PURPOSE Atherosclerotic carotid plaques can be quantified in vivo by MRI. However, the accuracy in segmentation and quantification of components such as the thin fibrous cap (FC) and lipid-rich necrotic core (LRNC) remains unknown due to the lack of a submillimeter scale ground truth. METHODS A novel approach was taken by numerically simulating in vivo(More)
BACKGROUND AND PURPOSE There is a need for improved risk stratification of patients with TIA/stroke and carotid atherosclerosis. The purpose of this study was to prospectively investigate the potential of integrated (18)F-FDG PET/MDCT in identifying vulnerable carotid plaques. MATERIALS AND METHODS Fifty patients with TIA/stroke with an ipsilateral(More)
PURPOSE To investigate the natural history of carotid atherosclerosis in patients who experienced a TIA or ischemic stroke. PATIENTS AND METHODS Ninety-two TIA/stroke patients (57 men, mean age 67.7 ± 9.8 years) with ipsilateral <70% carotid stenosis underwent multisequence MRI of the plaque ipsilateral to the symptomatic side at baseline and after one(More)
BACKGROUND AND PURPOSE An important characteristic of vulnerable plaque, intraplaque hemorrhage, may predict plaque rupture. Plaque rupture can be visible on noninvasive imaging as a disruption of the plaque surface. We investigated the association between intraplaque hemorrhage and disruption of the plaque surface. MATERIALS AND METHODS We selected the(More)
Automated segmentation of plaque components in carotid artery magnetic resonance imaging (MRI) is important to enable large studies on plaque vulnerability, and for incorporating plaque composition as an imaging biomarker in clinical practice. Especially supervised classification techniques, which learn from labeled examples, have shown good performance.(More)
