Figure 2 (a) Coronal-sagittal oblique scout image aligned with the aortic arch and descending aorta for assessment of distances between measurement points. Distance evaluation between the ascending aorta (AA) and proximal descending aorta (PDA) was performed by a series of short straight connected lines along the aortic luminal midline in the curved aortic arch, because the software did not allow for curved measurements. Distance between PDA and distal descending aorta (DDA) was assessed by a single-line measurement. Panels (b) and (c) show the corresponding TrueFISP images in transverse orientation.
