    “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.

    State of Practice: ASNR Statement on Gadolinium-Based Contrast Agent Use in Patients with Chronic Kidney Disease
    Kirk M. Welker, David Joyner, Anthony W. Kam, David S. Liebeskind, Amit M. Saindane, Colin Segovis, Noushin Yahyavi-Firouz-Abadi and John E. Jordan
    American Journal of Neuroradiology February 2025, 46 (2) 227-230; DOI: https://doi.org/10.3174/ajnr.A8501

    The ASNR Standards and Guidelines Committee reviewed new research evidence on GBCA safety and its relevance to current MRI contrast administration guidelines for patients with CKD. The recommendations for CKD patients are that there is no longer a need to withhold group II GBCAs when medically indicated for diagnosis and that it is not necessary to check renal function for these agents.

    This is an updated comprehensive review of the various myelographic techniques that can be used to identify CSF-venous fistulas. The authors discuss the advantages and disadvantages of each and describe provocative maneuvers that may improve the conspicuity of CVFs.

    The Association of Vascular Loops within the Internal Auditory Meatus or Contacting the Vestibulo-Cochlear Nerve with Audiovestibular Symptoms: A Systematic Review and Meta-Analysis
    Jake E. Cowen, Mehrshad Sultani Tehrani and Steve E.J. Connor
    American Journal of Neuroradiology February 2025, 46 (2) 372-379; DOI: https://doi.org/10.3174/ajnr.A8486

    This systematic review and meta-analysis aimed to determine whether the presence of IVLs and CN VIII NVC on MRI is associated with tinnitus, SNHL, or vertigo and any specific subtypes. It was found that CN VIII NVC is associated with vestibular paroxysmia, and IVL is associated with sudden-onset SNHL. No association was found between IVL or CN VIII NVC and undefined tinnitus, SNHL, and vertigo.
