Presence or absence of 18F-Fluoride PET signal is denoted (+ and – respectively) for each individual valve leaflet. The distribution of 18-Fluoride signal on scan 1 images (1a) were reassessed (1b) to assess intraobserver reproducibility and compared to scan 2 (2) to determine scan-rescan reproducibility.
