- MRI Findings in Children with Acute Flaccid Paralysis and Cranial Nerve Dysfunction Occurring during the 2014 Enterovirus D68 Outbreak
MRI findings in 11 patients with acute flaccid paralysis are described and most commonly included extensive spinal cord lesions affecting the gray matter, especially the anterior horns, ventral cauda equina, and cervical ventral nerve roots as well as the pontinetegmentum.

- Do FLAIR Vascular Hyperintensities beyond the DWI Lesion Represent the Ischemic Penumbra?
FLAIR images from over 140 patients with acute MCA infarctions were analyzed and compared with images used to estimate the ischemic penumbra. A FLAIR-DWI mismatch was seen in 72% of patients and the authors concluded that this may be used to identify the ischemic penumbra.
- Assessment of Intracranial Collaterals on CT Angiography in Anterior Circulation Acute Ischemic Stroke
Different methods of assessing collateral circulation based on CTA were compared in 200 patients with stroke. Only the Miteff scoring system was reliable for predicting favorable outcome in these patients but poor outcomes were predictedby othermethods, too (Maas, Tan, and ASPECTS).

- Visual Outcomes with Flow-Diverter Stents Covering the Ophthalmic Artery for Treatment of Internal Carotid Artery Aneurysms
Outcomes in 28 patients in whom a stent covered the origin of the ophthalmic artery were reviewed. In 86%, the artery remained patent but 40% showed clinical ophthalmic complications. Thus, a stent covering the origin of this artery is not without complications and should be avoided when possible.
- Efficacy of Skull Plain Films in Follow-up Evaluation of Cerebral Aneurysms Treated with Detachable Coils: Quantitative Assessment of Coil Mass
Coil mass appearances were compared between initial postembolization and follow-up skull radiographs. Changes in the largest diameter of the coil mass generally indicated aneurysm recurrence, especially in the patients with high packing attenuation. Thus, lateral radiographs have the potential to predict aneurysm recurrences.

- Imaging Evidence and Recommendations for Traumatic Brain Injury: Advanced Neuro- and Neurovascular Imaging Techniques
Beyond the initial noncontrast CT, patients with brain trauma may be subjected to a variety of imaging studies. Here, the working group from the ACR Head Injury Institute discusses the use of these advanced imaging methods.
