An overview of liver segmentation

The authors of this article aim to deliver to radiologists and other healthcare professionals an accessible overview of liver segmentation to assess the liver volume.

Teaching points:

  • Liver volume is assessed via organ segmentation on CT and MRI examinations.
  • Liver segmentation is used for volume assessment prior to major hepatic procedures.
  • Segmentation approaches may be categorised according to the amount of user input involved.
  • Emerging applications include surgical planning and integration with MRI-based biomarkers.


Liver volumetry has emerged as an important tool in clinical practice. Liver volume is assessed primarily via organ segmentation of computed tomography (CT) and magnetic resonance imaging (MRI) images. The goal of this paper is to provide an accessible overview of liver segmentation targeted at radiologists and other healthcare professionals.
