Journal ArticleDOI
Isolated demyelinating syndromes: comparison of CSF oligoclonal bands and different MR imaging criteria to predict conversion to CDMS
TL;DR: A high prevalence of OB in CIS is observed and OB and MR imaging (Paty's and Fazekas' criteria) have high sensitivity and Barkhof's criteria have a higher specificity.
Journal ArticleDOI
Hyperglycemia during Ischemia Rapidly Accelerates Brain Damage in Stroke Patients Treated with tPA
Marc Ribó,Carlos A. Molina,Pilar Delgado,Marta Rubiera,Raquel Delgado-Mederos,Alex Rovira,Josep Munuera,José Alvarez-Sabín +7 more
TL;DR: Hyperglycemia, especially during OT, has a powerful deleterious effect after stroke accelerating brain damage and is identified as the best predictor of poor outcome.
Journal ArticleDOI
High lipoprotein (a), diabetes, and the extent of symptomatic intracranial atherosclerosis.
Juan F. Arenillas,Carlos A. Molina,Pilar Chacón,Alex Rovira,Joan Montaner,Pilar Coscojuela,E. Sánchez,Manuel Quintana,José Alvarez-Sabín +8 more
TL;DR: High Lp(a) level and diabetes mellitus are independent markers of a greater extent of intracranial large-artery occlusive disease and might be useful for the selection of high-risk patients.
Journal ArticleDOI
Distribution territories and causative mechanisms of ischemic stroke
TL;DR: The different MR imaging patterns of acute ischemic brain lesions visualized using diffusion-weighted imaging and the pattern of vessel involvement demonstrated with MR angiography are essential factors that can suggest the most likely causative mechanism of infarction.
Journal ArticleDOI
Recommendations to improve imaging and analysis of brain lesion load and atrophy in longitudinal studies of multiple sclerosis
Hugo Vrenken,Mark Jenkinson,Mark A. Horsfield,Marco Battaglini,R.A. van Schijndel,Egill Rostrup,J. J. G. Geurts,Elizabeth Fisher,Alex P. Zijdenbos,John Ashburner,DH Miller,Massimo Filippi,Franz Fazekas,Marco Rovaris,Alex Rovira,Frederik Barkhof,N. De Stefano +16 more
TL;DR: Advice is made that images should be acquired using 3D pulse sequences, with near-isotropic spatial resolution and multiple image contrasts to allow more comprehensive analyses of lesion load and atrophy, across timepoints.
