Key result
Aortic lumen segmentation on 4D flow MRI demonstrated very good to excellent reproducibility for volume, surface area, centerline length, and maximal diameter (ICC 0.65-0.99).
Why the study?
Because segmentation variability contributes to the reproducibility of patient-specific hemodynamic properties derived from 4D flow MRI, the reproducibility and repeatability of aortic lumen segmentation needed to be assessed.
Is aortic lumen segmentation on 4D flow MRI reproducible and repeatable across examinations and observers?
Comparison

Is aortic lumen segmentation on 4D flow MRI reproducible and repeatable across examinations and observers?
Aortic lumen segmentation on 4D flow MRI demonstrates good to excellent reproducibility and repeatability for key geometric parameters.
Juffermans et al. (2020) conducted an observational in Healthy volunteers and clinical subjects (n=16). Aortic lumen segmentation on 4D flow MRI was evaluated on Interexamination, interobserver reproducibility, and intraobserver repeatability of aortic lumen segmentation. Aortic lumen segmentation on 4D flow MRI demonstrated very good to excellent reproducibility for volume, surface area, centerline length, and maximal diameter (ICC 0.65-0.99).
