The comprehensive information on vessel anatomy and hemodynamics presented by 4D Flow MRI can be difficult to visualize. We introduce a new viewing mode using a ‘slice tool’. The use of this display algorithm can provide benefits for scalar visualization by preserving spatial location and avoiding ambiguities in cases of overlapping vessels. This novel approach can thus offer an improved understanding of complex hemodynamics within the body when used in conjunction with previously existing visualization methods eg. MIP images, pathline, and streamline visualizations.
