Illustration of 3D-T1-BB-VISTA sequence and measurement of aortic wall geometry (32-year-old female participant). Left illustration of sagittal and transversal (reconstructed) images of the descending thoracic aorta acquired using the 3D-T1-BB-VISTA sequence. Right illustrations of quantification methods of aortic wall area and wall thickness. a, b A schematic and in vivo example of tracing of the luminal and outer contours, as well as an aortic wall thickness measurement. c A graphic illustration of the method of quantification of aortic wall area and wall thickness. Each zone between two blue lines embodies an aortic wall section. In each section, 25 thickness measurements are performed, generating in total 100 thickness measurements per image
