However, since it is likely that structural changes of the carotid artery wall were present in our hypertensive patients, the present results suggest that hypertension-induced changes in CCA structural properties probably play only a minor role in …

2000年6月1日 · Abstract—The role of the increase in the common carotid artery (CCA) intima-media wall thickness (IMT) in the atherosclerotic process is questionable. This longitudinal study examined the predictive value of CCA-IMT measured at baseline examination (at sites free of plaques) on the occurrence of atherosclerotic plaques in the extracranial ...

1996年2月1日 · To quantify the degree of thickening of the carotid artery walls, the many measures of IMT were summarized into two variables: one for the CCA and one for the ICA. The maximum wall thickness of the CCA was defined as the mean of the maximum wall thicknesses for near and far wall on both the left and right sides: (mLNW+mLFW+mRNW+mRFW)/4.

2013年6月20日 · The segmentation of the common carotid artery (CCA) wall is imperative for the determination of the intima-media thickness (IMT) on B-mode ultrasound (US) images. The IMT is considered an important indicator in the evaluation of the …

2020年12月1日 · Analyzing the motion of the common carotid artery (CCA) wall yields effective indicators for atherosclerosis. In this work, we propose a state-space model and a tracking method for estimating the time-varying CCA wall radius from a …

Abstract: Analyzing the motion of the wall of the common carotid artery (CCA) yields effective indicators for atherosclerosis. In this work, we explore the use of multitarget tracking techniques for estimating the time-varying CCA radius from an ultrasound video sequence.

Abstract: The motion of the common carotid artery (CCA) wall has been established to be useful in early diagnosis of atherosclerotic disease. However, tracking the CCA wall motion from ultrasound images remains a challenging task. In this paper, a nonlinear state-space approach has been developed to track CCA wall motion from ultrasound sequences.

Objective: Most of the algorithms for the segmentation of the common carotid artery (CCA) wall require human interaction to locate the vessel in the ultrasound image. The aim of this article is to show an accurate algorithm for the computer-based automated tracing of the CCA in longitudinal B-mode ultrasound images.

2020年1月2日 · The carotid artery wall is composed of three layers: the intima, the media, and the adventitia. The intima is the innermost layer abutting the lumen. It is thin and is covered with a lining of endothelial cells. The media is the middle layer.

2010年3月1日 · We propose a novel automatic algorithm to estimate CCA diameter and IMT in ultrasound (US) images, based on separate analysis of anterior and posterior CCA walls and able to distinguish internal (intima-intima) and external (adventitia-adventitia) diameter.
