From: Prediction of distant metastasis in esophageal cancer using a radiomics–clinical model
Procedure for creating a radiomics signature. From the 851 radiomic features extracted from CT-ROIs, the Lasso algorithm selected 16 features that had the best correlation with distant metastasis and constructed the radiomic signature. The box chart and bar plot revealed that there was no significant difference between the training and validation sets, but there was a difference between patients with and without metastasis
