Use of a Radiomics Model to Predict Tumor Invasiveness of Pulmonary Adenocarcinomas Appearing as Pulmonary Ground-Glass Nodules

Figure 4

Receiver operating characteristic curve for the prediction of the radiomic nomogram. ROC is based on the combination of the 95th percentile pure or mixed lesions (PM) and fractal dimension (FD) and shows significant diagnostic accuracy in both primary and validation cohorts. AUC for the primary (a) and validation cohorts (b) was 0.757 (95% CI: 0.711 to 0.803) and 0.793 (95% CI: 0.708-0.877), respectively.
