18F-NaF PET-CT Predicts Disease Progression in AS
Baseline CT calcium score scans (left) for patients 1 (A) and 2 (B). Fused 18F-NAF PET-CT scans (middle) show fluoride uptake in red and yellow. Follow-up CT at 1 year (right) suggests that the baseline PET signal predicts where new macroscopic calcium, visible on the CT, is going to develop. Reproduced with permission from Dweck et al. (45). AS = aortic stenosis; other abbreviations as in Figures 1 and 2.
