Wall shear stress (WSS) is an important parameter in the assessment of atherogenesis. Increase of arterial wall volume is believed to be associated with lower wall shear stresses. Here we measure both parameters in a group of 45 subjects using 3.0 Tesla MRI. For both diastolic and systolic WSS significant correlations between WSS and mean wall area could be calculated, suggesting that MRI WSS determination is a promising tool for studying vessel wall function.
