    Distinguishing radiation necrosis from tumor progression after radiation therapy for brain metastases is challenging on conventional MRI. This study demonstrated higher normalized contrast-enhanced T1 and T2 FLAIR signal intensity for RN. Contrast-enhanced T2 FLAIR signal intensity distinguished RN and TP with an AUC similar to that of DSC perfusion.

    “Flow Void Sign”: Flow Artifact on T2-Weighted MRI Can Be an Indicator of Dural Defect Location in Ventral Type 1 Spinal CSF Leaks
    Lalani Carlton Jones, Diogo G.L. Edelmuth, David Butteriss and Daniel J. Scoffings
    American Journal of Neuroradiology January 2025, 46 (1) 211-218; DOI: https://doi.org/10.3174/ajnr.A8445

    Type 1 CSF leaks are commonly associated with ventral predominant epidural fluid. On 2D T2-weighted and STIR images, CSF-flow artifact in the anterior subarachnoid space and/or the adjacent epidural fluid collection at the level of the dural defect is caused by CSF-flow and may permit accurate prediction of the site of the CSF leak noninvasively.
