Table 1 (abstract A30). The average SUVmax, average SUVmean and GCS of each vascular segment of thoracic aorta in our total sample including 124 subjects, and the two subgroups of healthy subjects and patients with high risk of atherosclerosis. The P-value column represents the significance of the differences between the healthy and patients groups (SUV: standardized uptake value, AR: aortic arch, AA: ascending aorta, DA: descending aorta, GCS: Global Calcification Score)
