Mineral volume and morphology in carotid plaque specimens using high-resolution MRI and CT.
OBJECTIVE High-resolution MRI methods have been used to evaluate carotid artery atherosclerotic plaque content. The purpose of this study was to assess the performance of high-resolution MRI in evaluation of the quantity and pattern of mineral deposition in carotid endarterectomy (CEA) specimens, with quantitative micro-CT as the gold standard. METHODS AND RESULTS High-resolution MRI and CT w...
متن کاملHigh resolution 3D diffusion MRI of carotid plaque on 3T
Background Diffusion MRI (DWI and ADC) has been shown to provide excellent contrast for characterizing carotid plaque components such as necrotic lipid core and intraplaque hemorrhage ex vivo [1] and in vivo [2]. However, conventional 2D EPI-based methods have suboptimal image quality and limited spatial resolution leading to difficulties in ADC calculation, limiting the clinical utility of thi...

متن کاملAtherosclerotic carotid vulnerable plaque and subsequent stroke: a high-resolution MRI study.
BACKGROUND High-resolution contrast-enhanced magnetic resonance imaging (CEMRI) has been proven to be an effective tool for the identification of carotid atherosclerotic vulnerable plaque, such as a large lipid core and thin fibrous cap. The aim of this study was to evaluate the relationship between carotid plaque characteristics and the types of stroke in patients who had carotid artery (CA) s...
متن کاملHemorrhage in the atherosclerotic carotid plaque: a high-resolution MRI study.
BACKGROUND AND PURPOSE High-resolution, multicontrast magnetic resonance imaging (MRI) has developed into an effective tool for the identification of carotid atherosclerotic plaque components, such as necrotic core, fibrous matrix, and hemorrhage/thrombus. Factors that may lead to plaque instability are lipid content, thin fibrous cap, and intraplaque hemorrhage. Determining the age of intrapla...
