Worldwide Analysis of Radiology Access and Education for Stroke Care: View From Abroad From 14 Countries
The World Health Organization reports that stroke is among the leading causes of death in noncommunicable diseases worldwide despite advances in acute stroke care [1]. Early interventions in cerebrovascular accidents can prevent mortality and minimize debilitating effects of stroke. There have been major recent advancements in stroke care to intervene more quickly and effectively. We are entering a new era of stroke imaging-based treatment for late acute ischemic stroke. Recent neurointerventional trials, such as DAWN and DEFUSE 3, have transformed the way clinicians provide acute stroke care in the United States and provi...

Decreased functional connectivity within the default-mode network in acute brainstem ischemic stroke
Conclusion The finding of decreased functional connectivity within the DMN of patients with acute brainstem stroke provides novel insight into the neural mechanisms that underlie cognitive impairment following ischemic insult to this brain region.

The Modern Clinical Neuroimager: Leading the Next Generation in Stroke
ABSTRACT The recent culmination of imaging‐endowed endovascular stroke trials has decisively proven the utility of clinically relevant neuroimaging in improving the outcome of patients with potentially debilitating neurological disorders. These large multicenter trials conducted across several continents notably utilized a variety of multimodal CT/MRI modalities to rapidly identify a favorable collateral profile that presages clinically beneficial revascularization. The modern clinical neuroimager may accelerate complex decision‐making through the rational use of a variety of imaging modalities and an active feedback l...

Radionuclide Imaging in Ischemic Stroke
Ischemic stroke is caused by interruption or significant impairment of blood supply to the brain, which leads to a cascade of metabolic and molecular alterations resulting in functional disturbance and morphologic damage. The changes in regional cerebral blood flow and regional metabolism can be assessed by radionuclide imaging, especially SPECT and PET. SPECT and PET have broadened our understanding of flow and metabolic thresholds critical for maintenance of brain function and morphology: PET was essential in the transfer of the concept of the penumbra to clinical stroke and thereby had a great impact on developing treat...

Endovascular treatment outcomes using the Stroke Triage Education, Procedure Standardization, and Technology (STEPS-T) program.
Conclusions STEPS-T improved time-to-treat in patients undergoing mechanical thrombectomy for AIS. During the observation period, clinical outcomes significantly improved. PMID: 29119876 [PubMed - as supplied by publisher]

Structural brain network measures are superior to vascular burden scores in predicting early cognitive impairment in post stroke patients with small vessel disease
ConclusionsBrain network measures, but not the SVD score, are significantly correlated with cognition in post-stroke SVD patients. Mediation analysis showed that the cerebral vascular lesions produce cognitive dysfunction by interfering with the structural brain network in SVD patients. The brain network measures may be regarded as direct and independent surrogate markers of cognitive impairment in SVD.

White matter tract disruption is associated with ipsilateral hand impairment in subacute stroke: a diffusion MRI study
ConclusionILH impairment was associated with WM disruption to a combination of ipsilateral and contralesional tracts with a pattern influenced by task-related processes, supporting the degeneracy theory. We propose to integrate ILH assessment in rehabilitation programs and treatment interventions such as neuromodulation.

First experience of international proctoring hands-on stroke course using Tegus telemedical system for overcoming education challenges during the war in Ukraine
Interv Neuroradiol. 2023 Aug 9:15910199231193912. doi: 10.1177/15910199231193912. Online ahead of print.ABSTRACTInterventional neuroradiology (INR) has not yet received official certification as a surgical subspecialty in Ukraine. Consequently, there is uncertainty surrounding the availability of a neurosurgical internship and a structured INR training program to provide neuroendovascular procedures. In recent years, mechanical thrombectomy has become the standard of care for acute ischemic stroke caused by large vessel occlusion, as supported by evidence-based guidelines. This emphasizes the need for INR specialists, whic...

Education in the Interventional Radiology Department to Sustain Improvement in Intra-Arterial Treatment Times for Acute Stroke
Endovascular therapy for acute ischemic stroke requires complex care coordination where clinical outcomes are dependent on timely intervention. For every 30-minute delay in therapy, a good patient outcome decreases by 10%. At a large, academic medical center, this time interval was greater than desirable. Purpose: The purpose of the quality improvement (QI) initiative is to decrease the presentation to intra-arterial (IA) groin puncture time for strokes. This presentation describes the educational interventions implemented for interventional radiology (IR) staff, which contributed to a decreased time interval.

Increased maximum common carotid intima-media thickness is associated with smoking and hypertension in Tochigi Prefecture residents
ConclusionWe identified current smoking and hypertension as the most significant contributing factors to increased IMT-Cmax in residents of Tochigi Prefecture, emphasizing the importance of routine blood pressure monitoring and anti-smoking education in this population.

Survey of the American Society of Neuroradiology Membership on the Use and Value of Intracranial Vessel Wall MRI ADULT BRAIN
CONCLUSIONS: More than 50% of neuroradiology groups use vessel wall MR imaging for intracranial vasculopathy characterization and differentiation, emphasizing the need for additional technical and educational support, especially as clinical vessel wall MR imaging implementation continues to grow.
