^†, the best results. LDCT, low-dose computed tomography; RED-CNN, residual encoder-decoder convolutional neural network; CPCE, conveying path-based convolutional encoder-decoder; WGAN, Wasserstein general adversarial network; NLnet, nonlocal network; AGC-LSRED, adaptive global context-based long-short residual encoder-decoder.
