22 Assessing altered aortic haemodynamics in patients with bicuspid aortic valves: a novel volumetric quantification of vorticity using 4D Flow

Abstract

and 3T (T2 global 40.0 ± 2.4 msec vs 39 ± 2 msec, p = 0.864 and T2 mid septal 42.3 ± 3.8 msec vs 41 ± 2 msec, p = 0.447). Conclusion This study confirms that T1 and T2 mapping times were not significantly different following recent scanner upgrades within the same institution both through segmental and global analyses. The collection of data on local standard deviation has also facilitated the introduction of Z-scores to clinical reports to aid interpretation of mapping data across multiple field strengths.
