Prediction of Ischemic Stroke in Patients with Tissue-Defined Transient Ischemic Attack
Conclusions: Compared with the established measures, our newly created scores could predict future stroke for tissue-defined TIA more reliably.

Stroke Lesion Volumes and Outcome Are Not Different in Hemispheric Stroke Side Treated With Intravenous Thrombolysis Based on Magnetic Resonance Imaging Criteria Clinical Sciences
Conclusions— We did not find differences between RHS and left HS with regards to stroke lesions volumes or outcome after thrombolysis. Previously reported hemisphere-related differences in stroke outcome may partly results from imbalances in stroke lesion volume between RHS and left HS.

Role of Acute Lesion Topography in Initial Ischemic Stroke Severity and Long-Term Functional Outcomes Clinical Sciences
Conclusions— Acute lesion topography provides important insights into anatomic correlates of admission stroke severity and poststroke outcomes. Future models that account for infarct location in addition to diffusion-weighted magnetic resonance imaging volume may improve stroke outcome prediction and identify patients likely to benefit from aggressive acute intervention and personalized rehabilitation strategies.

Cardiac magnetic resonance imaging: a new tool to identify cardioaortic sources in ischaemic stroke
Stroke of undetermined aetiology or ‘cryptogenic’ stroke accounts for 30–40% of ischaemic strokes despite extensive diagnostic evaluation. The role and yield of cardiac imaging is controversial. Cardiac MRI (CMR) has been used for cardiac disorders, but its use in cryptogenic stroke is not well established. We reviewed the literature (randomised trials, exploratory comparative studies and case series) on the use of CMR in the diagnostic evaluation of patients with ischaemic stroke. The literature on the use of CMR in the diagnostic evaluation of ischaemic stroke is sparse. However, studies have demonstrat...

Prevention of Stroke in Patients With Silent Cerebrovascular Disease: A Scientific Statement for Healthcare Professionals From the American Heart Association/American Stroke Association AHA/ASA Scientific Statement
Two decades of epidemiological research shows that silent cerebrovascular disease is common and is associated with future risk for stroke and dementia. It is the most common incidental finding on brain scans. To summarize evidence on the diagnosis and management of silent cerebrovascular disease to prevent stroke, the Stroke Council of the American Heart Association convened a writing committee to evaluate existing evidence, to discuss clinical considerations, and to offer suggestions for future research on stroke prevention in patients with 3 cardinal manifestations of silent cerebrovascular disease: silent brain infarcts...

Prognostic Evaluation Based on Cortical Vein Score Difference in Stroke Clinical Sciences
Conclusions— The Prognostic Evaluation based on Cortical vein score difference In Stroke score, a novel measure of venous enhancement on CT angiography, accurately predicts clinical outcomes. Venous features on computed tomography angiography provide additional characterization of collateral perfusion and prognostication in acute ischemic stroke.

Population-Based Case-Control Study of White Matter Changes on Brain Imaging in Transient Ischemic Attack and Ischemic Stroke Clinical Sciences
Conclusions— In contrast to small vessel ischemic events, WMC were not independently associated with other pathogenic subtypes, suggesting that WMC are unlikely to be an independent risk factor for nonsmall vessel events.

Outcomes after Tissue Plasminogen Activator Administration under the Drip and Ship Paradigm May Differ According to the Regional Stroke Care System
The drip and ship paradigm for stroke patients enhances the rate of using intravenous tissue plasminogen activator (IVT) in community hospitals. The safety and outcomes of patients treated with IVT for acute ischemic stroke (AIS) under the drip and ship paradigm were compared with patients directly treated at a comprehensive stroke center in the Busan metropolitan area of Korea. This was a retrospective study of patients with AIS treated with IVT between January 2009 and January 2012. Information on patients' baseline characteristics, neuroimaging, symptomatic intracerebral hemorrhage (sICH), and outcome 90 days after usi...

Time to Stroke Magnetic Resonance Imaging
Conclusions: Stroke guidelines favor the use of MRI over CT only during the first 12 hours from symptom onset, yet less than one-third of stroke MRIs are actually performed within this timeframe.

Discrimination of Acute Ischemic Stroke from Nonischemic Vertigo in Patients Presenting with Only Imbalance
We examined 332 consecutive patients with an acute feeling of imbalance who showed no neurologic findings or responsible lesions on CT scan at the hyperacute phase. We examined their clinical backgrounds, physical findings, and laboratory examinations, with ischemic stroke diagnosed by later CT and/or magnetic resonance imaging (MRI). We identified 41 (12.3%) ischemic stroke patients. Atrial fibrillation (odds ratio 4.1; 95% confidence interval 1.4-11.5), white blood cell count (103/μL, 1.4; 1.2-1.6), head and/or neck pain (4.6; 2.1-10.3), first attack of imbalance feeling (3.3; 1.1-12.2), and dizziness (3.7; 1.7-8.3) wer...

Should DWI MRI be the primary screening test for stroke?
Patients presenting with focal neurological symptoms may suffer from ischemic stroke, intracerebral hemorrhage, or stroke mimics. Such patients are usually screened with a noncontrast‐enhanced computed tomography to rule out hemorrhage and to detect early signs of ischemia. However, the sensitivity of noncontrast‐enhanced computed tomography for acute stroke is far inferior to that of diffusion‐weighted magnetic resonance imaging and the latter is also very sensitive for identifying acute intracerebral hemorrhage. Most centers perform a magnetic resonance imaging stroke protocol that takes long to accomplish and may ...

Global survey of the diagnostic evaluation and management of cryptogenic ischemic stroke
ConclusionsBased on self‐selected respondents from a large number of international stroke centers, transesophageal echocardiography and prolonged (>24 h) cardiac rhythm monitoring are not routinely performed in cryptogenic stroke patients, even in high‐income countries. Antiplatelet therapy is the global standard for secondary prevention of cryptogenic stroke.

Ischemic Amnesia Brief Report
Conclusions—Amnesia as the main symptom of acute ischemic cerebral events is rare, mostly transient, and easily mistaken for TGA. Although clinical clues are often present, the threshold for performing diffusion-weighted imaging in acute amnesia should be low.
