Assessment of the accuracy of MRI wall shear stress estimation using numerical simulations
Journal of Magnetic Resonance Imaging, 05/04/2012Petersson S et al.
Even in the absence of noise and for relatively simple velocity profiles, MRI wall shear stress (WSS) estimates cannot always be assumed to be linearly or even monotonically related to actual WSS. High WSS values cannot be resolved and the estimates depend on parameter setting. Nevertheless, distinguishing areas of low and moderate WSS may be feasible.
