Figure 6.

Graphs A show that the low BV group has higher attenuation than the high BV group in the control group. Graph B shows that point A and point B have the same BMI in the control group, point A is a female patient with a height of 156 cm, weight of 55 kg, BV 3.35 L, and aortic root attenuation of 875 HU; point B is a male patient with the height 172 cm, weight 67 kg, BV4.6 L, and aortic root attenuation of 486 HU. Graph C shows that the patients above the third quartile BV in the experimental group still meet the requirement.
