    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.

    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.

    Safety and Technical Performance of Bilateral Decubitus CT Myelography Using Standard versus Increased Intrathecal Iodinated Contrast Volume
    Diogo G.L. Edelmuth, Renata V. Leão, Eduardo N.K. Filho, Marcio N.P. Souza, Marcelo Calderaro and Peter G. Kranz
    American Journal of Neuroradiology February 2025, 46 (2) 401-407; DOI: https://doi.org/10.3174/ajnr.A8436

    In this retrospective study, the authors assessed the tolerability and technical performance of increased intrathecal doses (20 mL) of myelographic contrast compared with standard doses (10 mL). They found that the increased volume of intrathecal contrast was well-tolerated and improved the technical performance of LDCTM.

    Dynamic Expansion and Contraction of Multiple Sclerosis T2-Weighted Hyperintense Lesions Are Present below the Threshold of Visual Perception

    Recognition of longitudinal imaging changes of MS lesions has substantial implications for clinical management, but changes may remain below the resolution of human perception. In this study, the authors demonstrated that T2-weighted hyperintense lesions undergo dynamic change on MRI, with predominantly enlarging or contracting characteristics, more frequently seen in untreated individuals.
