Maps of diffusion kurtosis imaging scalar measures using different methods. Note. High-quality diffusion kurtosis imaging (DKI) scalar maps with the model-fitting method in the first line, moderate-quality DKI scalar maps with the model-fitting method in last line, and moderate quality of DKI scalar maps with the convolutional neural network (CNN) method in the middle line indicate that the CNN-based method can optimize the scalar maps of moderate diffusion-weighted images
