Contrast-enhanced ultrasonography of the carotids [PDF]

open access: yesUltrasonography, 2015
Contrast-enhanced ultrasonography of the carotids has recently emerged as a complementary examination to conventional carotid Doppler ultrasonography. It is an examination providing improved visualization of the vascular lumen, more accurate and detailed

Molecular Imaging of Inflammation and Intraplaque Vasa Vasorum

open access: yes, 2013
Intraplaque neovascularization is a strong predictor of intraplaque hemorrhage and subsequent plaque rupture. Intraplaque neovascularization is caused by angiogenesis under the influence of hypoxic and inflammatory stimuli.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 20, 27 May 2026.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Relation between carotid vulnerable plaques and peripheral leukocyte: a case-control study of comparison utilizing multi-parametric contrast-enhanced ultrasound

open access: yesBMC Medical Imaging, 2019
Background This study evaluates carotid vulnerable plaques using contrast-enhanced ultrasound (CEUS) and explores the relationship between vulnerable plaques and leukocytes. Methods Sixty-two symptomatic and 54 asymptomatic patients underwent CEUS.

Cerebral Infarction: Epidemiology, Classification, Mechanisms, Diagnosis, and Management

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Within minutes after ischemia onset, deprivation of oxygen and glucose leads to rapid ATP depletion, resulting in failure of Na+/K+‐ATPase activity and membrane depolarization. This ionic imbalance promotes uncontrolled synaptic release of glutamate and excessive activation of postsynaptic NMDA and AMPA receptors.

Correlation of carotid artery atherosclerotic lesion echogenicity and severity at standard US with intraplaque neovascularization detected at contrast-enhanced US

open access: yes, 2011
To correlate echogenicity and severity of atherosclerotic carotid artery lesions at standard ultrasonography (US) with the degree of intraplaque neovascularization at contrast material-enhanced (CE ...

Novel Imaging-Based Biomarkers for Identifying Carotid Plaque Vulnerability

open access: yesBiomolecules, 2023
Carotid artery disease has traditionally been assessed based on the degree of luminal narrowing. However, this approach, which solely relies on carotid stenosis, is currently being questioned with regard to modern risk stratification approaches.

High Resolution Magnetic Resonance Vessel Wall Imaging: A Valuable Addition to Stroke Work‐Up

open access: yesEuropean Journal of Neurology, Volume 33, Issue 3, March 2026.
ABSTRACT Background Intracranial High‐Resolution Vessel Wall (HRVW) MRI is sometimes used alongside standard ischemic stroke (IS) work‐up, yet its clinical and therapeutic interests remain debated. We aimed to assess the intracranial HRVW‐MRI findings in IS patients and their impact on the IS etiologic classification as well as on treatment ...

Assessment of Carotid Plaque Stability Using Contrast-Enhanced Ultrasound and Its Correlation With the Expression of CD147 and MMP-9 in the Plaque

open access: yesFrontiers in Computational Neuroscience, 2021
This study aims to investigate the correlation between the enhancement degree of contrast-enhanced ultrasound (CEUS) and the expression of CD147 and MMP-9 in carotid atherosclerotic plaques in patients with carotid endarterectomy and evaluate the ...
