Table 1.
Differences of the SUVmean, SUVmax, and SUVpeak values between the FullTime-PET and the AI-ExtremePET images for each model based on the original lesion segmentation mask. The SUVmean is calculated based on the mean SUV values present within the lesion mask. The SUVmax is calculated using the maximum SUV value for each lesion mask. The SUVpeak is calculated using a 1-cm3 sphere around the maximum voxel within a lesion mask
