The diagnosis of intracranial artery stenosis in patients with stroke by transcranial Doppler ultrasound: A meta-analysis
CONCLUSION: Doppler ultrasound has good consistency with conventional methods for the diagnosis of intracranial artery stenosis in patients with a history of stroke. Different reference standards may affect sensitivity and specificity; when CTA was used as the reference standard, the consistency of the TCD in the diagnosis of intracranial artery stenosis in stroke patients was relatively good.PMID:37661896 | DOI:10.3233/THC-220844

CA-UNet Segmentation Makes a Good Ischemic Stroke Risk Prediction
AbstractStroke is still the World ’s second major factor of death, as well as the third major factor of death and disability. Ischemic stroke is a type of stroke, in which early detection and treatment are the keys to preventing ischemic strokes. However, due to the limitation of privacy protection and labeling difficulties, there are only a few studies on the intelligent automatic diagnosis of stroke or ischemic stroke, and the results are unsatisfactory. Therefore, we collect some data and propose a 3D carotid Computed Tomography Angiography (CTA) image segmentation model called CA-UNet for fully automated extraction o...

O-017 Viz LVO versus rapid LVO in detection of large vessel occlusion on computed tomography angiography for acute stroke
ConclusionViz LVO and Rapid LVO had similar NPV, but Rapid LVO produced a significantly larger number of false positive values. False positive values can be a source of alarm desensitization, leading to missed alarms or delayed responses. EF and intracranial atherosclerosis were significant predictors of incorrect predictions in both software packages. We hope this data will be used to improve future algorithms.Disclosures A.

Stroke: management and prevention
Acute stroke treatment requires clear protocols to rapidly triage patients – using appropriate investigations – for mechanical thrombectomy and intravenous thrombolysis. Computed tomography (CT) excludes haemorrhage, CT angiography locates the occluded vessel, and CT perfusion and perfusion magnetic resonance imaging identify viable tissue. An organized approach to str oke care in a specialist environment reduces disability and saves lives. Adoption of a ‘care bundle’ approach, including the active management of pyrexia and hyperglycaemia, and early screening for swallowing difficulties, is beneficial.

Slow is smooth, smooth is fast
Modern infantry combat motto. If you can’t move, you get pinned down but if you move too fast you get outflanked and surrounded. The milestone trials1 in 2015 showed that patients with large vessel occlusion can be effectively treated to prevent future disability and, to a certain extent, their mortality. Large vessel occlusion thrombectomy opened the doors of a new era in neurointerventional surgery, in which small departments, often handled by one or two operators, had to pivot and face a steady, continuous increase in the number of procedures two- or threefold their usual capacity. Stroke can also be held accounta...

White Matter Cerebrovascular Reactivity: Effects of Microangiopathy and Proximal Occlusions on the Dynamic BOLD Response
CONCLUSION: Our results suggest additive effects of microvascular and macrovascular disease upon white matter CVR, but with greater overall effects relating to macrovascular SOD than to apparent microangiopathy. Dynamic ACZ-BOLD presents a promising path towards a quantitative stroke risk imaging biomarker.BACKGROUND: Cerebral white matter (WM) microangiopathy manifests as sporadic or sometimes confluent high intensity lesions in MR imaging with T2-weighting, and bears known associations with stroke, cognitive disability, depression and other neurological disorders 1-5 . Deep white matter is particularly susceptible to isc...

Research advances in imaging markers for predicting hematoma expansion in intracerebral hemorrhage: a narrative review
ConclusionThe management of ICH presents a significant challenge, and identifying high-risk patients for HE is crucial to improving outcomes. The use of imaging markers for HE prediction can aid in the rapid identification of such patients and may serve as potential targets for anti-HE therapies in the acute phase of ICH. Therefore, further research is needed to establish the reliability and validity of these markers in identifying high-risk patients and guiding appropriate treatment decisions.
