Reproducibility of Computer-Quantified Carotid Plaque Echogenicity
Background and Purpose—We sought to assess the reproducibility, interobserver variability, and application to clinical studies of a new method for the quantitative assessment of carotid plaque echogenicity. Methods—Carotid plaques were scanned with the use of ultrasound, and their images were stored in a computer. They were normalized by assigning certain gray values to blood and adventitia, an...
متن کاملComputed tomography scan based prediction of the vulnerable carotid plaque
BACKGROUND Primary to validate a commercial semi-automated computed tomography angiography (CTA) -software for vulnerable plaque detection compared to histology of carotid endarterectomy (CEA) specimens and secondary validating calcifications scores by in vivo CTA with ex vivo non-contrast enhanced computed tomography (NCCT). METHODS From January 2014 to October 2016 53 patients were included...
متن کاملCarotid artery intra-plaque attenuation variability using computed tomography
Background: In the CT assessment of the carotid plaque, the analysis of the attenuation value is a fundamental parameter in order to classify the type of the tissue that composes the plaque. The purpose of this paper is to assess the intra-plaque attenuation variability in order to verify the potential reproducibility of HU measurements. Methods: In this retrospective study, 68 consecutive pati...
متن کاملReliability of Persian Early Computed Tomography Score in Patients with Brain Infarction
Background: The one-third middle cerebral artery (1/3 MCA) method and Alberta Stroke Program Early Computed Tomography Score (ASPECTS) were used to detect significant early ischemic changes on brain computed tomography (CT) of patients with acute stroke. We designed the Persian Early CT Score (PECTS) and compared it with the above systems. Methods: The tomograms were chosen from the stroke data...
متن کاملComposition of the stable carotid plaque: insights from a multidetector computed tomography study of plaque volume.
BACKGROUND AND PURPOSE Calcification has been associated with carotid plaque stability; however, an acceptable in vivo method to define plaques based on this component remains to be developed. The purpose of our study was to compare calcified and noncalcified volumes of carotid artery culprit symptomatic plaques with asymptomatic plaques using multidetector computed tomography. METHODS We ide...
