Gender-Based Disparity in Acute Stroke Imaging Utilization and the Impact on Treatment and Outcomes: 2012 to 2021
In this study, we sought to evaluate whether a gender-based disparity exists in neuro-imaging and to determine its etiology and association with acute treatment and outcomes.

The assessment of left ventricular volume and function in gated small animal 18F-FDG PET/CT imaging: a comparative study of three commercially available software tools
ConclusionsAll three commercially available software tools are feasible in small animal cardiac volume assessment in gated18F-FDG PET/CT imaging. However, due to software-related differences in agreement analysis for cardiac volumes and function, PMOD, MIM, and QGS cannot be used interchangeably in murine research.

Comparative analysis of stenting for carotid web and atherosclerotic disease
CONCLUSION: Stenting for CaW was found to be technically simpler than CAD and not to confer increased risk of baroreceptor dysregulation. Intimal hyperplasia was uncommon in CaW cases.PMID:37563917 | DOI:10.1177/15910199231188856

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...

Prognostic value of multiphase CT angiography: estimated infarct core volume in the patients with acute ischaemic stroke after mechanical thrombectomy
To evaluate the prognostic value of multiphase computed tomography angiography (mCTA)-estimated infarct core (IC) volume in patients with acute ischaemic stroke (AIS) after mechanical thrombectomy (MT).

Performance of Automated ASPECTS Software and Value as a Computer-Aided Detection Tool ADULT BRAIN
CONCLUSIONS: Automated ASPECTS had agreement with the criterion standard similar to that of conventional ASPECTS. However, including automated ASPECTS during the evaluation of NCCT in acute stroke improved the agreement with the criterion standard and improved interrater agreement, which could, therefore, result in more uniform scoring in clinical practice.

Effect of Radiographic Contrast Media Shortage on Stroke Evaluation in the United States ADULT BRAIN
CONCLUSIONS: Our analysis reported changes in the use of CTA and CTP in patients with acute ischemic stroke during the contrast media shortage. Further research needs to identify effective strategies to reduce the reliance on contrast media–based studies such as CTA and CTP without compromising patient outcomes.

Infectious and Postinfectious Vasculopathies
Stroke is a complication of many central nervous system (CNS) infections, but only a few present with stroke without other symptoms or signs of CNS infection. Chief among these are varicella zoster virus (VZV) and syphilis. Delayed cerebral vasculopathy after successful treatment of bacterial meningitis, most commonly pneumococcal, is an emerging entity with uncertain pathogenesis.
