Lesion Segmentation and RECIST Diameter Prediction via Click-driven Attention and Dual-path Connection [article]

Youbao Tang, Ke Yan, Jinzheng Cai, Lingyun Huang, Guotong Xie, Jing Xiao, Jingjing Lu, Gigin Lin, Le Lu
2021 arXiv   pre-print
In this paper, we present a prior-guided dual-path network (PDNet) to segment common types of lesions throughout the whole body and predict their RECIST diameters accurately and automatically.  ...  Experiments show the superiority of our proposed PDNet in lesion segmentation and RECIST diameter prediction using the DeepLesion dataset and an external test set.  ...  It consists of three components: an image encoder, a prior encoder with click-driven attention, and a decoder with dual-path connection.  ...
