Analysis of AneuRisk65 data: warped logistic discrimination [PDF]

open access: yesarXiv, 2013
We analyze the AneuRisk65 curvature functions using a likelihood-based warping method for sparsely sampled curves, and combine it with logistic regression in order to discriminate subjects with aneurysms at or after the terminal bifurcation of the internal carotid artery (the most life-threatening) from subjects with no aneurysms or aneurysms along the

Label Propagation for 3D Carotid Vessel Wall Segmentation and Atherosclerosis Diagnosis [PDF]

open access: yesarXiv, 2022
Carotid vessel wall segmentation is a crucial yet challenging task in the computer-aided diagnosis of atherosclerosis. Although numerous deep learning models have achieved remarkable success in many medical image segmentation tasks, accurate segmentation of carotid vessel wall on magnetic resonance (MR) images remains challenging, due to limited ...

Metal–Organic Frameworks: Unlocking New Frontiers in Cardiovascular Diagnosis and Therapy

open access: yesAdvanced Science, EarlyView.
Metal–organic frameworks (MOFs), are composed of metal ions and bridging organic ligands, are recognized as an excellent platform for host‐gust chemistry. Its rich structural composition, modifiable sites, and multilevel pore distribution can provide delivery and release of signaling molecules, probes, and therapeutic drugs, which exhibit great medical

Low‐field MRI: Clinical promise and challenges

open access: yesJournal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023
Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

Agenesis of the right internal carotid artery associated with ipsilateral Raeder syndrome, first case report

open access: yesRadiology Case Reports, 2023
Raeder's syndrome is characterized by pain, ipsilateral oculosympathetic defect (ptosis and miosis), and ipsilateral trigeminal dysfunction. We report the first case of agenesis of the right internal carotid artery, which presented with a third-order ...

Mechanical Biomimetic Nanocomposites for Multidimensional Treatment of Arterial Thrombosis

open access: yesAdvanced Science, EarlyView.
In this study, a mechanical biomimetic nanocomposite is developed, guided by photoacoustic imaging, to achieve highly efficient and safe thrombolysis through the synergistic effects of photothermal therapy and pharmacological intervention. Most notably, the nanoparticle improves the microenvironment of arterial thrombi, marked by high shear stress and ...

Anomalous external carotid-internal carotid artery anastomosis diagnosed by computed tomography angiography: a case report

open access: yesRadiology Case Reports, 2020
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.

Risk Factors and Predictive Model for Ischemic Complications in Endovascular Treatment of Intracranial Aneurysms: Insights From a Large Patient Cohort

open access: yesAGING MEDICINE, EarlyView.
Independent risk factors for ischemic complications in endovascular treatment of intracranial aneurysms were identified using machine learning methods, and the first prediction model for ischemic complications of all intracranial aneurysms was constructed. Moreover, the model showed a stable and excellent predictive efficacy.

Fetal and Primitive Type of Circle of Willis with Unilateral Trifurcation of Internal Carotid Artery

open access: yesMedicine Science, 2014
Circle of Willis is a network of arteries in the base of the brain between the internal carotid artery and the vertebral artery to establish the collateral circulation between these two major arteries.
