Journal ArticleDOI
Brain volumetry counterparts of cognitive impairment in patients with multiple sclerosis
Jaume Sastre-Garriga,María Jesús Arévalo,Marta Renom,J. Alonso,I. González,Ingrid Galán,Xavier Montalban,Alex Rovira +7 more
TL;DR: Quantitative tissue-specific atrophy measures may display better correlations with patients' variables than regional grey matter atrophy distribution obtained using VBM methodology, and should be confirmed in larger samples.
Journal ArticleDOI

TL;DR: In this paper, the authors compared the generalized boundary shift integral (GBSI) with a standard segmentation-based method, and found that GBSI performed better than CSA in differentiating healthy controls from clinically isolated syndrome (CIS), relapsing-remitting MS (RRMS), 34 progressive MS (PMS), and 82 controls from 8 MAGNIMS (Magnetic Resonance Imaging in Multiple Sclerosis) sites on multimanufacturer and multi-field-strength scans.
Journal ArticleDOI
Biexponential analysis of diffusion-tensor imaging of the brain in patients with cirrhosis before and after liver transplantation.
L. Chavarria,Juli Alonso,Rita García-Martínez,F. X. Aymerich,E. Huerga,Carlos Jacas,Victor Vargas,J. Córdoba,Alex Rovira +8 more
TL;DR: Biexponential analysis of DTI supports the presence of edema in the brain of patients with cirrhosis that reverts after transplantation, and in parietal white matter, the increase in brain water was mainly located in the interstitial compartment, while the corticospinal tract showed a mixed pattern.
Journal ArticleDOI
MRI phenotypes with high neurodegeneration are associated with peripheral blood B-cell changes
Manuel Comabella,Ester Cantó,Ramil N. Nurtdinov,Jordi Río,Luisa M. Villar,Carmen Picón,Joaquín Castilló,Nicolás Fissolo,Xavier Aymerich,Cristina Auger,Alex Rovira,Xavier Montalban +11 more
TL;DR: The results suggest that RRMS patients with radiological phenotypes showing high neurodegeneration have changes in B cells characterized by down-regulation of B-cell-specific genes and increased activation status.
Journal ArticleDOI
Recommendations for the radiological diagnosis and follow-up of neuropathological abnormalities associated with tuberous sclerosis complex
Alex Rovira,María Luz Ruiz-Falcó,Elena García-Esparza,Eduardo López-Laso,Alfons Macaya,Ignacio Málaga,Elida Vazquez,Josefina Vicente +7 more
TL;DR: A group of experts in this field has reviewed different aspects related to these issues and put together, a series of statements and recommendations intended to provide guidance to specialists involved in the management of TSC.
