Endovascular therapy for acute ischemic stroke is generally avoided when the infarction large, but effect of endovascular with medical care as compared alone large strokes has not been well studied.
Endovascular therapy (EVT) has been found to reduce functional disability in patients with acute stroke due large-vessel occlusion. However, the extent of ischemic region, measured using Alberta Stroke Program Early Computed Tomography Scores, may limit efficacy EVT.To compare and safety EVT according ASPECTS 3 or less vs 4 5.The Recovery by Salvage for Cerebral Ultra-acute Embolism-Japan Large Ischemic Core Trial (RESCUE-Japan LIMIT) was an open-label randomized clinical trial conducted...
Abstract This retrospective study aimed to develop and validate a deep learning model for the classification of coronavirus disease-2019 (COVID-19) pneumonia, non-COVID-19 healthy using chest X-ray (CXR) images. One private two public datasets CXR images were included. The dataset included from six hospitals. A total 14,258 11,253 in 2 455 dataset. based on EfficientNet with noisy student was constructed three datasets. test set 150 evaluated by radiologists. Three-category accuracy...
The increased risk of intracranial hemorrhage with multiple passes in endovascular therapy (EVT) for large vessel occlusion a ischemic core is concern. We explored the effect number EVT on patients randomized clinical trial.This post hoc study was secondary analysis RESCUE-Japan LIMIT, which trial comparing and medical treatment alone core. grouped according to successful reperfusion (modified Thrombolysis Cerebral Infarction score, ≥2b) 1, 2, 3 7 failed 0-2a) after any pass group, these...
BACKGROUND: We aimed to examine the boundary of ischemic core volume in patients undergoing endovascular thrombectomy (EVT) versus those receiving medical management determine minimum optimal size for favorable treatment outcomes. METHODS: This is a prespecified substudy RESCUE-Japan LIMIT (Recovery by Endovascular Salvage Cerebral Ultra-Acute Embolism-Japan Large Ischemic Core Trial). Patients with large vessel occlusion were enrolled between November 2018 and September 2021 National...
Purpose: We explored appropriate scan timing for bone marrow imaging enhanced using superparamagnetic iron oxide (SPIO) and evaluated the usefulness of SPIO in differentiating metastasis osteomyelitis patients. Methods: To determine adequate after administration SPIO, 5 healthy subjects were examined a 1.5T magnetic resonance (MR) scanner. Sagittal images their lumbar spines obtained short-TI inversion recovery (STIR) sequence before 3, 6, 9, 24, 48 hours intravenous injection 8 μmol Fe/kg...
The principles of echo-shifting with a train observations (PRESTO) magnetic resonance (MR) imaging technique employs an MR sequence that sensitively detects susceptibility changes in the brain. effectiveness PRESTO was examined for distinguishing between cerebellopontine angle (CPA) schwannomas and meningiomas 24 patients CPA tumors, 12 vestibular schwannomas, meningiomas. Histopathological study surgical specimens showed 11 contained hemosiderin deposits all had microhemorrhages. One...
We sought to develop a surgical navigation system using magnetic resonance angiography (MRA) and three-dimensional (3D) printer for robot-assisted radical prostatectomy (RARP). Six patients with pathologically proven localized prostate cancer were prospectively enrolled in this study. Prostate imaging (MRI), consisting of T2-weighted sampling perfection application-optimized contrasts different flip-angle evolutions (SPACE) true fast steady-state precession (true FISP), reconstructed by...
Endovascular therapy is strongly recommended for acute cerebral large vessel occlusion (LVO) with an Alberta stroke program early computed tomography score (ASPECTS) ≥6 due to of the internal carotid artery or M1 segment middle artery. However, effect endovascular patients a ischemic core ASPECTS ≤5 (0-5) was not established. A multicenter, randomized, open-label, parallel-group trial conducted investigate superiority over medical without (3-5). Patients were randomly assigned receive at...
Objectives/Hypothesis The purpose of this study was to estimate the efficacy superselective arterial chemoradiotherapy for locally advanced carcinomas external auditory canal and middle ear. Study Design A retrospective clinical data consecutive patients with Methods Thirteen ear (T3: one patient, T4: 12 patients) were reviewed. median follow-up duration in living 33 months. total dose radiation therapy 60 Gy using conventional fractionation. Four, five, or six courses a infusion (cisplatin...
Abstract To evaluate the diagnostic performance of our deep learning (DL) model COVID-19 and investigate whether radiologists was improved by referring to model. Our datasets contained chest X-rays (CXRs) for following three categories: normal (NORMAL), non-COVID-19 pneumonia (PNEUMONIA), (COVID). We used two public private dataset collected from eight hospitals development external validation DL (26,393 CXRs). Eight performed reading sessions: one session with reference CXRs only, other...
Background The efficacy of endovascular therapy (EVT) in patients with large ischemic core has been reported, but it remains unclear whether IV alteplase (IVT) beneficial effects addition to EVT such patients. We evaluated the and safety or without IVT. Methods RESCUE-Japan LIMIT was an open-label, prospective, multicenter, randomized clinical trial evaluate stroke core, defined as Alberta Stroke Program Early CT Score (ASPECTS) 3–5. This subanalysis differences medical care (EVT group)...
We report a case of central neurocytoma that manifested tumor recurrence with craniospinal dissemination. Imaging studies before surgery showed markedly enhanced small cysts and calcification, which invaded the adjacent brain parenchyma, located in posterior horn right lateral ventricle. Proton MR spectroscopy elevated choline lactate peaks strongly diminished N-acetylaspartate peak. Two years after neurosurgical intervention, multiple dissemination middle cranial fossa intradural...
Automated stripping of skulls from infantile brain MR images is the fundamental work to visualize cerebral surface and measure volumes. They are important evaluate diseases because most cause morphometric changes in cerebrum. This study proposes a novel image segmentation method based on fuzzy rule-based active model. The proposed was validated by applying it two neonatal (3W 4W) six (5W 4Y2M) subjects. mean sensitivity 98.84 %, false-positive rate 1.21 visualized well.
Abstract Background This study aimed to assess the effectiveness and versatility of an intentional early detachment technique with detachable coils in addressing challenging vascular embolization scenarios. novel approach aims provide alternative method for achieving precise coil placement when standard methods are ineffective owing anatomy or limited available equipment. Materials retrospective included 11 patients (nine males two females; median age, 77 years) who underwent procedures...
