- Safety and Technical Performance of Bilateral Decubitus CT Myelography Using Standard versus Increased Intrathecal Iodinated Contrast Volume
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.
- 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
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.
- State of Practice: ASNR Statement on Gadolinium-Based Contrast Agent Use in Patients with Chronic Kidney Disease
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.
