2. Fig 1
Location of area and diameter measurements of the thoracic aorta: 1 = maximum ascending aorta diameter; 2 = at the left subclavian artery; 3 = at 2 cm beyond the left subclavian artery; 4 = 10 cm beyond the left subclavian artery, 5 = the widest part of the descending thoracic aorta; and 6 = at the level of the celiac axis.

3. Fig 2
(A) Views used to measure the thoracic aorta using the 3-mensio system. The central luminal line is installed which (left) allows a “stretch view” to be produced (left). This allows accurate determination of anatomic landmarks and precise location of measurements. (B) Diameters and areas are measured using multiplanar reconstructions of the computed tomographic images in the plane perpendicular to the central luminal line using the appropriate measurement tools.

4. Fig 3
(A) Scatter plot of area and diameter in the descending thoracic aorta (DTA) plotted with the line of best fit according to the linear model displayed. (B) A scatter plot of observed diameter (black) values plotted against the fitted values of the regression model from the descending thoracic aorta based on corresponding diameter.

5. Fig 4
(A) Scatter plot of area and diameter 10 cm from the left subclavian artery (LSA) plotted with the line of best fit according to the linear model displayed. (B) A scatter plot of observed diameter (black) values plotted against the predicted values of the regression model 10 cm from the LSA based on corresponding diameter. (FL = false lumen.)

6. Fig 5
(A) Scatter plot of the true lumen (TL) area and diameter at the celiac trunk (CT) plotted with the line of best fit according to the linear model displayed. (B) A scatter plot of observed TL diameter (black) values plotted against the predicted values of the regression model at the celiac axis based on corresponding diameter.

A comparison of different regression models fitted to a scatter plot of diameter versus area. Coefficients for each model were significant to the p < level. (○ = observed; — = linear; • — • = quadratic; – = exponential.)
