Progression from healthy arteries to complicated lesions. FDG and NaF uptake have long been known to precede vascular calcification evident on CT and intravascular ultrasonography (IVUS) [5, 6]. The paradigm shift is the stronger predictive power of NaF uptake and the occurrence of active calcification measured by 18F-NaF uptake in early coronary fatty streaks and preatheroma (CAC coronary artery calcium)
