Anti-Inflammatory Effects of Pioglitazone

Summary

There is increasing evidence that inflammation plays a role in progression and destabilization of atherosclerotic plaque. FDG-PET can visualize activated metabolic activity of inflammatory cells. It is possible that FDG-PET can detect atherosclerotic plaque inflammation and that FDG-PET can monitor the effect of pioglitazone on plaque inflammation.
