To evaluate the effects of preoperative embolization on overall surgical outcomes after meningioma resection and determine whether pre- and postembolization tumor enhancement patterns on magnetic resonance imaging (MRI) scans can be used to assess the efficacy of embolization. ⋯ Pre- and postembolization tumor enhancement patterns on magnetic resonance imaging defined as EF correlate with improved surgical facilitation and postoperative functional outcomes in the management of intracranial meningioma.

To report a single-center experience in the endovascular management of cerebral aneurysms in children with stenting and flow-diversion techniques. ⋯ In this series, device-assisted endovascular techniques were a relatively safe and effective method of treatment of pediatric aneurysms. However, continued follow-up is required after treatment, because there are unsolved issues regarding the durability of flow-diverters and stents.

The aim of this study was to evaluate the differences in dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) perfusion estimates of high-grade brain gliomas (HGG) due to the use of an input function (IF) obtained respectively from arterial (AIF) and venous (VIF) approaches by two different commercially available software applications. ⋯ Direct comparison of DCE-MRI measurements with IF generated by means of arterial or venous waveform led to no statistical difference in quantitative metrics for evaluating HGG. However, additional research involving DCE-MRI acquisition protocols and post-processing would be beneficial to further substantiate the effectiveness of venous approach as the IF method compared with arterial-based IF measurement.

Headache after cerebral angiography is frequent but has received little attention. The purpose of this study was to evaluate the incidence and risk factors of headache after cerebral angiography. This study also addressed the predisposing factors that facilitate headache recovery. ⋯ The incidence of headache after DSA was 55.6%. Patients with a previous history of headaches, cerebrovascular disease, or a college education may have a higher risk of developing post-DSA headaches than do those without such history. Headache recovery may be associated with a patient history of diabetes or cerebrovascular disease.

The aim of this study was to investigate the characteristic pattern of age-related cortical thinning in patients with Down Syndrome (DS), as assessed by MRI and automatic cortical thickness measurements. ⋯ Our findings showed that Down Syndrome subjects are affected by a diffuse cortical thinning. The involvement of cortical structures can be observed at an earlier age than previous studies have reported.
