Animal models are essential for understanding the pathology of stroke and investigating potential treatments. However, in vivo stroke models are associated, particularly in mice, with high variability in lesion volume.

Segmentation of carotid vessel wall using U-Net and segmentation average network [PDF]
Segmentation of carotid vessel wall is required in vessel wall volume (VWV) and local vessel-wall-plus-plaque thickness (VWT) quantification of the carotid artery. Manual segmentation of the vessel wall is time-consuming and prone to interobserver variability. In this paper, we proposed a convolution neural network to segment the common carotid artery (

Adjusting for bias introduced by instrumental variable estimation in the Cox Proportional Hazards Model [PDF]
Instrumental variable (IV) methods are widely used for estimating average treatment effects in the presence of unmeasured confounders. However, the capability of existing IV procedures, and most notably the two-stage residual inclusion (2SRI) procedure recommended for use in nonlinear contexts, to account for unmeasured confounders in the Cox ...

An anomalous anastomosis between the external and internal carotid arteries forming an arterial ring at the level of the cervical internal carotid artery is an extremely rare variant, and its embryological origin remains unclear.

Parallel Network with Channel Attention and Post-Processing for Carotid Arteries Vulnerable Plaque Segmentation in Ultrasound Images [PDF]
Carotid arteries vulnerable plaques are a crucial factor in the screening of atherosclerosis by ultrasound technique. However, the plaques are contaminated by various noises such as artifact, speckle noise, and manual segmentation may be time-consuming.

Unusual branching pattern of external carotid artery in the left carotid triangle [PDF]
During the routine dissection of the neck for the first MBBS students, we have found the abnormal branching of the external carotid artery in the carotid triangle.

The study reveals that microglial activation significantly contributes to neuroinflammation following cerebral ischemia‐reperfusion injury. It demonstrates that utilizing GelMA hydrogel for three‐dimensional culture of bone marrow‐derived mesenchymal stem cells (BMSCs) enhances the efficacy of BMSC‐derived exosomes in regulating microglial polarization

Atherosclerotic plaques at high risk of causing cardiovascular events are characterized by a prominent inflammatory infiltrate accompanied by the presence of an extensive network of leaky microvessels. In this paper, we present a dynamic contrast‐enhanced magnetic resonance imaging (DCE‐MRI) acquisition and compressed sensing reconstruction to aortic ...

Motion Magnification in Robotic Sonography: Enabling Pulsation-Aware Artery Segmentation [PDF]
Ultrasound (US) imaging is widely used for diagnosing and monitoring arterial diseases, mainly due to the advantages of being non-invasive, radiation-free, and real-time. In order to provide additional information to assist clinicians in diagnosis, the tubular structures are often segmented from US images.

Anomolous Origin of the Branches from the Common Carotid Artery [PDF]
The following result is found out by observing the Japanese one right internal carotid artery which is very thin and form the intero-occipital trunk. The common carotid artery are covered by the stylohyoid muscle and are divided into two branches ; the ...
