Vulnerable carotid plaque imaging and histopathology without a dedicated MRI receiver coil.

Stroke is associated with vulnerable carotid artery plaques showing specific histopathologic features, namely a lipid-rich necrotic core, intraplaque hemorrhage, ulceration, and thin fibrous cap. While ultrasound and computed tomography (CT) can identify carotid plaques and determine the extent of stenosis, magnetic resonance imaging (MRI) provides further information regarding plaque composition and morphology. In this feasibility study, three patients with symptomatic, moderately stenosed plaques were imaged with CT angiography (CTA) and MRI (3T and 1.

Psychological comorbidities and compliance to interventional treatment of patients with cutaneous vascular malformations.

Purpose: The aim of this study was to assess qualitatively the psychological stressors affecting patients with cutaneous vascular malformations and hemangiomas (CVM-H) and their impact on compliance to interventional treatment.

Methods: A retrospective chart review was conducted of all patients with CVM-H treated by interventional neuroradiology at a single academic institution during a five-year period (2009-2014). Psychological complaints were documented during each clinic visit by a neuroradiologist.
