Fig. 2From: The development and validation of a radiomic nomogram for the preoperative prediction of lung adenocarcinomaRadiomic workflow. Contrast-enhanced chest CT images are retrieved for radiomic feature extraction. ROIs of pulmonary nodules are segmented and the corresponding ROIs are stacked up to construct VOI of the nodules. Six categories of radiomic features are extracted from within the defined VOI, including histogram features, form factor features, and texture featuresBack to article page
