    Line chart showing the mean aorto-vertebral angles measured at each vertebral level in the control group (green line), scoliosis patients with right curve (blue line), and scoliosis patients with left curve (red line). The 3 lines are furthest at the level of apex vertebra (T7) and closest at T11 to T12; the level of the diaphragmatic aortic hiatus is shown.
