- Hyperintense Vessels on FLAIR: Hemodynamic Correlates and Response to Thrombolysis
The authors evaluated 62 consecutive patients with ischemic stroke with proven vessel occlusion with MRI before and within 24 hours of treatment and defined a hypoperfusion intensity ratio (volume with severe/mild hypoperfusion [time-to-maximum ≥ 8 seconds / time-to-maximum ≥ 2 seconds]). Patients with extensive hyperintense vessels on FLAIR (>4 sections) had higher NIHSS scores, larger baseline lesion volumes, higher rates of perfusion-diffusion mismatch, and more severe hypoperfusion intensity ratio.
- Improving Multiple Sclerosis Plaque Detection Using a Semiautomated Assistive Approach
The authors evaluated and validated a semiautomated software platform to facilitate detection of new lesions and improved MS lesions. Two neuroradiologists retrospectively assessed 161 MR imaging comparison study pairs acquired between 2009 and 2011. More comparison study pairs with new lesions and improved lesions were recorded by using the software compared with original radiology reports.

- Woven EndoBridge Intrasaccular Flow Disrupter for the Treatment of Ruptured and Unruptured Wide-Neck Cerebral Aneurysms: Report of 55 Cases
This is a retrospective study of all ruptured and unruptured aneurysms that were treated with a WEB device (WEB Dual-Layer, Single-Layer, and Single-Layer Sphere) between April 2012 and August 2014 at 2 centers. Fifty-five aneurysms in 52 patients, including 14 ruptured aneurysms, underwent treatment with the WEB device. A favorable angiographic result at 3 months was achieved in 66% of cases, whereas the percentage of good anatomic results increased from 40% in 2012 to 75% in 2014.
