Fig. 1. Visual assessment of PET/MRI disease activity in LVV.
Degree of FDG uptake based on visual comparison between arterial territories of interest and the liver in those with clinically determined active (red, n = 23) and inactive (blue, n = 17) disease. FDG uptake was greater in active vs. inactive disease in all aortic territories (ascending aorta, P = 0.003; aortic arch, P = 0.02; descending thoracic aorta, P = 0.03; abdominal aorta, P = 0.03), brachiocephalic artery (P = 0.03) and subclavian arteries (P = 0.04). Data are presented as mean values ±SD. Analysis by two-way ANOVA with Šidák’s multiple comparison test. Asc. aorta ascending aorta, desc. thor. aorta descending thoracic aorta.
