Automated segmentation of liver segment on portal venous phase MR images using a 3D convolutional neural network

Abstract: Objective We aim to develop and validate a three-dimensional convolutional neural network (3D-CNN) model for automatic liver segment segmentation on MRI images. Methods This retrospective study evaluated an automated method using a deep neural network that was trained, validated, and tested with 367, 157, and 158 portal venous phase MR images, respectively. The Dice similarity coefficient (DSC), mean surface distance (MSD), Hausdorff distance (HD),… Show more

“…The key challenge for naïve segmentation models is the lack of distinct boundaries and edge information between any two adjacent subregions. Deep learning networks have been used for the zonal segmentation of several anatomical structures [ 18 , 19 , 20 ]. The performance of these techniques largely depends on the segmentation approach adopted.…”
