Fisher's exact test and odds ratio with its 95% confidence interval were used to analyze the relationship of pulmonary artery to lesion with the possibility of malignancy. The degree of pulmonary arterial encasement in the benign lesion and malignancy was evaluated by Wilcoxon rank sum test. The agreement between 2 observers was evaluated by kappa statistics. In addition, the sensitivity and specificity profiles of the degree of encasement in diagnosis of malignancy were determined by plotting an empirical ROC curve.
