To evaluate the impact of an AI-based software trained to detect cerebral aneurysms on TOF-MRA diagnostic performance and reading times across readers with varying experience levels.
Phenox flow diverters (p64 and its smaller vessel variant p48) represent an established treatment option for intracranial aneurysms. This study evaluates the safety efficacy of new generation these devices with additional antithrombotic surface coating (HPC). Consecutive patients treated between 2020 2023 at three institutions were retrospectively reviewed aneurysm characteristics, procedural details, complications, angiographic outcomes. Sixty-one (mean age 56 years) 61 The mean size was...
Reducing gadolinium-based contrast agents to lower costs, the environmental impact of gadolinium-containing wastewater, and patient exposure is still an unresolved issue. Published methods have never been compared. The purpose this study was compare performance 2 reimplemented state-of-the-art deep learning (settings A B) a proposed method for signal extraction (setting C) synthesize artificial T1-weighted full-dose images from corresponding noncontrast low-dose images.
Background This multicenter study evaluated the safety and efficacy of coated flow diverters (cFDs) for treatment ruptured intracranial aneurysms. Methods Consecutive patients treated with different cFDs aneurysms under tirofiban at eight neurovascular centers between 2016 2023 were retrospectively analyzed. The majority loaded dual antiplatelet therapy after treatment. Aneurysm occlusion was determined using O'Kelly-Marotta (OKM) grading scale. Primary outcome measures major procedural...
The Pipeline Embolization Device is a safe and effective treatment option for intracranial aneurysms. newer generations have received structural refinements surface modification to improve deliverability, procedural safety, angiographic outcomes. This multicenter study evaluated the clinical safety efficacy of 2 surface-modified iterations, Vantage Flex with Shield Technology (PFS).
This multicenter study evaluates the safety and efficacy of coated flow diverters (cFDs) for treatment cerebral aneurysms under single antiplatelet therapy (SAPT).
As the number of neurointerventional procedures continues to increase, so does need for well-trained neurointerventionalists. The purpose this work was establish and assess a systematic 3‑step approach perform acute stroke treatment including simulator training virtual supervision by remote streaming support (RESS). Five trainees (four men, one women) who have completed answered an 11-item questionnaire (5-point Likert scale) in order evaluate step 1 (simulator). Furthermore, all supervisor...
Abstract Purpose Double-layer design carotid stents have been cast in a negative light since several investigations reported high rates of in-stent occlusions, at least the acute setting tandem occlusions. CGuard is new generation double-layered stent that was designed to prevent periinterventional embolic events. The aim this study analyze safety and efficacy emergent CAS for treatment occlusions comparison with single-layer Carotid Wallstent (CWS) system. Methods All patients who underwent...
Abstract Background Dual-layer stents have fallen into disrepute after several studies reported high rates of in-stent occlusions in acute stroke treatments. The CGuard stent is a new-generation hybrid dual-layer that has been designed to provide less thrombogenicity and prevent peri- postinterventional emboli. aim the study evaluate safety efficacy for treatment occlusion or high-grade stenosis extracranial internal carotid artery (ICA) patients with ischemic (AIS) without concomitant...
<h3>Introduction</h3> Double-layer design carotid stents have been cast in a negative light since several investigations reported high rates of in-stent occlusions, at least the acute setting tandem occlusion. CGuard is new generation hybrid double-layered stent and was designed to prevent periinterventional embolic events. Results with elective artery stenting (CAS) are promising. . Aim Study: The aim this study analyze safety for treatment occlusions comparison single-layer Carotid Wall...
<h3>Introduction</h3> AI is increasingly used in clinical practice to support radiologists when reading imaging studies. <h3>Aim of Study</h3> To evaluate the impact an, based software trained detect cerebral aneurysms on TOF-MRA diagnostic performance multiple readers with different amounts experience neuroimaging. <h3>Methods</h3> 186 MRI studies were evaluated by six (three medical students, one radiology resident, radiologist and neuroradiologist) for presence aneurysms. First, was done...
