CT versus MR Techniques in the Detection of Cervical Artery Dissection
CONCLUSIONSCT/CTA is a reliable and better available alternative to MRI/MRA for diagnosis of sCAD. CT/CTA should be used to complement MRI/MRA in cases where MRI/MRA suggests occlusion. (Source: Journal of Neuroimaging)

Spectral Signal Density of Carotid Plaque Using Dual ‐Energy Computed Tomography
CONCLUSIONSIn the present pilot investigation, virtual monochromatic imaging at low‐energy levels derived from dual‐energy CTA allowed the largest differences in attenuation levels between tissues, without affecting vessel or plaque geometry. (Source: Journal of Neuroimaging)

Contrast Extravasation versus Hemorrhage after Thrombectomy in Patients with Acute Stroke
CONCLUSIONMRI done within 48 hours postprocedure can lead to false positive hemorrhage or false negative contrast extravasation interpretations in stroke patients possibly due to effects from the administered angiographic contrast. Additionally, MRI should be done both after 72 hours for confirmation and without gadolinium contrast as the effects of the gadolinium contrast and residual angiographic contrast could lead to misdiagnosis.

Resolution of Occlusive Carotid Artery Thrombus Treated with Anticoagulation as Demonstrated on Duplex Ultrasonography
CONCLUSIONDifferentiation between a stenotic plaque and occlusive thrombus can be achieved by ultrasonographic analysis of thrombus morphology, attachment site potential, and characteristics of a resolving thrombus. Systemic anticoagulation can safely and effectively eliminate the risk for future embolization and complete occlusion of the carotid artery in patients who present with transient ischemic events or completed infarcts of small size.

The Impact of CT Perfusion Threshold on Predicted Viable and Nonviable Tissue Volumes in Acute Ischemic Stroke
CONCLUSIONTwo commonly used tissue definitions generated significantly different lesion volumes and mismatch ratios. Threshold selection may have significant impact on patient selection for trials or reperfusion therapies. (Source: Journal of Neuroimaging)

Cerebral Gray Matter Atrophy Is Associated with the CSF IgG index in African American with Multiple Sclerosis
CONCLUSIONSAA patients with MS have lower GM volume and a stronger inverse correlation between GM volume and CSF IgG index, compared to the whites. These findings suggest a potentially prominent role of humoral immunity in mediating tissue injury in AA patients with MS. (Source: Journal of Neuroimaging)

Leptomeningeal Enhancement at 7T in Multiple Sclerosis: Frequency, Morphology, and Relationship to Cortical Volume
CONCLUSIONSLeptomeningeal enhancement on postcontrast 7T MPFLAIR is more prevalent than prior reports at 3T—occurring at frequencies closer to histopathologic data. Spread/fill foci are associated with reduced cortical gray matter volumes and may represent blood‐meningeal barrier breakdown near sites of meningeal inflammation, whereas nodular foci may be a normal variant.

Contrast ‐Enhanced Ultrasound and Elastography Imaging of the Neonatal Brain: A Review
ABSTRACT
Neonates presenting with neurologic symptoms require rapid, noninvasive imaging with high spatial resolution and tissue contrast. Magnetic resonance imaging (MRI) is currently the most sensitive and specific imaging modality for evaluation of neurological pathology. This modality does come with several challenges in the neonatal population, namely, the need to transport a possibly critically sick neonate to the MRI suite and the necessity of the neonate to remain still for a significant length of time, occasionally requiring sedation. Cranial ultrasound has provided radiologists and clinicians with an invaluable i...
