The patient with ischemic stroke can benefit most from the earliest possible definitive diagnosis. While a quantitative evaluation of lesions on magnetic resonance images (MRIs) is effective in clinical diagnosis, manually segmenting commonly used, which is, however, tedious and time-consuming task. Therefore, how to segment fully automated manner has recently extracted extensive attentions. Considering that clinically acquired MRIs usually have thick slices, we propose 2D-slice-based...
Purpose To investigate whether patients with capsular stroke (CS) and pontine (PS) involving the motor pathway have different types of structural damage reorganization. Materials Methods With institutional review board approval after obtaining written informed consent, magnetic resonance imaging data were prospectively acquired in 115 CS, 47 PS, 116 control subjects by using four imagers from three hospitals. Patients lesions left right hemispheres analyzed (timing follow-up imaging: mean,...
This study aimed to investigate the effects of lesion side and degree motor recovery on gray matter volume (GMV) difference relative healthy controls in right-handed subcortical stroke. Structural MRI data were collected 97 patients with chronic ischemic stroke 79 controls. Voxel-wise GMV analysis was used patients. Compared controls, right-lesion demonstrated increase (P < 0.05, voxel-wise false discovery rate correction) bilateral paracentral lobule (PCL) supplementary area (SMA) right...
<h3>BACKGROUND AND PURPOSE:</h3> Intracranial atherosclerotic plaque features are potential factors associated with recurrent stroke, but previous studies only focused on a single lesion, and few investigated them perfusion impairment. This study aimed to investigate the association among whole-brain features, deficit, stroke recurrence. <h3>MATERIALS METHODS:</h3> Patients ischemic due intracranial atherosclerosis were retrospectively collected categorized into first-time recurrent-stroke...
Acute ischemic stroke (AIS) has been a common threat to human health and may lead severe outcomes without proper prompt treatment. To precisely diagnose AIS, it is of paramount importance quantitatively evaluate the AIS lesions. By adopting convolutional neural network (CNN), many automatic methods for lesion segmentation on magnetic resonance imaging (MRI) have proposed. However, most CNN-based should be trained large amount fully labeled subjects, label annotation labor-intensive...
Background Dual-energy CT (DECT) provides several novel methods to assess thrombus perviousness. We aimed evaluate whether the perviousness measured with DECT is associated improved recanalisation and better functional outcomes in acute ischaemic stroke (AIS) patients endovascular thrombectomy (EVT). Methods 108 AIS middle cerebral artery occlusion who underwent angiography on admission received EVT treatment between April 2020 September 2023 were retrospectively analysed. Thrombus...
Currently, the selection of patients with acute anterior large vessel occlusions (LVOs) for endovascular thrombectomy (EVT) is primarily based on dynamic susceptibility contrast perfusion-weighted imaging (DSC-PWI) or computed tomography (CT) perfusion imaging. This study investigated consistency between hypoperfused tissue (HPT) (time to maximum >6 s, Tmax s) volumes estimated by corrected and uncorrected multidelay pseudo-continuous arterial spin labeling (pCASL) DSC-PWI in LVOs also...
A comprehensive assessment of collateral status can yield profound insights into the ischemic mechanism in patients experiencing acute stroke. This study aims to investigate whether time-variant and tissue-level characteristics may serve as predictors for functional outcomes undergoing endovascular thrombectomy (EVT) through application machine learning (ML) algorithms, stratify postoperative neurological recovery these patients. In this retrospective study, 128 stroke characterized by...
Abstract This study combined the Latent Dirichlet Allocation topic model to explore potential topics of new energy vehicle (NEV) policies and their impacts on corporate social responsibility (CSR) enterprises. The results reveal that financial subsidies, infrastructure development, environmental protection are most popular topics. And these three have significant positive CSR enterprises, with construction having impact. Additionally, intensity impact large‐scale enterprises is more compared...
In this study, we aimed to investigate the classification of symptomatic plaques by evaluating models generated via two different approaches, a radiomics-based machine learning (ML) approach, and an end-to-end approach which utilized deep (DL) techniques with several representative model frameworks. We collected high-resolution magnetic resonance imaging (HRMRI) data from 104 patients carotid artery stenosis, who were diagnosed either (SPs) or asymptomatic (ASPs), in medical centers. 74 SPs...
Background: Atherosclerotic plaque locations in the carotid bulb increasingly have been found to be associated with patterns of ischemic lesions and progression. However, occurrence is a complex process. We aimed investigate characteristics geometric hemodynamic parameters among patients body apical plaques identify mechanism formation location. Methods: Consecutive single stenosis (50–99%) were enrolled retrospectively. Patients divided into groups based on Plaque location identified...
Early studies have indicated that the cortico-rubro-spinal tracts play important roles in motor dysfunction after stroke. However, differential involvement of rubral branches capsular and pontine stroke, their associations with impairment are still unknown. The present study recruited 144 chronic stroke patients 91 normal controls (NC) from three hospitals, including 102 cases (CS) 42 (PS). branches, bilateral corticorubral (CRT), dentatorubral (DRT), rubrospinal (RST), cortico-spinal tract...

In order solve problem splash in MAF process, force analysis MAP processing area conducted, a composite pole device was designed simulated...
<h3>BACKGROUND AND PURPOSE:</h3> Not all tandem occlusions diagnosed on traditional vascular imaging modalities, such as MRA, represent actual complete ICA occlusion. This study aimed to explore the utility of high-resolution vessel wall in identifying true and screening patients for their suitability endovascular recanalization. <h3>MATERIALS METHODS:</h3> Patients with no signal MRA were retrospectively reviewed. Two neuroradiologists independently reviewed images assess whether there...
Background: Myelin oligodendrocyte glycoprotein (MOG) antibody–associated encephalitis is a new clinical phenotype of inflammatory demyelinating diseases. Some MOG antibody–positive patients with central nervous system events present isolated seizures. However, there are gaps in the epidemiological knowledge regarding seizures adults. This study characterized features and treatment Methods: We reviewed all admitted to Tianjin Huanhu Hospital between Jan. 1st 2017 2022, screen seizures,...
Background Acute ischemic stroke (AIS) is an acute brain injury caused by sudden occlusion of a blood vessel. Endovascular therapy the most effective way to restore flow. However, despite restoration flow in some patients, their clinical prognosis often remains unsatisfactory. Albumin has shown neuroprotective effects animal models AIS. Therefore, this study aims evaluate safety, feasibility, and efficacy local arterial infusions 20% human serum albumin solution as adjuvant after...
