Synopsis

Keywords: Liver, Cancer, Deep learningWe proposed a Two-stage Progressive Attention (TPA) framework by simulating the radiologists’ decision process for hepatocellular carcinoma segmentation. The study included 400 HCC patients as an internal set and 109 patients as an external test set. To obtain sensitive and specific results, our model is divided into two stages, respectively introducing attention mechanism and residual network.
