Dynamic
contrast enhanced (DCE) MRI and F18-fluorodeoxyglucose (FDG) PET/CT was
performed on control and pioglitazone-treated atherosclerotic New Zealand
White Rabbits at three time points over three months. After three months,
treated animals showed decreased MRI contrast agent uptake in plaque as well
as decreased FDG signal as compared to controls. Macrophage specific
immuno-histochemistry validated anti-inflammatory observations.
