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 ...

Superwide Left Atrial Circumferential Ablation for Persistent Atrial Fibrillation: A Randomized Controlled Trial

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background It remains to be answered whether further enlargement of the isolation area in the left atrium (LA) could produce better effectiveness than pulmonary vein antrum isolation (PVAI) for treatment of atrial fibrillation (AF). Aims To assess the effectiveness of superwide left atrial circumferential ablation (SWLACA) for treatment of ...

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.

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

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,

Nomogram for Deep Vein Thrombosis Prediction Post‐Endovascular Thrombectomy in Acute Ischemic Stroke: A Retrospective Multicenter Observational Study

Journal of Clinical Nursing, EarlyView.
ABSTRACT Background Deep vein thrombosis (DVT) is a frequent complication following endovascular thrombectomy (EVT) in patients with acute ischaemic stroke (AIS), potentially leading to fatal pulmonary embolism (PE). Identifying patients early at high risk for DVT is clinically important.

Real‐time ancillary diagnostics for intraoperative assessment of intestinal viability in horses–looking for answers across species

Veterinary Surgery, EarlyView.
Abstract Clinical intestinal viability assessment is associated with significant limitations, and there is an undisputable need for ancillary diagnostics during colic surgery. Human and companion animal surgeons struggle with similar intraoperative issues, yet there is little exchange between specialists.

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.
