Wall shear stress (WSS) quantifies the frictional force that flowing blood exerts on a vessel wall and can be estimated from MR-based flow measurements via numerical differentiation. Correct assessment of WSS remains difficult because of the limited spatial resolution, partial volume effects and the per-se unknown position of the wall. It has been shown that such WSS evaluations tend to underestimate. We investigate an alternative method to evaluate WSS using the Clauser-plot method – a graphical way to estimate the WSS in fully developed turbulent stationary flow. We briefly describe the Clauser-plot method and present experimental validation in a straight tube.
