      The T2-FLAIR mismatch sign on MR imaging, usually determined by visual assessment, is a highly specific imaging biomarker of IDH-mutant astrocytomas. The authors of this study quantified the degree of T2-FLAIR mismatch in nonenhancing diffuse gliomas. Thresholds of ≥42% T2-FLAIR mismatch volume classified IDH-mutant astrocytoma with a specificity/sensitivity of 100%/19.6% (TCIA) and 100%/31.6% (institutional). They also found that grades 3–4 compared with grade 2 IDH-mutant astrocytomas (P<.05) had a higher percentage T2-FLAIR mismatch volume.

      This study quantitatively evaluated the performance of natural language processing models using real, longitudinal brain aneurysm imaging reports to objectively understand the strength and weakness of these new technologies.

      Diffusion-Weighted Imaging Reveals Impaired Glymphatic Clearance in Idiopathic Intracranial Hypertension

      American Journal of Neuroradiology February 2024, 45 (2) 149-154; DOI: https://doi.org/10.3174/ajnr.A8088

      The diffusivity along the cerebral perivascular spaces (DTI-ALPS technique) and lateral association and projection fibers in patients with IIH were compared with normal controls. Using the degree of diffusivity as a surrogate for glymphatic function, IIH patients were shown to have a significantly lower glymphatic clearance compared with controls (P=.005), with a significant association between declining glymphatic clearance and increasing Frisen papilledema grade (P=.046).

      Discrimination of Hemorrhage and Contrast Media in a Head Phantom on Photon-Counting Detector CT Data
      Franka Risch, Ansgar Berlis, Thomas Kroencke, Florian Schwarz and Christoph J. Maurer
      American Journal of Neuroradiology February 2024, 45 (2) 183-187; DOI: https://doi.org/10.3174/ajnr.A8093

      Photon-counting detector CT acquires spectral information that allows for material differentiation. CT scan can be separated into the attenuation resulting from remaining iodine and soft tissue, generating contrast media maps and virtual noncontrast series. In this study, the authors demonstrated that PCD-CT can reliably differentiate between blood and iodine and accurately determine several iodine concentrations in an anthropomorphic head phantom.
