MRI of geometric and compositional features of vulnerable carotid plaque.
Noninvasive imaging of atherosclerotic disease provides a powerful opportunity to gain insight into the complex chain of events underlying atherogenesis, plaque progression, and ultimately those processes that result in atherothrombosis with accompanying clinical symptoms. MRI is particularly attractive because it is noninvasive and is capable of providing a rich array of information on vascula...
متن کاملVitamin D and Vulnerable Carotid Plaque.
BACKGROUND AND PURPOSE MR imaging-detected carotid intraplaque hemorrhage indicates vulnerable plaque with high stroke risk. Angiotensin II stimulates intraplaque hemorrhage in animal models, and the angiotensin system is highly regulated by vitamin D. Our purpose was to determine whether low vitamin D levels predict carotid intraplaque hemorrhage in humans. MATERIALS AND METHODS In this cros...
متن کاملSerial carotid MRI identifies rupture of a vulnerable plaque resulting in amaurosis fugax.
A 66-year-old man with cryptogenic ischemic stroke and multiple acute ischemic lesions in the right middle cerebral artery territory was enrolled in the CAPIAS trial (Carotid Plaque Imaging in Acute Stroke; NCT01284933). Baseline carotid MRI demonstrated a right-sided nonstenotic American Heart Association type-VI plaque with a large lipid/necrotic core and intraplaque hemorrhage (figure 1). El...
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 کاملCharacterizing vulnerable plaque features with intravascular elastography.
BACKGROUND In vivo detection of vulnerable plaques is presently limited by a lack of diagnostic tools. Intravascular ultrasound elastography is a new technique based on intravascular ultrasound and has the potential to differentiate between different plaques phenotypes. However, the predictive value of intravascular elastography to detect vulnerable plaques had not been studied. METHODS AND R...
