    Previously only defined by postmortem analysis, the use of flat panel catheter angiotomography allows definition of spinal cord transmedullary venous anastomoses.

    Incidence of Inadvertent Intravascular Injection during CT Fluoroscopy–Guided Epidural Steroid Injections
    P.G. Kranz, T.J. Amrhein and L. Gray
    American Journal of Neuroradiology May 2015, 36 (5) 1000-1007; DOI: https://doi.org/10.3174/ajnr.A4219

    Retrospective analysis of 575 CT fluoroscopy-guided epidural injections was done to detect inadvertent arterial or venous injections. Intravascular injections occurred in 26% of cervical transforaminal injections, 9% of cervical interlaminar injections, 8% of lumbar transforaminal injections, and 2% of lumbar interlaminar injections. These findings are similar to previous reports using conventional fluoroscopy and demonstrate that intravascular injections may be detected with CT fluoroscopy.

    Validation of Multisociety Combined Task Force Definitions of Abnormal Disk Morphology
    C.H. Cho, L. Hsu, M.L. Ferrone, D.A. Leonard, M.B. Harris, A.A. Zamani and C.M. Bono
    American Journal of Neuroradiology May 2015, 36 (5) 1008-1013; DOI: https://doi.org/10.3174/ajnr.A4212

    Fifty-four patients underwent classification of lumbar disk herniations during preoperative MRI and surgery using the new multisociety classification. Disagreement as to classification based on MRI studies occurred in only 1 instance and agreement of preoperative classification with operative findings was 70%. The authors believe that though this level of agreement is reasonable, differences exist between what neuroradiologists see on imaging and what surgeons encounter.

    Systematic Literature Review of Imaging Features of Spinal Degeneration in Asymptomatic Populations
    W. Brinjikji, P.H. Luetmer, B. Comstock, B.W. Bresnahan, L.E. Chen, R.A. Deyo, S. Halabi, J.A. Turner, A.L. Avins, K. James, J.T. Wald, D.F. Kallmes and J.G. Jarvik
    American Journal of Neuroradiology April 2015, 36 (4) 811-816; DOI: https://doi.org/10.3174/ajnr.A4173

    This meta-analysis of the literature reveals that imaging findings of spine degeneration are present in high proportions of asymptomatic individuals, increasing with age. Many imaging-based degenerative features are likely part of normal aging and unassociated with pain.

    Percutaneous Injection of Radiopaque Gelified Ethanol for the Treatment of Lumbar and Cervical Intervertebral Disk Herniations: Experience and Clinical Outcome in 80 Patients
    M. Bellini, D.G. Romano, S. Leonini, I. Grazzini, C. Tabano, M. Ferrara, P. Piu, L. Monti and A. Cerase
    American Journal of Neuroradiology March 2015, 36 (3) 600-605; DOI: https://doi.org/10.3174/ajnr.A4166

    Eighty lumbar and 9 cervical spine herniations were treated with percutaneous intradiskal injection of gelified ethanol under fluoroscopy with 36 injections made simultaneously for 2 disk herniations. Post treatment symptom improvement was reported by 85% of patients with lumbarand 83% of those with cervical disk herniations.
