4D flow MRI with six-directional flow encoding has enabled the assessment of turbulent flows, including mapping of incoherent flow variance. Using such, non-invasive estimation of turbulence-driven pressure drops can be computed. Here, we present an extension of the virtual-Work-Energy-Relative-Pressure method8 for the assessment of turbulence-driven pressure drops. Using the concept of virtual fields, the method accurately assesses pressure drops over a range of stenotic valve phantoms, being validated against catheter-based measurements. With virtual probing enabling the assessment of pressure drops through complex, narrow vasculatures, the incorporation of turbulence enhances the utility of the method, enabling for refined clinical hemodynamic analysis.
