CT for imaging of atherosclerotic plaque inflammation. Fluoro-deoxyglucose-PET/CT imaging is demonstrated to have the potential to predict the efficacy of novel antiatherosclerotic therapeutics by using a relatively small sample size and within a relatively short time period in several multicenter trials. SUMMARY: The currently feasible assessment of inflammation within the atherosclerotic plaques has been demonstrated to enhance assessment of clinical risk, provide a better understanding of therapeutic efficacy of novel drugs, and it may provide a window into inflammation within the coronary tree. Further technological advances in PET technology have the potential to catalyze further progress in imaging of atherosclerotic plaque biology.
