- Differences in Neuroradiology Training Programs around the World
Neuroradiology training information was collected from 43 countries via a questionnaire. No training programs are available in 16 and post residency curricula are available in 27. Although most training periods are 1–2 years, number of fellows and didactic education varies.

- White Matter Correlates of Cognitive Impairment in Essential Tremor
A series of 55 patients with essential tremor and an equal number of age-matched controls were assessed clinically and by DTI. Alterations in executive and visual spatial functions correlated with DTI measures suggesting an anatomic basis for cognitive impairment in these patients.
- Brain Metabolic Abnormalities Associated with Developmental Venous Anomalies
The authors reviewed 25 developmental venous anomalies imaged with MRI and FDG-PET. Metabolic abnormalities were found in 76%, most commonly adjacent brain hypometabolism. These findings were predominantly seen in older individuals.
- Impact of Time-to-Reperfusion on Outcome in Patients with Poor Collaterals
More than 200 patients with MCA +/- ICA occlusions who successfully reperfused with endovascular techniques were assessed. The probability of good outcome was not significantly influenced by onset-to-reperfusion and puncture-to-reperfusion periods in patients with good collaterals but dropped significantly in patients with poor collaterals.

- Conscious Sedation versus General Anesthesia during Endovascular Acute Ischemic Stroke Treatment: A Systematic Review and Meta-Analysis
Nine studies encompassing nearly 2000 patients treated with or without anesthesia for acute stroke were analyzed. Patients with acute ischemic stroke undergoing intra-arterial therapy may have worse outcomes with general anesthesia compared with conscious sedation. However, the difference in stroke severity at the onset may confound the comparison in the available studies.

- Percutaneous Injection of Radiopaque Gelified Ethanol for the Treatment of Lumbar and Cervical Intervertebral Disk Herniations: Experience and Clinical Outcome in 80 Patients
Eighty lumbar and 9 cervical spine herniations were treated with percutaneous intradiskal injection of gelified ethanol under fluoroscopy with 36 injections made simultaneously for 2 disk herniations. Post treatment symptom improvement was reported by 85% of patients with lumbarand 83% of those with cervical disk herniations.
