We present a novel analysis of 4D flow MRI in the thoracic aorta that identifies fluid structure instabilities, which are elevated in a cohort of 117 suspected-aortopathy patients as compared to 100 healthy subjects, and which are predictive of later complications shown in a follow-up analysis for 72 patients in the cohort.
