Aortic diameter and peak velocity are important metrics
for the characterization of aortic disease. However,
these parameters are typically evaluated at selected
locations along the aorta and are thus subject to
observer variability and may miss the true maximum
aortic diameter or velocity. The purpose of this study
was to apply volumetric 4D flow MRI for the simultaneous
assessment of aorta morphometry and flow parameters
along the entire volume of the thoracic aorta in
patients with aortic dilation.
