Table 8 SUVmax, SUVpeak, standard deviation of the background region and Contrast-to-noise ratio indexes measured on the 60 lesions selected by the physicians on PET100, PET50 and PET50 + SP series of our patients

From: Clinical and phantom validation of a deep learning based denoising algorithm for F-18-FDG PET images from lower detection counting in comparison with the standard acquisition
