摘要
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.
