(A) Relationship between the mean and maximum CT values. The lines indicate the optimal cutoff value for the mean CT value (− 150 HU) and the maximum CT value (380 HU). The sensitivity and specificity for lepidic predominant lesions were 77.8% and 86.2%, respectively. (B) Kaplan–Meier survival curves for disease-free survival (DFS). Patients with lepidic predominant lesions experienced no recurrences.
