- The data are shown as the mean and standard deviation. Note: The current DCNN is trained to be used only for general whole-body studies but is not designed for the brain. cPET, conventional positron emission tomography; dPET, deep learning processed positron emission tomography; SD, standard deviation; SUV, standardized uptake value
