This study introduces a novel wall shear stress (WSS) estimation method for 4D flow MRI. The method improves the WSS accuracy by using the reconstructed pressure gradient and the flow-physics constraints to correct velocity gradient estimation. The method was tested on synthetic 4D flow data...

4D flow magnetic resonance imaging (MRI) allows for the in vivo acquisition of time-resolved three-dimensional (3D) blood flow, enabling the evaluation of hemodynamic quantities for cerebral aneurysms (CAs). However, the accuracy of flow-derived hemodynamic quantities such as pressure and wall shear stress (WSS) is affected...

Despite its clinical importance, accurately assessing the progression and risk of rupture of cerebral aneurysms is challenging. Hemodynamic factors play an important role in aneurysm progression, but previous studies have reported contradictory findings, preventing specific mechanisms from being defined. To date, the vast majority of studies...
