PURPOSE To develop a high isotropic-resolution sequence to evaluate intracranial vessels at 3.0 Tesla (T). MATERIALS AND METHODS Thirteen healthy volunteers and 4 patients with intracranial stenosis were imaged at 3.0T using 0.5-mm isotropic-resolution three-dimensional (3D) Volumetric ISotropic TSE Acquisition (VISTA; TSE, turbo spin echo), with(More)
BACKGROUND AND PURPOSE Ulceration in carotid plaque is a risk indicator for ischemic stroke. Our aim was to compare plaque ulcer detection by standard TOF and CE-MRA techniques and to identify factors that influence its detection. MATERIALS AND METHODS Carotid MR imaging scans were acquired on 2066 participants in the ARIC study. We studied the 600(More)
BACKGROUND AND PURPOSE MRA is widely used to measure carotid narrowing. Standard CE- and TOF-MRA techniques use highly T1-weighted gradient-echo sequences that can detect T1 short blood products, so they have the potential to identify IPH, an indicator of plaque rupture. We sought to determine the accuracy and reliability of these MRA sequences to detect(More)
BACKGROUND AND PURPOSE Pathologic studies suggest that neovascularization and hemorrhage are important features of plaque vulnerability for disruption. Our aim was to determine the associations of these features in carotid plaques with previous cerebrovascular ischemic events by using high-resolution CE-MRI. MATERIALS AND METHODS Forty-seven patients (36(More)
Late gadolinium enhancement (LGE) cardiac magnetic resonance (MR) imaging sequence is increasingly used in the evaluation of pediatric cardiovascular disorders, and although LGE might be a normal feature at the sites of previous surgeries, it is pathologically seen as a result of extracellular space expansion, either from acute cell damage or chronic(More)
Methods Five patients (4 male, age range 33-55 years) with proven spontaneous CAD were scanned at baseline (within 2 weeks of symptom initiation) and at follow-up using high resolution MRI. Axial two dimensional ECG gated double inversion recovery T1 weighted (T1W) turbo spin echo images were acquired before and after administration of 0.1 mmol/kg(More)
PURPOSE To investigate the impact of T2 relaxation of the carotid wall on measurements of its thickness. MATERIALS AND METHODS The common carotid artery wall was imaged using a spin echo sequence acquired at four echo times (17 ms to 68 ms) in 65 participants as part of VALIDATE study. Images were acquired transverse to the artery 1.5 cm proximal to the(More)
