Fig. 6A —Distribution of lesion sizes. Graphs show distribution of lesion mean diameters for benign (circles, n = 120) versus malignant (triangles, n = 107) transient hepatic attenuating masses (A) and corresponding receiver operator characteristic curves (B). In plot (A), horizontal line at 22 mm indicates threshold diameter above which all masses are benign. On ROC curve (B), several diameter thresholds (in mm) are marked at inflection points. Area under curve (AUC, 0.676) is significantly higher than uninformative AUC of 0.50 (area under dashed line).
