The aim of this study was to evaluate the diagnostic impact of high-spatial resolution MRI for the reliable assessment of both carotid wall thickness and compliance in order to allow a comprehensive evaluation of carotid atherosclerosis. Therefore, both parameter were measured in the common carotid arteries (CCA) of 32 healthy volunteers and 20 patients with high-grade internal carotid artery stenosis and were compared with high-resolution ultrasound as the reference method.
