Figure 1. — Patients with primary aldosteronism (PA) display enhanced vascular wall inflammation.

A, Vascular inflammation was measured in 5 regions of interest (ROIs): the carotid arteries, the wall of the ascending, descending and abdominal aorta, and the iliac arteries. To calculate the target-to-background ratio (TBR), the blood pool in the low thoracic artery was used as background. B, In patients with PA, the carotid arteries have a significantly higher maximal and mean TBR. C, No differences in uptake were seen in the wall of the ascending aorta. D, In the wall of the descending aorta, mean and maximal TBR were significantly higher in patients with TBR; E, the same holds true for the mean TBR of the wall of the abdominal aorta, F, as well as for the mean and maximal TBR of the iliac arteries. TBR, target-to-background ratio. *P < .05; **P < .01.
