The CT ‐Defined Hyperdense Arterial Sign as a Marker for Acute Intracerebral Large Vessel Occlusion
ConclusionsThe HAS on thin‐slice NCCT has a reasonably high sensitivity and specificity for identifying LVO in acute ischemic stroke patients presenting with an NIHSS > 10 and suspected MCA M1 or basilar artery occlusion. (Source: Journal of Neuroimaging)

Neuroimaging of Dilated Perivascular Spaces: From Benign and Pathologic Causes to Mimics
ABSTRACT
Perivascular spaces (PVSs), also known as Virchow‐Robin spaces, are pial‐lined, fluid‐filled structures found in characteristic locations throughout the brain. They can become abnormally enlarged or dilated and in rare cases can cause hydrocephalus. Dilated PVSs can pose a diagnostic dilemma for radiologists because of their varied appearance, sometimes mimicking more serious entities such as cystic neoplasms, including dysembryoplastic neuroepithelial tumor and multinodular and vacuolating neuronal tumor, or cystic infections including toxoplasmosis and neurocysticercosis. In addition, various pathologic pr...

Evaluating the Association between Enlarged Perivascular Spaces and Disease Worsening in Multiple Sclerosis
CONCLUSIONSOur preliminary findings from a relatively small study sample argue against a potential use of EPVS as early indicator of risk for disease worsening in relapsing‐remitting MS patients in a clinical setting. Although the small sample size and clinical 1.5T MRI may have limited our ability to detect a significant effect, we provided estimates of the association of EPVS with clinical and MRI indicators of disease worsening in a well‐characterized cohort of MS patients.

Decreased Signal Intensity Ratio on MRA Reflects Misery Perfusion on SPECT in Patients with Intracranial Stenosis
CONCLUSIONSIn patients with unilateral MCA stenosis, decreased SIR was correlated with misery perfusion, providing a simpler, widely available predictor of high‐risk intracranial stenosis. (Source: Journal of Neuroimaging)

Clinical and Arterial Spin Labeling Brain MRI Features of Transitional Venous Anomalies
CONCLUSIONA DVA‐like lesion with increased ASL signal likely represents a TVA with arteriovenous shunting. Our study indicates that these lesions are usually incidentally detected and have a lower risk of hemorrhage than AVMs. ASL‐MRI may be a useful tool to identify TVAs and guide further management of patients with TVAs.

Reproducibility of Brain MRI Segmentation Algorithms: Empirical Comparison of Local MAP PSTAPLE, FreeSurfer, and FSL ‐FIRST
CONCLUSIONSPSTAPLE is a useful tool for automatic human brain segmentation due to its precision and accuracy, which enable the detection of the size of the effect typically reported for neurological disorders with a substantially reduced sample size, in comparison to the other tools we assessed. This enables randomized controlled trials to be executed with reduced cost and duration, in turn, facilitating the assessment of new therapeutic interventions. (Source: Journal of Neuroimaging)
