Identifying Cerebral Large Vessel Occlusion in Acute Ischemic Stroke by MRI Positioning Scanning
Neurol Med Chir (Tokyo). 2021 Jun 11. doi: 10.2176/nmc.oa.2021-0028. Online ahead of print.ABSTRACTVarious approaches have been tried for acute ischemic stroke (AIS) treatment to shorten the time from onset to recanalization. MRI positioning scanning (PS), which must be taken before any MRI sequences, was examined whether it can detect cerebral large vessel occlusion. A total of 68 consecutive patients with AIS who underwent MRI and were treated with intravenous recombinant tissue plasminogen activator or mechanical thrombectomy at our hospital were retrospectively included in this study. Occluded vessels were identified o...

Predictive and diagnosis models of stroke from hemodynamic signal monitoring
AbstractThis work presents a novel and promising approach to the clinical management of acute stroke. Using machine learning techniques, our research has succeeded in developing accurate diagnosis and prediction real-time models from hemodynamic data. These models are able to diagnose stroke subtype with 30 min of monitoring, to predict the exitus during the first 3 h of monitoring, and to predict the stroke recurrence in just 15 min of monitoring. Patients with difficult access to a CT scan and all patients that arrive at the stroke unit of a specialized hospital will benefit from these positive results. The results obtai...

Improving stroke patient care through parameter optimization of non-contrast brain CT
Neuroradiologists at MMUH have been concerned with inconsistencies in brain CT image quality received from the various scanners and hospitals. Our study aimed to develop an objective method of measuring low contrast detectability (LCD) in CT, identify which combination of CT acquisition parameters maximises LCD and to investigate the variation in imaging protocols for suspected acute stroke at different institutions in the regional hospital network.

Survey of Image Quality in Irish Stroke CT Protocols
Non-contrast computed tomography (NCCT) of the brain is a critical tool in the investigation of suspected acute ischaemic stroke. The recognition of subtle differences in attenuation values between normal brain parenchyma and regions of ischaemic tissue may be crucial to accurate and timely diagnosis. Radiologists at MMUH have been concerned with inconsistencies in image quality received from the various scanners and hospitals. Our study aimed to investigate the variation in imaging protocols for suspected acute stroke at different institutions in the regional hospital network using an objective measure of low contrast detectability (LCD).

Clinical and radiological aspects of bilateral temporal abnormalities: pictorial essay
Abstract The temporal lobes are vulnerable to several diseases, including infectious, immune-mediated, degenerative, vascular, metabolic, and neoplastic processes. Therefore, lesions in the temporal lobes can pose a diagnostic challenge for the radiologist. The temporal lobes are connected by structures such as the anterior commissure, corpus callosum, and hippocampal commissure. That interconnectedness favors bilateral involvement in various clinical contexts. This pictorial essay is based on a retrospective analysis of case files from a tertiary university hospital and aims to illustrate some of the conditions that simul...

Lacunar Stroke Lesion Extent and Location and White Matter Hyperintensities Evolution 1 Year Post-lacunar Stroke
Lacunar strokes are a common type of ischemic stroke. They are associated with long-term disability, but the factors affecting the dynamic of the infarcted lesion and the brain imaging features associated with them, reflective of small vessel disease (SVD) severity, are still largely unknown. We investigated whether the distribution, volume and 1-year evolution of white matter hyperintensities (WMH), one of these SVD features, relate to the extent and location of these infarcts, accounting for vascular risk factors. We used imaging and clinical data from all patients [n = 118, mean age 64.9 (SD 11.75) years old] who presen...

Vertebral artery injury due to air rifle: A case report
Ann Med Surg (Lond). 2021 Feb 5;63:102149. doi: 10.1016/j.amsu.2021.01.097. eCollection 2021 Mar.ABSTRACTINTRODUCTION: This case report presents a rare case of vertebral artery and spinal cord injury due to air rifle pellet.CASE PRESENTATION: A previously healthy 19-year-old male was shot on his left neck incidentally during recreational air rifle game. He was taken to the other hospital before being referred to our hospital.CLINICAL FINDINGS AND INVESTIGATIONS: The patient presented with total loss of motoric function on his left side of the body together with sensoric function on the contralateral side from the level of ...

Anticoagulant management by low-dose of low molecular weight heparin in patients with nonvalvular atrial fibrillation following hemorrhagic transformation and complicated with venous thrombosis: Five case reports and literature review
For patients with nonvalvular atrial fibrillation (NVAF) following hemorrhagic infarction (HI)/hemorrhage transformation (HT) and complicated with venous thrombosis, the management of anticoagulation is controversial. Our study intends to explore the safety and effectiveness of using low-dose of low molecular weight heparin (LMWH) to treat NVAF patients with HI (or HT) and complicated with venous thrombosis. Between January 2018 and January 2019, NVAF related acute ischemic stroke patients with HT/HI, hospitalized in the department of neurology or rehabilitation in our hospital, are enrolled retrospectively. Among them,...

Imaging-Based Outcome Prediction of Acute Intracerebral Hemorrhage
AbstractWe hypothesized that imaging-only-based machine learning algorithms can analyze non-enhanced CT scans of patients with acute intracerebral hemorrhage (ICH). This retrospective multicenter cohort study analyzed 520 non-enhanced CT scans and clinical data of patients with acute spontaneous ICH. Clinical outcome at hospital discharge was dichotomized into good outcome and poor outcome using different modified Rankin Scale (mRS) cut-off values. Predictive performance of a random forest machine learning approach based on filter- and texture-derived high-end image features was evaluated for differentiation of functional ...

Will MRI replace the EEG for the diagnosis of nonconvulsive status epilepticus, especially focal?
Authors: Gelisse P, Genton P, Crespel A, Lefevre PH Abstract Magnetic resonance imaging (MRI) can now be used to diagnose or to provide confirmation of focal nonconvulsive status epilepticus (NCSE). Approximately half of patients with status epilepticus (SE) have signal changes. MRI can also aid in the differential diagnosis with generalized NCSE when there is a clinical or EEG doubt, e.g. with metabolic/toxic encephalopathies or Creutzfeldt-Jakob disease. With the development of stroke centers, MRI is available 24h/24 in most hospitals. MRI has a higher spatial resolution than electroencephalography (EEG). MRI wit...

Bilateral large vessel occlusion causing massive ischemic stroke in a covid-19 patient
The case of a 70-year-old male presenting an ischemic stroke related to COVID-19 infection is described. He was initially admitted to the hospital with respiratory insufficiency syndrome secondary to pneumonia caused by SARS Co2. In the next days, he developed rapid neurological deterioration characterized by drowsiness which progressed to deep coma. D-dimer was elevated. Brain CT scan showed bilateral massive ischemic stroke located in the anterior circulation, CT angiogram showed occlusion in the left internal carotid artery and the right middle cerebral artery.
