"use": {
"title": "Intended Use",
"text": "This model is intended to perform liver segmentation in CT scans. The model has been trained and tested on scans aquired during clinical care of patients, so it might not be suited for a healthy population. The generalization capabilities of the model on a range of ages, genders, and ethnicities are unknown."

"text": "The model's performance was assessed using the Dice Coefficient and Normalized Surface Distance (NSD) with tolerance 7mm, as specified in the CT Liver segmentation task in the Medical Segmentation Decathlon challenge. The model was used to segment cases from the IDC collection TCGA-LIHC [1]. Seven of those cases were reviewed and corrected by a board-certified radiologist and a non-expert. The analysis is published here [2]",
