Evaluating the use of gradient echo imaging for the detection of cerebral microbleeds in acute stroke cases: A retrospective data analysis in a UK stroke unit
Imaging in stroke, allows its classification into ischaemic stroke (IS) or intracranial haemorrhagic stroke (ICH), ensuring time-sensitive treatment to be administered. Imaging can also allow detection of cerebral microbleeds (CMBs), which may further determine pharmacological intervention in acute stroke. True gradient echo (T2 ∗GRE) or susceptibility weighted imaging (SWI) have high sensitivity for the detection of CMBs. These two sequences are included in the national guidelines; however, the implementation of these guidelines can vary depending on local interpretation and scanner capabilities.

Modern Neuroimaging Techniques in Diagnosing Transient Ischemic Attack and Acute Ischemic Stroke
Neuroimaging should be obtained for all patients suspected of having acute ischemic stroke or transient ischemic attack. Noncontrast head computed tomography (CT) scans are used to exclude hemorrhage, evaluate for early brain injury, and exclude stroke mimics. CT angiography assists in identifying proximal vessel occlusions, dissection, or high-grade arterial stenoses. Additional imaging techniques have emerged to improve selection of patients likely to benefit from therapies. Artificial intelligence applications assist in acute stroke imaging assessment, identifying acute hemorrhage, and predicting risk of endovascular in...

Brain Imaging Findings and Response to Intravenous Thrombolysis in Posterior Circulation Stroke
ConclusionsEarly ischaemic signs and pre-existing structural signs should be considered during the assessment of patients with PCIS eligible for IVT. Tissue hypoattenuation on initial CT scans correlates with an increased risk of death. Similarly to anterior circulation, atrophy on initial MRI may negatively predict good clinical outcome in posterior circulation.

Preoperatively estimated graft flow rate contributes to the improvement of hemodynamics in revascularization for Moyamoya disease
Moyamoya disease is a cerebrovascular disease that is characterized by chronic progressive stenosis of the terminal portion of the internal carotid artery (ICA) on both sides of the brain, which results in an abnormal vascular network of the collateral pathways at the base of the brain.1,2 Therefore, patients with Moyamoya disease have a decreased cerebral blood flow (CBF) and reduced cerebral perfusion pressure,3 which can result in ischemic and/or hemorrhagic stroke. This hemodynamic condition can be evaluated using positron emission tomography (PET) or single-photon emission computed tomography (SPECT) as the gold standard procedure.

Reductions in Hospital Admissions and Delays in Acute Stroke Care During the Pandemic of COVID-19
Conclusions: Profound reductions in stroke hospital admissions and significant delays in emergency care for acute ischemic stroke occurred during the pandemic of COVID-19. Engagement and effective communication with all stakeholders including patients, health care providers, governmental policymakers, and other implementation partners are required for future success in similar crises.

Assessment of Patients with Intracerebral Hemorrhage or Hemorrhagic Transformation in the VENOST Study
Conclusion: CVST, an important cause of stroke in the young, should be monitored closely if the patients have additional symptoms of headache, multiple sinus involvement, and CH. Older age and parenchymal lesion, either hemorrhagic infarction or intracerebral hemorrhage, imply poor outcome.Eur Neurol

Accuracy and Implications of Hemorrhagic Stroke Recognition by Emergency Medical Services.
CONCLUSIONS: Among EMS-transported hemorrhagic stroke cases, stroke screen documentation was strongly associated with EMS stroke recognition, which was in turn associated with higher quality of EMS care and faster CT scans upon emergency department arrival.

3D Deep Neural Network Segmentation of Intracerebral Hemorrhage: Development and Validation for Clinical Trials
AbstractIntracranial hemorrhage (ICH) occurs when a blood vessel ruptures in the brain. This leads to significant morbidity and mortality, the likelihood of which is predicated on the size of the bleeding event. X-ray computed tomography (CT) scans allow clinicians and researchers to qualitatively and quantitatively diagnose hemorrhagic stroke, guide interventions and determine inclusion criteria of patients in clinical trials. There is no currently available open source, validated tool to quickly segment hemorrhage. Using an automated pipeline and 2D and 3D deep neural networks, we show that we can quickly and accurately ...

Rules About Rules – The 6-h CT Rule For Subarachnoid Hemorrhage
In this issue of the Journal of Stroke and Cerebrovascular Diseases, Chakraborty and colleagues describe the cautionary tale of a patient who presented with a thunderclap headache concerning for a subarachnoid hemorrhage (SAH). A head computed tomographic scan (CT) done 4  h after the onset of the headache was interpreted as negative but the patient was ultimately found to have an aneurysmal SAH.1

Dabigatran Reversal with Idarucizumab Preceding Thrombolysis in an Octogenarian Patient with Chronic Kidney Disease and Acute Stroke: a Case Report.
CONCLUSION: Our case showed the effectiveness and safety of giving Idarucizumab followed by thrombolysis in Dabigatran-treated atrial fibrillation with ischemic stroke. Based on this case, the procedure can be performed in an elderly population with chronic kidney disease when administered close to the limit of threshold for thrombolysis.

CT Scanning in Suspected Stroke or Head Trauma: Is it Worth Going the Extra Mile and Including the Chest to Screen for COVID-19 Infection? ADULT BRAIN
CONCLUSIONS: The sensitivity of additional chest CT is fairly high. However, a negative result does not exclude COVID-19. The positive predictive value is poor. Correlation of chest CT results with epidemiologic history and clinical presentation, along with real-time reverse transcriptase polymerase chain reaction, is needed for confirmation.
