DENSE in the tubular portion of the ascending aorta. a) Cine and DENSE images were acquired in a slice through the tubular portion of the ascending aorta at the pulmonary artery. b) The circumference of the ascending aorta at diastole was delineated (red line) and the displacement field (white arrows) was used to assess its relationship with the systolic circumference (green line). Stretch analysis was subdivided into anterior (A), right (R), posterior (P), and left (L) quadrants. c) phase of the DENSE data that correspond to displacement in the anterior-posterior direction. The blue lines illustrate the inner and outer boarder of the vessel wall.
