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.
Multicoil Dixon chemical species separation with an iterative least‐squares estimation method
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.

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.
Bicuspid Aortic Cusp Fusion Morphology Alters Aortic Three-Dimensional Outflow Patterns, Wall Shear Stress, and Expression of Aortopathy
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.
Analysis and generalized correction of the effect of spatial gradient field distortions in diffusion‐weighted imaging
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.

Aortic Dilation in Bicuspid Aortic Valve Disease: Flow Pattern Is a Major Contributor and Differs With Valve Fusion Type
Flow abnormalities may be a major contributor to aortic dilation in BAV and Fusion type affects the severity of flow abnormalities and may allow better risk prediction and selection of patients for earlier surgical intervention.
