      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.

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

      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.
