Figure 3:

Response status on (A) conventional and (B) deep learning (DL)–enhanced simulated fluorine 18 (18F) fluorodeoxyglucose (FDG) PET scans. (A) Bar chart shows that reducing the radiotracer dose to less than or equal to 75% leads to a significant underestimation of tumor therapy response and erroneous upstaging of adequate responders to inadequate responders on simulated reduced-dose 18F-FDG PET images (P < .05). (B) Bar chart shows that simulated dose reduction with DL-enhanced 18F-FDG PET scans enables dose reduction up to 50% with correct therapy response assessment of all patients.
