Reduction of Diffusion-Weighted Imaging Contrast of Acute Ischemic Stroke at Short Diffusion Times Clinical Sciences
Conclusions— Short diffusion times result in dramatically reduced diffusion contrast of human stroke. Simulations implicate a combination of neuronal beading and axonal swelling as the key structural changes leading to the reduced apparent diffusion coefficient after stroke.

Associations of Circulating Growth Differentiation Factor-15 and ST2 Concentrations With Subclinical Vascular Brain Injury and Incident Stroke Clinical Sciences
Conclusions— Circulating GDF-15 and sST2 are associated with subclinical brain injury and cognitive impairment. Higher sST2 concentrations are also associated with incident stroke, suggesting potential links between cardiac stress biomarkers and brain injury.

Predictors of Good Outcome After Stent-Retriever Thrombectomy in Acute Basilar Artery Occlusion Brief Reports
Conclusions— This study suggested that initial infarction severity and posterior circulation Acute Stroke Prognosis Early CT Score on a pretreatment DWI are independent predictors of clinical outcome after stent-retriever thrombectomy in patients with acute basilar artery occlusion.

Cardiac MRI Has Limited Additional Yield in Cryptogenic Stroke Evaluation (P1.225)
Conclusions: The addition of cMRI to TEE in the diagnostic evaluation of CS results in 9[percnt] reclassification of CCS subtype, with only 3[percnt] reclassified as a non-CS subtype. Our results indicate the need for cost-effectiveness studies assessing the role of cMRI in determining ischemic stroke etiology.Disclosure: Dr. Liberman has nothing to disclose.

Translational MR Neuroimaging of Stroke and Recovery
AbstractMultiparametric magnetic resonance imaging (MRI) has become a critical clinical tool for diagnosing focal ischemic stroke severity, staging treatment, and predicting outcome. Imaging during the acute phase focuses on tissue viability in the stroke vicinity, while imaging during recovery requires the evaluation of distributed structural and functional connectivity. Preclinical MRI of experimental stroke models provides validation of non-invasive biomarkers in terms of cellular and molecular mechanisms, while also providing a translational platform for evaluation of prospective therapies. This brief review of transla...

Overestimation of Susceptibility Vessel Sign Brief Report
Conclusions—The overestimation ratio of SVS can predict cardiogenic embolism, with both high sensitivity and specificity, which can be helpful for the management of acute ischemic stroke patients in hyperacute stage.

Change in CSF Dynamics Responsible for ICP Elevation After Ischemic Stroke in Rats: a New Mechanism for Unexplained END?
AbstractIt has been proposed that intracranial pressure (ICP) elevation and collateral failure are responsible for unexplained early neurological deterioration (END) in stroke. The study ’s aims were to investigate whether cerebral spinal fluid (CSF) dynamics, rather than edema, are responsible for elevation of ICP after ischemic stroke. Permanent middle cerebral artery occlusion (pMCAO) was induced with an intraluminal filament. At 24 h after stroke, baseline ICP was measured an d CSF dynamics were probed via a steady-state infusion method. Diffusion-weighted imaging (DWI) and T2-weighted magnetic resonance imaging wer...

Chronic Apraxia of Speech and Broca's Area Clinical Sciences
Conclusions— Persistence of AOS after 12 months is associated with large left hemispheric stroke and strokes that involve Broca’s area or other relatively anterior areas to which it is structurally or functionally connected. Patients with such lesions may benefit from early training in the use of technologies to support speech production and communication.

Long-Term Follow-up of Incidental Intracranial Aneurysms in Patients with Acute Ischemic Stroke
Conclusions: In our study, the prevalence of incidental aneurysm among acute ischemic stroke patients was 6.1%. After 2 years of follow-up, there was no aneurysm rupture or subarachnoid hemorrhage, and the diameter and shape of aneurysms did not change except for 1 patient in whom the aneurysm disappeared.
