Impaired Retinal Vasoreactivity: An Early Marker of Stroke Risk in Diabetes
ABSTRACT Diabetes is a common cause of small vessel disease leading to stroke and vascular dementia. While the function and structure of large cerebral vessels can be easily studied, the brain's microvasculature remains difficult to assess. Previous studies have demonstrated that structural changes in the retinal vessel architecture predict stroke risk, but these changes occur at late disease stages. Our goal was to examine whether retinal vascular status can predict cerebral small vessel dysfunction during early stages of diabetes. Retinal vasoreactivity and cerebral vascular function were measured in 78 subjects (19 heal...

Wallerian Degeneration Beyond the Corticospinal Tracts: Conventional and Advanced MRI Findings
This article reviews the utility of conventional and advanced MRI techniques for assessing WD, by focusing not only on the corticospinal tract but also other neural tracts less commonly thought of, including corticopontocerebellar tract, dentate‐rubro‐olivary pathway, posterior column of the spinal cord, corpus callosum, limbic circuit, and optic pathway. The basic anatomy of these neural pathways will be discussed, followed by a comprehensive review of existing literature supported by instructive clinical examples. The goal of this review is for readers to become more familiar with both conventional and advanced MRI f...

Telestroke Imaging: A Review
ABSTRACT The use of telecommunications technology to provide the healthcare services, telemedicine, has been in use since the 1860s. The use of technology has ranged from providing medical care to far‐off places during wartimes to monitoring physiological measurements of astronauts in space. Since the 1990s, reports have been published on diagnoses of neurological diseases with the use of video links. Studies confirm that the neurological examinations, including the National Institutes of Health Stroke Scale, performed during teleneurology are dependable. The transfer of stroke patients in rural hospitals to bigger medic...

The Association between Diffusion MRI ‐Defined Infarct Volume and NIHSS Score in Patients with Minor Acute Stroke
CONCLUSIONIn patients with minor stroke, the nature of deficit when used with the NIHSS score can improve prediction of infarct volume. This may have clinical and therapeutic implications. (Source: Journal of Neuroimaging)

Bilateral Hippocampal Restricted Diffusion: Same Picture Many Causes
ABSTRACT With some regularity, we have encountered the unusual imaging abnormality of bilateral hippocampal restricted diffusion, either in isolation or in combination with other coincident abnormalities. In this retrospective case series, we examine clinical and imaging data to explore potential etiologies and clinical implications of this imaging finding. Sixteen cases with the imaging abnormality are presented, with etiologies including hypoxemia, hypoxemia‐ischemia, and seizures. (Source: Journal of Neuroimaging)

Off ‐Label Uses for Flow Diversion in Intracranial Aneurysm Management
ABSTRACT Treatment of complex aneurysms using microsurgical and other conventional neuroendovascular techniques remains challenging. As a result, stent‐ and balloon‐assisted coiling are instead performed to treat morphologically complex aneurysms, which include giant, wide‐necked, and fusiform aneurysms. While these techniques have had success in treating these complex aneurysms, recanalization rates associated with these techniques are still problematic. In the constant effort to improve the outcome of complex aneurysm treatment, flow‐diverting stents (FDSs) have emerged in recent years as the preferred treatment....

Neuroimaging Findings in Pediatric Genetic Skeletal Disorders: A Review
ABSTRACT Genetic skeletal disorders (GSDs) are a heterogeneous group characterized by an intrinsic abnormality in growth and (re‐)modeling of cartilage and bone. A large subgroup of GSDs has additional involvement of other structures/organs beside the skeleton, such as the central nervous system (CNS). CNS abnormalities have an important role in long‐term prognosis of children with GSDs and should consequently not be missed. Sensitive and specific identification of CNS lesions while evaluating a child with a GSD requires a detailed knowledge of the possible associated CNS abnormalities. Here, we provide a pattern‐rec...

Quantitative Analysis of Extracranial Arterial Tortuosity in Patients with Sickle Cell Disease
CONCLUSIONSExtracranial carotid and vertebral arterial tortuosity is increased in SCD patients. This could be related to aberrations in hemodynamics from nonlaminar flow in these vessels. These increases in extracranial vascular tortuosity could potentially lead to alterations in intracranial vascular tortuosity and may be an independent risk factor for cerebral infarct.

Characteristics of Accredited Transcranial Doppler Ultrasound Laboratories in the United States
CONCLUSIONSThe results suggest that there are significant differences between IAC applicant laboratories and laboratories represented by Centers for Medicaid and Medicare Services (CMS) claims data. In addition, accurate study reporting, physician training, and ongoing quality improvement activities may not be optimized in laboratories applying for accreditation. With the information learned from this study, educational strategies by professional organizations, including the IAC, can be tailored to help improve TCD practice. (Source: Journal of Neuroimaging)

An Acute Disseminated Encephalomyelitis ‐Like Illness in the Elderly: Neuroimaging and Neuropathology Findings
CONCLUSIONEach of these patients was found to have pathological findings of acute demyelination on tissue diagnosis, suggesting ADEM or ADEM‐like disease. The initial presentation and imaging was pointing toward other diagnoses. Broad differential diagnosis is important, especially for older patients, and pathological proof might be warranted for a conclusive diagnosis. (Source: Journal of Neuroimaging)

The Effects of DWI ‐Infarct Lesion Volume on DWI‐FLAIR Mismatch: Is There a Need for Size Stratification?
CONCLUSIONThe effects of stroke onset‐to‐scan time gap on DWI‐FLAIR mismatch are not the same for different DWI lesion volumes. At DWI lesion volumes >15 mL, the DWI‐FLAIR mismatch is highly specific for acute infarcts within IV thrombolytic therapy time, and can identify wake‐up stroke patients eligible for treatment.

Population ‐Level Correction of Systematic Motion Artifacts in fMRI in Patients with Ischemic Stroke
CONCLUSIONSWe proposed a postprocessing pipeline for ischemic stroke fMRI data that combine the CompCor correction at first level with the modeling of motion effect at second‐level analysis by a parameter obtained from fMRI data. Our solution is applicable for any fMRI‐based stroke rehabilitation study since it does not require any MRI‐compatible motion capture system and is based on commonly used methods.
