4D flow cardiovascular magnetic resonance consensus statement
TLDR
It is described that 4D Flow CMR can be clinically advantageous because placement of a single acquisition volume is straightforward and enables flow through any plane across it to be calculated retrospectively and with good accuracy. Expand
Multicoil Dixon chemical species separation with an iterative least‐squares estimation method
TLDR
This work describes a new approach to multipoint Dixon fat–water separation that is amenable to pulse sequences that require short echo time increments, such as steady‐state free precession (SSFP) and fast spin‐echo (FSE) imaging, and extends to multicoil reconstruction with minimal additional complexity.

Comprehensive 4D velocity mapping of the heart and great vessels by cardiovascular magnetic resonance
TLDR
Multidirectional, 3D cine velocity acquisitions are contributing to the understanding of normal and pathologically altered blood flow features, and offers the potential for retrospective quantification of flow and other hemodynamic parameters. Expand
MRI-Based CFD Analysis of Flow in a Human Left Ventricle: Methodology and Application to a Healthy Heart
TLDR
A three-dimensional computational fluid dynamics (CFD) method has been developed to simulate the flow in a pumping left ventricle and results show that during diastole, blood flow through the mitral valve forms an asymmetric jet, leading to an asymmetry development of the initial vortex ring. Expand
Bicuspid Aortic Valve Is Associated With Altered Wall Shear Stress in the Ascending Aorta
TLDR
The results of this study demonstrate that bic Suspid valves induced significantly altered ascending aorta hemodynamics compared with age- and size-matched controls with tricuspid valves. Expand
Quantitative 2D and 3D phase contrast MRI: Optimized analysis of blood flow and vessel wall parameters
TLDR
Initial results in a patient with atherosclerosis suggest the potential of the CINE phase contrast (PC)‐MRI quantification method for understanding the formation and progression of cardiovascular diseases. Expand
Bicuspid Aortic Cusp Fusion Morphology Alters Aortic Three-Dimensional Outflow Patterns, Wall Shear Stress, and Expression of Aortopathy
TLDR
The presence and type of BAV fusion was associated with changes in regional wall shear stress distribution, systolic flow eccentricity, and expression of B AV aortopathy. Expand
Valve-Related Hemodynamics Mediate Human Bicuspid Aortopathy: Insights From Wall Shear Stress Mapping.
TLDR
Regions of increased WSS correspond with ECM dysregulation and elastic fiber degeneration in the ascending aorta of BAV patients, implicating valve-related hemodynamics as a contributing factor in the development of aortopathy. Expand
Analysis and generalized correction of the effect of spatial gradient field distortions in diffusion‐weighted imaging
TLDR
This study shows that the potential errors in diffusion imaging are considerable, and it is shown that retrospective corrections can be applied to reduce these errors. Expand
In Vivo Wall Shear Stress Distribution in the Carotid Artery: Effect of Bifurcation Geometry, Internal Carotid Artery Stenosis, and Recanalization Therapy
TLDR
Flow-sensitive 4D MRI identified alterations in the segmental in vivo WSS distribution associated with atherosclerotic disease, surgical therapy, and individual bifurcation geometry and could be a valuable technique to assess the individual risk of flow-mediated atherosclerosis and carotid plaque progression.
