Purpose The study aimed to develop the open-source body and organ analysis (BOA), a comprehensive computed tomography (CT) image segmentation algorithm with focus on workflow integration. Methods BOA combines 2 algorithms: composition (BCA) TotalSegmentator. BCA was trained nnU-Net framework using dataset including 300 CT examinations. CTs were manually annotated 11 semantic regions: subcutaneous tissue, muscle, bone, abdominal cavity, thoracic glands, mediastinum, pericardium, breast...
Abstract The Sparsely Annotated Region and Organ Segmentation (SAROS) dataset was created using data from Cancer Imaging Archive (TCIA) to provide a large open-access CT with high-quality annotations of body landmarks. In-house segmentation models were employed generate annotation proposals on randomly selected cases TCIA. includes 13 semantic region labels (abdominal/thoracic cavity, bones, brain, breast implant, mediastinum, muscle, parotid/submandibular/thyroid glands, pericardium, spinal...
Purpose The aim of this study is to assess the impact bridging intravenous thrombolysis (IVT), infarct core growth rate (ICGR) and their interaction on neurological outcomes in patients undergoing endovascular thrombectomy (EVT) acute ischemic stroke (AIS) with anterior large vessel occlusion (LVO). Methods Patients EVT due LVO (ICA M2 branches) between 2018 2022 a tertiary care center were included. Patient's baseline characteristics, peri-procedural factors retrospectively analyzed. ICGR...
We aimed to investigate treatment effect of endovascular thrombectomy (EVT) on the change National Institutes Health Stroke Scale (NIHSS) scores in acute ischemic stroke (AIS) patients with anterior large vessel occlusion (LVO). Predictors early neurological improvement (ENI) were assessed those successful reperfusion. Data from January 2018 December 2020 retrospectively analyzed. Anterior LVO was defined as internal carotid artery and/or M1/M2 branch middle cerebral artery. A reduction at...
Solitary fibrous tumor (SFT) of the orbit is a rare that was first described in 1994. We aimed to investigate its imaging characteristics may facilitate differential diagnosis between SFT and other types orbital tumors.
Abstract Purpose We aimed to investigate the impact of post-thrombectomy isolated subarachnoid hemorrhage (i-SAH) and other types intracranial (o-ICH) on patient’s neurological outcomes. Methods Stroke data from 2018 2022 in a tertiary care center were retrospectively analyzed. Patients with large vessel occlusion ICA M2 branch included. Post-thrombectomy hemorrhages at 24 h categorized Heidelberg Bleeding Classification. Neurological impairment patients was continuously assessed admission,...
We aimed to evaluate predictors of symptomatic intracranial hemorrhage (sICH) in acute ischemic stroke (AIS) patients following thrombectomy due anterior large vessel occlusion (LVO). Data on from January 2018 December 2020 a tertiary care centre were retrospectively analysed. sICH was defined as associated with deterioration at least four points the National Institutes Health Stroke Scale (NIHSS) score or leading death. A smoothed ridge regression model run analyse impact 15 variables their...
<h3>Introduction</h3> Subarachnoid hemorrhage is a common finding, ranging from 5.2% to 15.2% in ischemic stroke patients after mechanical thrombectomy. <h3>Aim of Study</h3> We aimed evaluate neurological outcomes patient groups without intracranial (non-ICH), with isolated subarachnoid (i-SAH) and other types (o-ICH) than i-SAH <h3>Methods</h3> Stroke data 2018 2021 tertiary care centre were retrospectively analysed. Patients anterior large vessel occlusion included. Neurological...
