“…One study reported an association between unilateral ischemic stroke and lower mean WSS in the ipsilateral common carotid artery. 16 Likewise, low internal carotid and basilar artery WSS have been related to mild cognitive impairment and Alzheimer disease. 17 Intracranially, both lower and higher intracranial WSS were correlated with intracranial stenoses and aneurysm growth and rupture.…”

“…Still, 1 study reported a lower mean WSS in the common carotid artery ipsilateral to unilateral ischemic stroke, accompanied by more evident atherosclerotic plaques at the same side. 16 A major strength of this study is its individually modeled viscosity values as opposed to a fixed value used by other studies. 14 Another major strength of the methods used in this study are the 4-dimensional (3-dimensionalϩtime) MR measurements of WSS requiring minimal manual interference.…”

on behalf of the PROSPER Study GroupBackground and Purpose-Low wall shear stress (WSS) is an early marker in the development of vascular lesions. The present study aims to assess the relationship between diastolic and systolic WSS in the internal carotid artery and periventricular (PWML), deep white matter lesions, and cerebral infarcts (CI). Methods-Early, mid, and late diastolic and peak systolic WSS were derived from shear rate obtained by gradient echo phase contrast magnetic resonance sequences multiplied by individually modeled viscosity. PWML, deep white matter lesions, and CI were derived from proton density (PD), T2, and fluid attenuated inversion recovery (FLAIR) MRI in 329 participants (70 -82 years; PROSPER baseline

Purpose:To determine the extent of thickening of the carotid arterial walls that may be accommodated by outward remodeling. Materials and Methods:Institutional review board approval was obtained at each participating site, and informed consent was obtained from each participant. All study sites conducted this study in compliance with HIPAA requirements. A total of 2066 participants (age range, 60-85 years) from the Atherosclerosis Risk in Communities (ARIC) study were enrolled in the ARIC Carotid MRI Study. Maximum wall thickness and luminal area were measured with gadolinium-enhanced magnetic resonance (MR) imaging in both common carotid arteries (CCAs) and in one internal carotid artery (ICA) 2 mm above the fl ow divider. Complete data were available for 1064 ICAs and 3348 CCAs. The association of maximum wall thickness with lumen area was evaluated with linear regression, and adjustments were made for participant age, sex, race, height, and height squared . Results:In the ICA, lumen area was relatively constant across patients with a wall thickness of 1.38 mm or less . In patients with a wall thickness of more than 1.38 mm, however, lumen area decreased linearly as wall thickness increased. Wall area represented a median of 61.9% of the area circumscribed by the vessel at a maximum wall thickness of 1.50 mm 6 0.05 (standard deviation) and 75.4% at a maximum wall thickness of 4.0 mm 6 0.10. In the CCA, lumen area was preserved across wall thicknesses less than 2.06 mm, representing 99% of vessels. Conclusion:Atherosclerotic thickening in the ICA appears to be accommodated for vessels with a maximum wall thickness of less than 1.5 mm. Beyond this threshold, greater thickness is associated with a smaller lumen. The CCA appears to accommodate a wall thickness of less than 2.0 mm. These estimates indicate that the carotid arteries are able to compensate for a greater degree of thickening than are the coronary arteries.q RSNA, 2010

“…However, we measured such plaque borders by defining the plaque as suggested by Spence et al 3,13) . Second, WSS measurement was based only on Poiseuille's law, which is a common approximation of WSS 8,30) . However, when assuming a parabolic velocity profile, the underestimation of WSS may potentially lead to inaccuracy.…”

Aim:To investigate the relationships among carotid wall shear stress (WSS), carotid intima-media thickness (IMT), and total plaque area (TPA) using ultrasound (US) in the common carotid artery (CCA) in patients with suspected coronary artery disease (CAD). Methods: Carotid artery US was performed in 950 patients with suspected CAD, and mean IMT, TPA, and hemodynamic parameters of CCA, including peak and mean WSS, were measured. We
