      Lumbar Spinal Stenosis Severity by CT or MRI Does Not Predict Response to Epidural Corticosteroid versus Lidocaine Injections
      F.A. Perez, S. Quinet, J.G. Jarvik, Q.T. Nguyen, E. Aghayev, D. Jitjai, W.D. Hwang, E.R. Jarvik, S.S. Nedeljkovic, A.L. Avins, J.M. Schwalb, F.E. Diehn, C.J. Standaert, D.R. Nerenz, T. Annaswamy, Z. Bauer, D. Haynor, P.J. Heagerty and J.L. Friedly

      In this secondary analysis of the CT and MR imaging studies of the prospective, double-blind Lumbar Epidural Steroid Injections for Spinal Stenosis (LESS) trial participants, the authors found no differences in baseline imaging characteristics between those receiving epidural corticosteroid and lidocaine and those receiving lidocaine alone injections. No imaging measures of spinal stenosis were associated with a differential response to corticosteroids, indicating that imaging parameters of spinal stenosis did not predict a response to epidural corticosteroids.

      Usefulness of Silent MR Angiography for Intracranial Aneurysms Treated with a Flow-Diverter Device

      Silent MRA is a procedure using an ultrashort TE and arterial spin-labeling techniques, which efficiently visualizes the status after the treatment of intracranial aneurysms. In Silent MRA, the 3D image is reconstructed by subtracting the control image from the image obtained by the labeling pulse. Seventy-eight large, unruptured internal carotid aneurysms in 78 patients were the subjects of this study. After 6 months of treatment, they underwent follow-up digital subtraction angiography, Silent MRA, and TOF-MRA, performed simultaneously. The authors found Silent MRA is superior for visualizing blood flow images inside flow-diverter devices compared with TOF-MRA. Furthermore, Silent MRA enables the assessment of aneurysmal embolization status. Silent MRA is useful for assessing the status of large and giant unruptured internal carotid aneurysms after flow-diverter placement.
