2019年11月4日 · Intracranial anterior circulation LVOs and proximal M2 occlusions can be rapidly and reliably detected by an automated detection tool, which may facilitate intra- and inter-instutional workflows and emergent imaging triage in the care of patients with stroke.

2020年9月29日 · Large vessel occlusion (LVO) stroke is one of the most time-sensitive diagnoses in medicine and requires emergent endovascular therapy to reduce morbidity and mortality. Leveraging recent advances in deep learning may facilitate …

Five hundred twenty consecutive patients with a clinical diagnosis of acute ischemic stroke (49% men; mean age, 72 years; range, 19–100 years) who underwent CTA to evaluate LVO of the proximal anterior circulation at Zuyderland Medical Center between January 2019 and August 2019 were included.

2023年5月31日 · In this study, a state-of-the-art self-configuring object detection network called nnDetection was used to detect LVO and assess collateralization on CTA scans using a multi-task 3D object...

CT血管造影（CT Angiography，CTA）可以用于筛选患者是否存在LVO，将阳性发现提供给神经放射介入医生或卒中中心，促进卒中中心和神经放射介入团队的快速行动；也有助于基层医院全天候、可靠地识别LVO；帮助卒中中心优化工作流程和人员配备，调动抢救力量。

2025年3月10日 · To validate JLK-LVO, a software detecting large vessel occlusion (LVO) on computed tomography angiography (CTA), within a multicenter dataset. From 2021 to 2023, we enrolled patients with ischemic stroke who underwent CTA within 24-hour of onset at six university hospitals for validation and calibration datasets and at another university hospital for an independent dataset for testing model ...

2025年3月1日 · CT recorded an acute aorto-mitral angle, shorter SLCL, smaller end-systolic LV and smaller LVOT areas in patients with LVO. Regression analysis identified predictors of LVO the end-systolic LV area and the anatomical SLCL.

Early diagnosis of large vessel occlusion (LVO) in acute stroke often requires CT angiography (CTA). Automated CT perfusion (CTP) software, which identifies blood flow abnormalities, enhances LVO diagnosis and patient selection for endovascular ...

Identifying large vessel occlusion (LVO) is of significant importance for the treatment and prognosis of acute ischemic stroke (AIS) patients. CT Angiography (CTA) is commonly used in LVO identification due to its visibility of vessels and short acquisition time.

2023年8月2日 · The aim of this study was to evaluate the diagnostic performance of the AP for the detection of intracranial large vessel occlusions (LVO) on conventional CT angiography (CTA), and the duration...
