      Temporal Characteristics of CSF-Venous Fistulas on Dynamic Decubitus CT Myelography: A Retrospective Multi-Institution Cohort Study

      This retrospective multi-institution cohort study analyzed the temporal features of CSF-venous fistula (CVF) visualization on dynamic decubitus CT myelography (dCTM) in 48 patients. The results showed that most CVFs were visible on first or subsequent phases of dCTM, but approximately 1 in 8 were only visible on either the early or delayed phase. The authors conclude that acquiring greater than 1 phase of imaging increases the sensitivity of dCTM by increasing its temporal resolution.

      CTA and CTP for Detecting Distal Medium Vessel Occlusions: A Systematic Review and Meta-analysis
      João André Sousa, Anton Sondermann, Sara Bernardo-Castro, Ricardo Varela, Helena Donato and João Sargento-Freitas
      American Journal of Neuroradiology January 2024, 45 (1) 51-56; DOI: https://doi.org/10.3174/ajnr.A8080

      This systematic review and meta-analysis aimed to compare the diagnostic test accuracy for CTA and CTP in the detection of distal medium vessel occlusion. The study found consistent evidence for a higher sensitivity in detecting distal medium vessel occlusion, particularly in arteries beyond the M2 segment of MCA, with multiphase CTA or CTP compared with single-phase CTA.

      The Choroid Plexus as an Alternative Locus for the Identification of the Arterial Input Function for Calculating Cerebral Perfusion Metrics Using MRI

      American Journal of Neuroradiology January 2024, 45 (1) 44-50; DOI: https://doi.org/10.3174/ajnr.A8099

      MR imaging-based cerebral perfusion metrics can be obtained by tracing a contrast bolus through the brain microvasculature. The authors compared the calculated resting relative perfusion metrics obtained from the choroid plexus (CP) with those obtained from the middle cerebral artery (MCA) in healthy participants and patients with glioma. The findings of this study suggest that an arterial input function chosen from within the CP is comparable with one chosen from the MCA and may be an alternative, particularly when there is no suitable MCA location to interrogate.
