The columns represent the low-dose healthy controls, the low-dose patients, and the ultra-low-dose controls, respectively. Each row represents the average absolute difference in SUV-r value from the normal dose in a cortical region, expressed as a percentage, with the range in parentheses. All mean values higher than 3% are marked in bold for easy reference. Post cing=posterior cingulate gyrus.
