      The Restless Spinal Cord in Degenerative Cervical Myelopathy
      M. Hupp, N. Pfender, K. Vallotton, J. Rosner, S. Friedl, C.M. Zipser, R. Sutter, M. Klarhöfer, J.M. Spirig, M. Betz, M. Schubert, P. Freund, M. Farshad and A. Curt

      Patients with degenerative cervical myelopathy show altered spinal cord motion with increased and ongoing oscillations at and also beyond the focal level of stenosis. Phase-contrast MR imaging has promise as a biomarker to reveal mechanical stress to the cord.

      Real-Time Ultrasound Image Fusion with FDG-PET/CT to Perform Fused Image-Guided Fine-Needle Aspiration in Neck Nodes: Feasibility and Diagnostic Value
      P.K. de Koekkoek-Doll, M. Maas, W. Vogel, J. Castelijns, L. Smit, I. Zavrakidis, R. Beets-Tan and M. van den Brekel
      American Journal of Neuroradiology March 2021, 42 (3) 566-572; DOI: https://doi.org/10.3174/ajnr.A6938

      Real-time ultrasound image fusion with FDG-PET-positive nodes is feasible in cervical lymph nodes, and fused ultrasound-guided fine-needle aspiration increases the number of malignant nodes detected.

      Reliability of the Diagnosis of Cerebral Vasospasm Using Catheter Cerebral Angiography: A Systematic Review and Inter- and Intraobserver Study
      T.E. Darsaut, C. Derksen, B. Farzin, M.B. Keough, R. Fahed, W. Boisseau, L. Letourneau-Guillon, A.-C. Januel, A. Weill, D. Roy, T.N. Nguyen, S. Finitsis, J.-C. Gentric, D. Volders, A.

      This systematic review showed a very heterogeneous literature, with 140 studies using 60 different nomenclatures and 21 different thresholds to define cerebral vasospasm, and 5 interobserver studies reporting a wide range of reliability. Research on cerebral vasospasm would benefit from standardization of definitions and thresholds. Dichotomized decisions by experienced readers are required for the reliable angiographic diagnosis of cerebral vasospasm.
