ON THE COVER
Atherosclerosis imaging with 18F-FDG PET is useful for detecting inflammation within plaque and monitoring the response to drug therapy. Here, PET and PET/CT images of femoral artery 18F- FDG uptake on days 1 and 14 demonstrate the strong temporal reproducibility of the technique. Measurement of target-to- background ratios may prove useful for assessing both systemic and plaque-focused therapies for atherosclerosis.
