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 کاملUltrasound Assessment of Carotid Plaque Echogenicity Response to Statin Therapy: A Systematic Review and Meta-Analysis
OBJECTIVE To evaluate in a systematic review and meta-analysis model the effect of statin therapy on carotid plaque echogenicity assessed by ultrasound. METHODS We have systematically searched electronic databases (PubMed, MEDLINE, EMBASE and Cochrane Center Register) up to April, 2015, for studies evaluating the effect of statins on plaque echogenicity. Two researchers independently determin...
متن کاملImportance of Plaque Modification before Coronary Artery Stenting
Lately, the importance of plaque modification prior to stent implantation, particularly the use of cutting and scoring balloons, has been a subject of debate. Pre-treatment or plaque modification before stent implantation is an important step to achieve the best possible result and ensure long term safety and efficacy of percutaneous coronary intervention (PCI). The rationale behind plaque modi...
متن کاملAn assessment of the vulnerability of carotid plaques: a comparative study between intraplaque neovascularization and plaque echogenicity
BACKGROUND Carotid plaque echolucency as detected by Color Doppler ultrasonography (CDUS) has been used as a potential marker of plaque vulnerability. However, contrast-enhanced ultrasound (CEUS) has recently been shown to be a valuable method to evaluate the vulnerability and neovascularization within carotid atherosclerotic plaques. The aim of this study was to compare CEUS and CDUS in the as...
متن کاملUltrasonographic character of carotid plaque and postprocedural brain embolisms in carotid artery stenting and carotid endarterectomy.
OBJECTIVE To investigate ultrasonographic character of carotid plaques, and incidences of brain embolism in carotid angioplasty and stenting (CAS) and carotid endarterectomy (CEA). MATERIALS AND METHODS CEA (22/25 symptomatic lesions) and CAS (17/20 symptomatic lesions) between 2007 and 2010. Embolic protection devices (15 occlusion and 5 filtering devices) were used during CAS. Carotid plaqu...
