Fig. 2A. —Relationships between aortic image noise and body size.
Scatterplots show relationships calculated on basis of body weight (A)
as y = –1.42 – 0.013 x x; R2 =
0.619 and scout image data (B); y = –0.411 – 0.016
x x; R2 = 0.812. Vertical axis indicates Ln[1 /
(aortic image noise)2]. Coefficient of determination
(R2) was higher when body size was evaluated on basis of scout
image data.
