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.

- EDITOR'S CHOICEPediatricsOpen AccessBrain Maturation Patterns on Normalized FLAIR MR Imaging in Children and AdolescentsK. Chan, A. Ghazvanchahi, D. Rabba, L. Vidarsson, M.W. Wagner, B.B. Ertl-Wagner and A. KhademiAmerican Journal of Neuroradiology September 2023, 44 (9) 1077-1083; DOI: https://doi.org/10.3174/ajnr.A7966
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.

- FELLOWS' JOURNAL CLUBSpineOpen AccessValidity of the Bern Score as a Surrogate Marker of Clinical Severity in Patients with Spontaneous Intracranial HypotensionJ.L. Houk, S. Morrison, S. Peskoe, T.J. Amrhein and P.G. KranzAmerican Journal of Neuroradiology September 2023, 44 (9) 1096-1100; DOI: https://doi.org/10.3174/ajnr.A7962
The Bern score quantitatively characterizes brain MR imaging changes in spontaneous intracranial hypotension. This imaging biomarker was shown to have a low correlation with clinical headache severity and, therefore, imaging findings in isolation may have limited utility as primary outcome measures when assessing treatment response.
