- CT Perfusion Does Not Modify the Effect of Reperfusion in Patients with Acute Ischemic Stroke Undergoing Endovascular Treatment in the ESCAPE-NA1 Trial
Various CTP metrics are used as biomarkers of ischemia and clinical outcomes in some patients undergoing EVT. This post hoc analysis of the Safety and Efficacy of Nerinetide in Subjects Undergoing Endovascular Thrombectomy for Stroke (ESCAPE-NA1) trial shows that patients having undergone EVT with baseline small CTP lesion volumes have a better clinical outcome compared with those with larger CTP lesions. However, CTP was not able to elucidate why some patients have poor outcomes despite near-complete recanalization.
- Brain Maturation Patterns on Normalized FLAIR MR Imaging in Children and Adolescents
Studies to date have shown signal maturation patterns in the pediatric population using various sequences. However, there is a paucity of information about brain maturation patterns of FLAIR signal intensities across the pediatric range. Additionally, intensities vary widely across FLAIR MR imaging scanners. A FLAIR intensity standardization algorithm would be helpful to normalize intensity across large data sets, allowing comparison of FLAIR intensity in different regions and individuals.

This is an illustrative review of neuroimaging manifestations of EBV-associated infectious, noninfectious inflammatory, and lymphoproliferative disorders, which have a myriad of imaging appearances.
- Reliable Initial Trauma CT Findings of Supraclavicular Brachial Plexus Injury in Patients Sustaining Blunt Injuries
A case (n = 36) - control (n = 50) study aimed to identify CT findings of supraclavicular brachial plexus injuries to discern who may require further evaluation with MR imaging. The results showed that scalene muscle edema/enlargement and interscalene fat pad effacement were most strongly associated with brachial plexus injury and demonstrated good sensitivity and specificity. These findings are best assessed with a soft-tissue reconstruction kernel; therefore, this should be incorporated as part of the trauma CT cervical spine assessment.
