- Cortically Based Brain Tumors in Children: A Decision-Tree Approach in the Radiology Reading Room
This comprehensive review of cortically based brain tumors in children proposes a decision tree to help with the differential diagnosis.
- Hemodynamic Characteristics in Ruptured and Unruptured Intracranial Aneurysms: A Prospective Cohort Study Utilizing the AneurysmFlow Tool
A DSA-based flow quantification tool (AneurysmFlow) was used to measure blood flow vectors and velocities after contrast injection. Complex flow patterns were shown to be common in ruptured aneurysms and those with daughter sacs. Lowest mean aneurysm flow amplitude in the dome and daughter sacs indicated pathophysiologic changes linked to rupture. Also, hypertension, bifurcation location, and irregular shape of unruptured aneurysm were found to be independent rupture risk factors.
- Alternative Venous Pathways: A Potential Key Imaging Feature for Early Diagnosis of Sturge-Weber Syndrome Type 1
In this retrospective review of children with SWS, the most prevalent lesions at the first MRI were subarachnoid varicose network and transmedullary veins. The dilated venous channels are an early compensatory mechanism, preceding abnormal pial contrast enhancement, atrophy, and calcification.
