Association between signal hyperintensity on T1-weighted MR imaging of carotid plaques and ipsilateral ischemic events.
BACKGROUND AND PURPOSE To investigate associations between cerebral ischemic events and signal hyperintensity in T1-weighted MR imaging (T1WI) of carotid plaque according to stenosis severity and to estimate persistence of T1WI signal hyperintensity. METHODS A total of 222 patients (392 atherosclerotic carotid arteries) underwent plaque imaging using 3D inversion-recovery-based T1WI (magnetiz...
متن کاملCarotid Wall Imaging with Routine Brain MRI to Facilitate Early Detection of Carotid Plaque and Intraplaque Hemorrhage
permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Previous studies have reported stroke magnetic resonance imaging (MRI) assessments that included a carotid magnetization-prepared rapid acquisition with gradient-echo (MPRAGE) sequence. The findings of these studies showed that a carotid MPRAGE-positive signal was...
متن کاملHigh-intensity signals in carotid plaques on T1-weighted magnetic resonance imaging predict coronary events in patients with coronary artery disease.
OBJECTIVES The purpose of this study was to determine whether high-intensity carotid plaques visualized by a noncontrast T1-weighted imaging technique, magnetization-prepared rapid acquisition with gradient echo (MPRAGE), predict future coronary events in patients with clinically stable coronary artery disease (CAD). BACKGROUND Coronary plaque vulnerability to rupture can be assessed by exami...
متن کاملComparison between Three T1-weighted Sequences for Detection and Area Measurement of Intraplaque Hemorrhage in Carotid Atherosclerotic Plaque Imaging at 3 Tesla
Introduction: Carotid intraplaque hemorrhage (IPH) demonstrated by in vivo 1.5T MR imaging has shown associations with recent and future cerebral ischemic events and plaque progression [1-3]. Typically, T1-weighted (T1W) sequences, black-blood fast spin-echo (FSE) and bright-blood spoiled gradient-echo (SPGR), are used for IPH imaging, since formation of methemoglobin within IPH results in shor...
متن کاملAssociation of Carotid Intraplaque Hemorrhage and Territorial Acute Infarction in Patients with Acute Neurological Symptoms Using Carotid Magnetization-Prepared Rapid Acquisition with Gradient-Echo
OBJECTIVE The purpose of our study was to assess prevalence of carotid intraplaque hemorrhage (IPH) and associations between territorial acute infarction and IPH on magnetization-prepared rapid acquisition with gradient-echo (MPRAGE) in patients with acute neurologic symptoms. METHODS 83 patients with suspected acute neurologic symptoms were evaluated with both brain diffusion weighted imagin...
