Fig. 4From: CT radiomics facilitates more accurate diagnosis of COVID-19 pneumonia: compared with CO-RADSReceiver operating characteristic curve (ROC) analysis for the clinical model and combined radiomics model in the training cohort (a) and validation cohort (b). The diagnostic performance of the combined radiomics model in distinguishing COVID-19 from pneumonia with other pathogens was better than that of the clinical model in both training and validation cohortsBack to article page
