Black-blood dynamic contrast-enhanced carotid artery wall MRI with SRDIR preparation
Background Inflammation plays a major role in atherosclerotic plaque progression and disruption [1]. Dynamic gadolinium contrast-enhanced (DCE) vessel wall imaging has been used to compute a set of contrast kinetic parameters that may characterize the extent of inflammation of carotid plaques [2-4]. However, previous DCE techniques are limited to a 2D bright-blood acquisition and thus the accur...
متن کاملHigh spatial and temporal resolution black-blood dynamic contrast-enhanced carotid artery wall MRI using compressed sensing
Background Dynamic gadolinium contrast-enhanced (DCE) vessel wall imaging has been used to quantitatively assess the inflammatory status of carotid plaques[1]. However, several limitations of current techniques that may potentially compromise quantitative accuracy include: a) vessel wall blurring during high-spatial-resolution imaging due to arterial pulsation; b) inadequate separation between ...
متن کاملBlack-blood dynamic contrast-enhanced coronary artery wall MRI: a potential tool for kinetic-modeling-based wall inflammation assessment
Background Dynamic gadolinium contrast-enhanced (DCE) vessel wall MRI has recently been used to compute a set of model-based contrast kinetic parameters (e.g. K and Vp) that can well characterize the extent of inflammation in carotid plaques [1,2]. However, no studies have shown its feasibility in coronary artery wall, presumably due to the technical challenges in imaging such a constantly-movi...
متن کاملHomologous HOmologous Black-Bright-blood and flexible Interleaved imaging sequence (HOBBI) for dynamic contrast-enhanced MRI of the vessel wall.
PURPOSE To present a HOmologous Black-Bright-blood and flexible Interleaved imaging (HOBBI) sequence for dynamic contrast-enhanced magnetic resonance imaging (MRI) of the vessel wall. THEORY AND METHODS A HOBBI sequence is proposed to acquire high-spatial-resolution black-blood and high-temporal-resolution bright-blood dynamic contrast-enhanced images in an interleaved fashion. Black-blood im...
متن کاملAdventitial perfusion and intraplaque hemorrhage: a dynamic contrast-enhanced MRI study in the carotid artery.
BACKGROUND AND PURPOSE Autopsy studies have suggested a relationship between intraplaque hemorrhage (IPH) and vasa vasorum, which arise primarily from the adventitia. Adventitial vasa vasorum can be characterized in the carotid arteries by estimating perfusion parameters via dynamic contrast-enhanced MRI. The purpose of this investigation was to use dynamic contrast-enhanced MRI to test in vivo...
