图1 胸骨测量平面中皮质厚度的测量 Note： A. The measurement plane at the tracheal bifurcation. The arrow points to the tracheal bifurcation. B. The calculation of the sternal cortical thickness ratio in the measurement plane. ① represents the thickness of the outer edge of the sternal cortex; ② represents the thickness of the inner edge of the sternal cortex; (①?②)/① is the sternal cortical thickness ratio.
