FDG signal associations with thrombus neutrophils and macrophages. (A) The number of thrombus neutrophils correlated with the FDG uptake in DVT (SUV; r=0.41, p=0.004, TBR; r=0.62, p<0.001). (B) Thrombus macrophages pooled from day 7 and day 14 did not significantly correlate with the FDG-DVT signal (SUV; r=-0.15, p=0.47, TBR; r=0.26, p=0.23). (C) Sub-analysis of macrophages at day 14 also did not significantly correlate with FDG-DVT signals (SUV; r=0.04, p=0.91, TBR; r=0.30, p=0.37). MAC= macrophage.
