To validate the clinical feasibility of deep learning-driven magnetic resonance angiography (DL-driven MRA) collateral map in acute ischemic stroke. We employed a 3D multitask regression and ordinal neural network, called as 3D-MROD-Net, to generate DL-driven MRA maps. Two raters graded perfusion scores both conventional maps measured grading time. They also qualitatively assessed image quality Interrater inter-method agreements for between two were analyzed, along with comparison time...
Objective The present study aims to investigate 1) the risk factors for hydrocephalus and subdural hygroma (SDG) occurring after decompressive craniectomy (DC), 2) association between type of SDG hydrocephalus. Methods We retrospectively reviewed clinical radiological features 92 patients who underwent DC procedures severe head injuries. developing post-traumatic (PTH) were analyzed. Types SDGs classified according location their relationship with was investigated. Results Ultimately, 26.09%...
Abstract Objectives This study evaluated the collateral map’s ability to predict lesion growth and penumbra after acute anterior circulation ischemic strokes. Methods was a retrospective analysis of selected data from prospectively collected database. The ratio follow-up volume baseline on diffusion-weighted imaging (DWI). time-to-maximum (Tmax)/DWI Tmax > 6 s volume. hypoperfused phase_FU (phase with lesions most approximate DWI lesion) phase_baseline map. Multiple logistic regression...
Abstract To determine the value of susceptibility-weighted imaging (SWI) for collateral estimation and predicting functional outcomes after acute ischemic stroke. identify independent predictors favorable outcomes, age, sex, risk factors, baseline National Institutes Health Stroke Scale (NIHSS) score, diffusion-weighted (DWI) lesion volume, site steno-occlusion, SWI grade, mode treatment, successful reperfusion were evaluated by multiple logistic regression analyses. A total 152 participants...
Collateral circulation is associated with the differential treatment effect of endovascular thrombectomy (EVT) in acute ischemic stroke. We aimed to verify ability collateral map predict futile EVT patients anterior
Arteriovenous fistula of the scalp is relatively rare disease. We report a traumatic arteriovenous treated with complete surgical excision and review literature regard to etiology, pathogenesis, management these unusual lesions.
To investigate the clinical feasibility of a CT collateral map compared with an MRA map, focusing on perfusion (CP) estimation and baseline lesion assessment in acute ischemic stroke (AIS).
Craniectomy is widely performed to lower the intracranial pressure in various conditions, such as traumatic brain injury, stroke, or swelling. Several complications can occur after craniectomy and cranioplasty, which significantly affect prognosis of patients surgery. We studied cranioplasty factors affecting operation.Patients who underwent at Daejeon St. Mary's Hospital from 2015 2021 were included. retrospectively reviewed their medical records images. All classified according sex, age,...
This study aimed to evaluate the image quality and dose reduction of low-dose three-dimensional (3D) rotational angiography (RA) for evaluating intracranial aneurysms.We retrospectively evaluated clinical data 3D RA datasets obtained from 146 prospectively registered patients (male:female, 46:100; median age, 58 years; range, 19-81 years). The subjective 79 examinations a conventional method 67 (5-seconds 0.10-µGy/frame) was assessed by two neurointerventionists using 3-point scale four...
Purpose: Three-dimensional (3D) measurement of intracranial aneurysms is important in planning endovascular treatment, and 3D rotational angiography (RA) effective accurate measurement. The purpose this study was to evaluate the feasibility low dose RA (5 seconds 0.10 μGy/frame) measuring an aneurysm using vitro phantom.Materials Methods: We investigated <I>in vitro</i> phantom with 10 acquisitions a conventional 0.36 low-dose μGy/frame). size neck diameters were measured...
