Learning to Jointly Segment the Liver, Lesions and Vessels from Partially Annotated Datasets

Abstract

The segmentation of the liver, lesions, and vessels from pre-opera-tive CT scans is of major importance in hepatic surgery planning. However, large databases with reference segmentations for these regions of interest remain unavailable, a challenge often encountered in medical image segmentation. In this work, we propose the FuSeloss, a novel loss function for multi-task learning on datasets with partial annotations. By employing the nnU-Net’s 3D self-configur-ing pipeline to calibrate and train a deep network for the joint segmentation of the liver, lesions, and vessels, we show how the FuSe loss allows to learn from the differently annotated IRCAD and LiTS datasets, improving the overall baseline segmentation performance. With the FuSe loss, the dice scores reached up to 95.9%, 70.6% and 60.0% for the liver, lesions, and vessels respectively.
