The measurements of variables that quantified descending thoracic aortic remodelling on the erect posteroanterior chest radiograph: (a) measurement of lateral displacement; (b) measurement of curvature angle.

3. Fig 2
Correlations of (a) lateral displacement and (b) curvature angle measured on chest radiograph with a maximum lateral distance of the aorta measured on computed tomography (CT). Data are collected from 32 patients, with 10 from the 70 patients of the present study.

4. Fig 3
Variability in oesophageal Doppler monitor (ODM) readings over a 10-cm probe depth range as aorta unfolding increased, quantified by the (a) lateral displacement and (b) curvature angle measurements from erect posteroanterior chest radiograph. Regression lines and equations were shown. CV: coefficient of variation; SV: stroke volume.

5. Fig 4
Receiver operating characteristic (ROC) curves showing the ability of (a) lateral displacement and (b) curvature angle to predict a >10% variation in stroke volume readings of the oesophageal Doppler monitor (ODM) as probe depth varies over a 10-cm range. The optimal cut-off value is shown by the open circle on the ROC curve.
