Sixty-six patients with brain tumors were evaluated with resting-state fMRI using seed-based analysis of hand and orofacial motor regions. Rates of supplementary motor area localization were compared with those in healthy controls and with localization results by task-based fMRI. Localization of the supplementary motor area using hand motor seed regions was more effective than seeding using orofacial motor regions for both patients with brain tumor and controls. Bilateral hand motor seeding was superior to unilateral hand motor seeding in patients with brain tumor for either side. The authors conclude that in addition to task-based fMRI, seed-based analysis of resting-state fMRI represents an equally effective method for supplementary motor area localization in patients with brain tumors, with the best results obtained with bilateral hand motor region seeding.

Contextual reporting is an alternative method of structured reporting that is specifically related to the disease or examination indication. These disease-specific reports provide content focused on the clinical diagnosis or symptom, discuss appropriate differential diagnoses, and highlight pertinent positives and negatives. The authors created a library of 50 contextual structured reports for neuroradiologists and emphasize their clinical value over noncontextual structured reporting.

Thirty-five patients with high-grade, symptomatic intracranial stenosis and poor antegrade flow, treated with intracranial angioplasty without stent placement from January 2010 to December 2016, were retrospectively reviewed. The main outcomes included the changes in antegrade flow and residual stenosis and any stroke or death within 1 month. The average preprocedure stenosis was 88%. The immediate, average postprocedure stenosis rate was 25%, and the average postprocedure stenosis rate at last angiographic follow-up was 35%. The primary end point of major stroke or death at 30 days was observed in 1 patient (1/35, 2.9%), and no patient had intraprocedural complications. The authors conclude that primary balloon angioplasty was an effective treatment option for symptomatic intracranial stenosis with a high risk of stroke.
