Abstract:
This study aimed to determine the potential of radiomic features extracted from preoperative computed tomography to discriminate malignant from benign indeterminate small ( ≤ 10 mm) pulmonary nodules. Methods A total of 197 patients with 210 nodules who underwent surgical resections between January 2011 and March 2017 were analyzed. Three hundred eighty-five radiomic features were extracted from the computed tomographic images. Feature selection and data dimension reduction were performed using the Kruskal-Wallis test, Spearman correlation analysis, and principal component analysis. The random forest was used for radiomic signature building. The receiver operating characteristic curve analysis was used to evaluate the model performance. Results Fifteen principal component features were selected for modeling. The area under the curve, sensitivity, specificity, and accuracy of the prediction model were 0.877 (95% confidence interval [CI], 0.795–0.959), 81.8% (95% CI, 72.0%–90.9%), 77.4% (95% CI, 63.9%–89.3%), and 80.0% (95% CI, 72.0%–86.7%) in the validation cohort, respectively. Conclusions Computed tomography–based radiomic features showed good discriminative power for benign and malignant indeterminate small pulmonary nodules.
