  Efficacy and Safety of Flow Diversion for Paraclinoid Aneurysms: A Matched-Pair Analysis Compared with Standard Endovascular Approaches
  G. Lanzino, E. Crobeddu, H.J. Cloft, R. Hanel and D.F. Kallmes
  
  American Journal of Neuroradiology December 2012, 33 (11) 2158-2161; DOI: https://doi.org/10.3174/ajnr.A3207
  
  These seasoned investigators sought to evaluate the efficacy and safety of flow-diverting devices for the treatment of complex paraclinoid aneurysms in 21 patients and compared their results with historical matched controls treated at their institution. Aneurysm size, location, risk factors, and comorbidities were equal for both groups. In the hands of these authors, flow diverters achieved a higher rate of aneurysm obliteration when compared with other treatments and did not show an increased rate of complications.

  Autoimmune pancreatitis, sclerosing cholangitis and sialoadenitis, retroperitoneal and mediastinal fibrosis, and insterstitial pneumonia are all IgG-4 related disorders. This short article discusses the head and neck manifestations of this disease: orbital pseudotumor and lacrimal gland, cranial nerve, and pituitary involvement. Intracranially, the dura may be also affected. All of these lesions were contrast-enhancing and T2 dark, findings to be kept in mind so that one can suggest their etiology.

  Characterizing Hypervascular and Hypovascular Metastases and Normal Bone Marrow of the Spine Using Dynamic Contrast-Enhanced MR Imaging

  American Journal of Neuroradiology December 2012, 33 (11) 2178-2185; DOI: https://doi.org/10.3174/ajnr.A3104
  
  In this study the feasibility of using dynamic postcontrast imaging to separate hypo- and hypervascular spine metastases was assessed. Using a T1 postcontrast sequence with temporal resolution of 6 seconds, the authors imaged spine lesions in 26 patients and from the data collected calculated 3 dynamic parameters. Hypervascular lesions showed steeper and higher wash-in slopes and higher peak enhancement. Conversely, conventional pre- and postcontrast images were unable to differentiate lesions.

  A Comparison of Radiation Exposure between Diagnostic CTA and DSA Examinations of Cerebral and Cervicocerebral Vessels
  A.-L. Manninen, J.-M. Isokangas, A. Karttunen, T. Siniluoto and M.T. Nieminen
  
  American Journal of Neuroradiology December 2012, 33 (11) 2038-2042; DOI: https://doi.org/10.3174/ajnr.A3123
  
  This article compares radiation exposure from CTA and DSA used to evaluate the extra- and intracranial circulations. Experiments were performed on a phantom using a 64-section CT scanner and biplane DSA. The authors concluded that the effective dose for CTA assessment of cerebral vessels was approximately one-fifth the dose compared with DSA. In the imaging of cervicocerebral vessels, the effective dose for CTA was approximately one-third higher compared with DSA.
