Co-registration of the distribution of wall shear stress and 140 complex plaques of the aorta
Previous studies provide evidence that atherosclerosis develops in vascular regions
exposed to low wall shear stress (WSS) and high oscillatory shear index (OSI). 4D flow MRI
was analyzed in 70 stroke patients with complex plaques (≥ 4 mm thickness, ulcerated or
superimposed thrombi) and in 12 young healthy volunteers. The segmental distribution of
peak systolic WSS systole and OSI was quantified in analysis planes positioned directly at
the location of 140 complex plaques found in the 70 patients. In addition, WSS systole and …
