Fig 1 Radiographic factors included in the risk model were (A) blunt traumatic aortic injury (BTAI) lesion maximal width, (B) normal aortic diameter, and (C) width of the dependent mediastinal hematoma along the descending thoracic aorta.

Fig 2 Aggregate score point distributions for the rupture and stable groups. The average scores are 6 ± 1 for rupture group and 2 ± 2 points for the stable group. A cutoff of ≥4 points was 100% sensitive, 84% specific, and 100% accurate for identifying lesions that were at high risk for aortic rupture.
