(A,B) Comparison of CT values between lepidic and non-lepidic predominant lesions. (A) Lepidic predominant lesions showed significantly lower mean CT values. (B) Lepidic predominant lesions showed significantly lower maximum CT values. (C,D) Receiver operating characteristic curve analysis for lepidic predominant lesion prediction. (C) The sensitivity and specificity of mean CT values were 77.8% and 82.8%, respectively. (D) The sensitivity and specificity of maximum CT values were 77.8% and 72.4%, respectively.
