1 Thoracic and abdominal aortic dimension in 70-year-old men and women – A population-based whole-body magnetic resonance imaging (MRI) study  Anders Wanhainen, MD, PhD, Raquel Themudo, MD, Håkan Ahlström, MD, PhD, Lars Lind, MD, PhD, Lars Johansson, MD, PhD  Journal of Vascular Surgery  Volume 47, Issue 3, Pages (March 2008) DOI: /j.jvs Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Maximum intensity projection of the aorta with the corresponding survey slices of the (a) ascending aorta, (b) descending aorta, (c) supraceliac aorta, (d) suprarenal aorta, (e) infrarenal aorta, and (f) aortic bifurcation.

3 Fig 2 Box-and-whisker plot of aortic diameter determined by means of whole-body magnetic resonance angiography in 231 subjects, showing the 2½%, 25%, 50%, 75%, and 97½% cumulative relative frequencies. Open circles represents cases with values box lengths from the upper or lower edge of the box and stars represents cases with values >3 box lengths from the upper or lower edge of the box.

4 Fig 3 Scatter-plot of ascending aorta diameter (cm) and body surface area (BSA, cm2). For men (a) the regression line is y = × 10−5 × BSA (R2 = 0.13, P < .001) and for women (b) y = × 10−5 × BSA (R2 = 0.06, P = .013), where y is ascending aortic diameter (dotted line is y + 2 SD).

5 Fig 4 Scatter-plot of descending aorta diameter (cm) and body surface area (BSA, cm2). For men (a) the regression line is y = × 10−5 × BSA (R2 = 0.11, P < .001) and for women (b) y = × 10−5 × BSA (R2 = 0.11, P < .001), where y is descending aortic diameter (dotted line is y + 2 SD).

6 Fig 5 Scatter-plot of infrarenal aorta diameter (cm) and body surface area (BSA, cm2). For men* (a) the regression line is y = 2.9 − 2.5 × 10−5 × BSA (R2 = 0.02, P = .19) and for women (b) y = × 10−5 × BSA (R2 = 0.03, P = .055), where y is infrarenal aortic diameter (dotted line is y + 2 SD). *Three extreme outliers (diameter >4 cm and ratio >1.4) were excluded from the calculation and is not shown in the scatter-plot.

7 Fig 6 Box-and-whisker plot of the ratio between different aortic segments and the suprarenal diameter, showing the 2½%, 25%, 50%, 75%, and 97½% cumulative relative frequencies. Open circles represents cases with values between 1.5 and 3 box lengths from the upper or lower edge of the box, and stars represents cases with values more than 3 box lengths from the upper or lower edge of the box.
