Table 5 Difference in SUV ratios compared to the background SUV in tumor lesions (n = 108)

From: Deep learning-based image quality improvement of 18F-fluorodeoxyglucose positron emission tomography: a retrospective observational study

   cPET Mean ± SD dPET Mean ± SD P-value
Lesions SUV max ratio 3.42 ± 2.32 4.95 ± 3.26 < 0.0001
SUV mean ratio 1.49 ± 0.73 1.52 ± 0.69 0.09
SUV peak ratio 2.81 ± 2.05 3.09 ± 2.26 < 0.0001
