    β-Trace Protein as a Potential Biomarker for CSF-Venous Fistulas
    Ian T. Mark, Waleed Brinjikji, Jeremy Cutsforth-Gregory, Jared T. Verdoorn, John C. Benson, Ajay A. Madhavan and Jeff W. Meeusen
    American Journal of Neuroradiology February 2025, 46 (2) 416-420; DOI: https://doi.org/10.3174/ajnr.A8476

    This prospective study of patients with CVF compared the levels of β-trace protein (BTP) in paraspinal veins near the CVF with those in the peripheral blood and in the peripheral blood of controls. Venous blood at the site of the CVF was shown to have higher BTP values compared with peripheral blood in most patients with CVF. It was also found that patients with CVF had a lower peripheral blood BTP level compared with controls.

    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.

    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.

    “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.

    Comprehensive Review of Inner Ear Anatomy on Photon-Counting CT
    Dinesh Rao, John V. Murray, Amit K. Agarwal, Sukhwinder Johnny Sandhu and Pat A. Rhyner
    American Journal of Neuroradiology May 2025, 46 (5) 862-867; DOI: https://doi.org/10.3174/ajnr.A8410

    Compared to traditional energy-integrating CT detectors, photon-counting CT allows greater spatial and contrast resolution of small channels containing nerves, arteries, and normal anatomy such as the cochlear cleft and cochlear and vestibular aqueducts. This review article updates the existing literature by redefining these structures in greater resolution.
