  1. Summary of lesion measurements from simulations of hot lesion against colder background with a range of random noise levels added (see Figure 5). Numbers represent average measurements from a single gate of 500 simulations for each noise scenario. All measurements are presented as a percentage of the corresponding true noise-free values. The standardized uptake value (SUV) was calculated from for 70% threshold volume.
