Differential diagnosis of pulmonary nodules using 3D CT image

Lung cancer CT screening has been carried out. Unnecessary biopsy is performed in 20-55% of cancer candidate cases. Several malignant risk models have been published to reduce the false positive rate of lung cancer. In this study, we develop a high-performance malignant risk model. This risk model consists of Generalized Additive Model (GAM) using diameter, pleural attachment area rate, CT kurtosis, GLCM_Inertia, GLCM_IDM and GLCM_Energy_in_marginal_region. This model shows effectiveness by showing AUC 0.918 compared to the current Pancan model.
