Abstract
BACKGROUND: Single V
PURPOSE/HYPOTHESIS: To design and develop a 4D Spiral Dual V
STUDY TYPE: Prospective.
POPULATION: The studied populations were two phantoms-a straight pipe with a stenotic narrowing and a phantom of the aortic arch which included a calcific polymeric valve-under both steady and pulsatile flows, six healthy volunteers, and eight patients with severe aortic stenosis (AS).
FIELD STRENGTH/SEQUENCE: 1.5T, Dual V
ASSESSMENT: Data from the proposed sequence were compared with data from 4D Cartesian Dual V
STATISTICAL TESTS: Steady flows were compared using relative-root-mean-squared-error (RRMSE). For in vivo flows and pulsatile in vitro flows, net flow for corresponding timepoints were compared with the Pearson correlation test (P < 0.01).
RESULTS: For steady flows, RRMSEs for Single V
DATA CONCLUSION: The Dual V
LEVEL OF EVIDENCE: 2 Technical Efficacy Stage: 1 J. Magn. Reson. Imaging 2020;52:117-128.
