Overall reproducibility in identifying the fibrous cap of carotid artery plaques by non contrast-enhanced (CE-) MRI has shown to be poor. CE-MRI is capable of quantitatively measuring the dimensions of the intact fibrous cap. This study found good inter- and intraobserver agreement in assessing fibrous cap status on a per-plaque basis by using CE-MRI. Future prospective longitudinal studies can rely on CE-MRI to assess the predictive value of fibrous cap status of carotid artery plaques on the occurrence of cerebral ischemic events.
