CMR measuring positions, where pos1, pos3 and pos 6 were also measured by echocardiography. Post-processing of 3D isotropic CMR in positon 1 of the ascending aorta, at sinotubular level. It illustrates the ability to ensure precise and reproducible measurement of aortic diameter, where accuracy is ensured by the use of 3 separate planes placed perpendicular to each other and the aortic wall at the position of measuremtn.
