Figure 2:

Synthesized low dose brain FDG PET imaging using undersampling from list mode data. Such methods are a conservative way to estimate images produced with lower injected doses and can be used to train a deep network to predict the full-dose PET. At 200x reduced dose, a typical FDG PET brain examination could be performed at a radiation dose comparable to the excess amount of radiation one would accrue on a cross-USA airplane flight.
