A vascular synthetic model for improved aneurysm segmentation and detection via Deep Neural Networks [PDF]

arXiv
We hereby present a full synthetic model, able to mimic the various constituents of the cerebral vascular tree: the cerebral arteries, the bifurcations and the intracranial aneurysms. By building this model, our goal was to provide a substantial dataset of brain arteries which could be used by a 3D Convolutional Neural Network (CNN) to either segment ...

Translating physiology of the arterial chemoreflex into novel therapeutic interventions targeting carotid bodies in cardiometabolic disorders

The Journal of Physiology, EarlyView.
Abstract figure legend The carotid body develops aberrant high activity in chronic heart failure, resistant hypertension, obstructive sleep apnoea (OSA) and diabetes. Hyperactivity of the carotid body leads to both high tonicity and increased sensitivity of the arterial chemoreflex with resultant sympathoexcitation.

Fenestration of the posterior cerebral artery P1-P2 junction: A case report

Radiology Case Reports
Fenestration is a rare anatomical variation in the posterior cerebral artery. To the best of our knowledge, there are few reports of fenestrations at the posterior cerebral artery P1-P2 junction.

MoSt-DSA: Modeling Motion and Structural Interactions for Direct Multi-Frame Interpolation in DSA Images [PDF]

arXiv
Artificial intelligence has become a crucial tool for medical image analysis. As an advanced cerebral angiography technique, Digital Subtraction Angiography (DSA) poses a challenge where the radiation dose to humans is proportional to the image count. By reducing images and using AI interpolation instead, the radiation can be cut significantly. However,

Ultra‐high temporal resolution 4D angiography using arterial spin labeling with subspace reconstruction

Magnetic Resonance in Medicine, Volume 93, Issue 5, Page 1924-1941, May 2025.
Abstract Purpose To achieve ultra‐high temporal resolution non‐contrast 4D angiography with improved spatiotemporal fidelity. Methods Continuous data acquisition using 3D golden‐angle sampling following an arterial spin labeling preparation allows for flexibly reconstructing 4D dynamic angiograms at arbitrary temporal resolutions. However, k‐space data

Clinical and Electrocardiographic Characteristics in NSTEMI Patients With Acute Total Occlusion of Culprit Left Circumflex Artery

Annals of Noninvasive Electrocardiology, Volume 30, Issue 3, May 2025.
The LCX is the most prevalent culprit vessel with acute complete occlusion in NSTEMI patients, yet it has little effect on clinical outcomes. This subset of patients may be predicted by STV5 + STV6 ≥ 2.5 mm and T‐wave imbalance. ABSTRACT Background Complete blockage of the culprit coronary artery is associated with 30% of NSTEMI (non‐ST‐segment ...

Automated Registration of 3D Neurovascular Territory Atlas to 2D DSA for Targeted Quantitative Angiography Analysis [PDF]

arXiv
Subarachnoid hemorrhage (SAH), typically due to intracranial aneurysms, demands precise imaging for effective treatment. Digital Subtraction Angiography (DSA), despite being the gold standard, broadly visualizes cerebral blood flow, potentially masking key details in areas.

The diagnostic value of susceptibility weighted imaging for cerebral venous malformation

Chinese Journal of Contemporary Neurology and Neurosurgery, 2010
Objective To assess the diagnostic value of susceptibility weighted imaging (SWI) for cerebral venous malformation. Methods The SWI features of 23 patients with cerebral venous malformation were analyzed retrospectively. The SWI images were compared with

Illustrator‐anatomist‐clinician triad based pedagogical model in anatomy education: An auxiliary resource amidst lack of hands‐on human dissection

Anatomical Sciences Education, Volume 18, Issue 4, Page 386-405, April 2025.
Abstract Adherence to the highest ethical standards is mandatory while handling precious human tissues received through the altruistic act of body donation. In 2019, misconduct at the Body Donation Center in Paris led to its closure. This adversely affected the hands‐on human dissection sessions within the anatomy education program at Université Paris ...
