Introduction To assess an optimized 3D imaging protocol for intracranial nitinol stents in 3D C-arm flat detector imaging. For this purpose, an image quality simulation and an in vitro study was carried out. Neuroradiology (2012) 54:155–162. Copyright The Author(s) 2011.

Purpose: To evaluate the feasibility, efficacy, and safety of percutaneous vertebroplasty (PV) in the treatment of pathologic fractures owing to malignancy with epidural involvement, with or without neurologic symptoms of spinal cord or cauda equina compression. March 2010 Radiology: 254, 882-890. Copiryght © RSNA, 2010
Purpose: To compare the safety and efficacy of the remodeling technique with that of conventional coil embolization in a large multicenter series involving the endovascular treatment of ruptured intracranial aneurysms, the CLARITY study (Clinical and Anatomic Results in the Treatment of Ruptured Intracranial Aneurysms).

Purpose: To evaluate the effectiveness and safety of transarterial glue embolization of intracranial dural arteriovenous shunts (DAVS). February 2011 Radiology: 258, 554-561. Copyright © RSNA, 2011
Background and Purpose—Acute ischemic stroke due to tandem occlusions of the extracranial internal carotid artery and intracranial arteries has a poor natural history. We aimed to evaluate our single-center experience with endovascular treatment of this unique stroke population. Stroke. 2011; 42: 1653-1657 Published online before print April 21, 2011.

BACKGROUND AND PURPOSE: FD stent placement is a promising therapy for challenging intracranial aneurysms. Long-term evaluations about angiographic and morphologic results are still missing. This is the aim of this multicenter series. Published online before print February 2, 2012, doi: 10.3174/ajnr.A2907. Copyright © 2012 American Society of Neuroradiology

La excelencia en la práctica clínica diaria exige la aplicación de decisiones médicas basadas en la evidencia científica. El nivel máximo de evidencia científica procede de estudios prospectivos multicéntricos aleatorizados que permitan una generalización de los resultados, extensibles a la comunidad científica. El adecuado diseño de dichos estudios, necesarios para la validación de toda nueva alternativa terapéutica, requiere la recopilación de información previa, obtenida de estudios de observación que se convierten, de este modo, en una fuente de información para la toma de decisiones en la práctica diaria; ello hasta disponer de los datos aportados por los estudios multicéntricos que, no obstante, deben interpretarse con cautela, ya que sus resultados no se extrapolan siempre a cualquier población y ámbito de ejercicio profesional.
[+]Intracranial stent placement assists in the coiling of wide-neck aneurysms and aids in reconstructing and protecting the parent artery. In this study, we analyze our experience in the use of the Neuroform system. AJNR Am J Neuroradiol 2011 32: 31-136 originally published online on October 21, 2010, 10.3174/ajnr.A2245.
Hemodynamics are thought to play an important role in the mechanisms of aneurysm pathogenesis, progression, and rupture. The purpose of this study was to define quantitative measures related to qualitative flow characteristics previously analyzed and to investigate their relationship to aneurysm rupture. AJNR Am J Neuroradiol 2011 32: 145-151originally published online on December 2, 2010, 10.3174/ajnr.A2419.
Retrievable stents combine the high recanalization rate of stents and the capability of removing the thrombus offered by mechanical thrombectomy devices. We hypothesized that retrievable stents shorten time to recanalization in the multimodal approach for endovascular stroke treatment.

Flow-diverter stents are an alternative treatment for challenging and recurrent aneurysms. Thrombosis of the sac is thought to induce perianeurysmal brain inflammation, but such phenomena have never been studied in flow-diverter devices. We developed imaging data to explain the clinical exacerbation of symptoms after flow-diversion treatment. AJNR Am J Neuroradiol 2011 32: 1930-1934originally published online on September 22, 2011, 10.3174/ajnr.A2710.
Until now, endovascular treatment of symptomatic atherosclerotic stenosis in small intracranial arteries (< = 2.5 mm) was limited. We evaluated the safety and efficacy of the treatment by using Wingspan stents in arteries of this caliber. AJNR Am J Neuroradiol 2012 33: 343-347originally published online on December 15, 2011, 10.3174/ajnr.A2772.
There are only a few reports on the feasibility and safety of stents used in the PICA, and clinical and angiographic follow-up results have not been fully addressed. We report our experiences of treating PICA origin or vertebral arteryPICA lesions by using self-expanding stents as adjuvant or rescue therapy with angiographic and clinical follow-up results.
