    According to clinical studies, around one third of patients with atrial fibrillation (AF) will suffer a stroke during their lifetime. Between 70 and 90% of these strokes are caused by thrombus formed in the left atrial ...
  • Sanromà, Gerard; Benkarim, Oualid M.; Piella Fenoy, Gemma; Camara, Oscar; Wu, Guorong; Shen, Dinggang; Gispert, Juan D.; Molinuevo, José Luis; González Ballester, Miguel Ángel, 1973- (Elsevier, 2018)
    In brain structural segmentation, multi-atlas strategies are increasingly being used over single-atlas strategies because of their ability to fit a wider anatomical variability. Patch-based label fusion (PBLF) is a type ...
  • Imre Sarvari, Sebastian; Rodriguez López, Mérida; Nuñez-Garcia, Marta; Sitges, Marta; Sepulveda-Martinez, Alvaro; Camara, Oscar; Butakoff, Constantine; Gratacós Solsona, Eduard; Bijnens, Bart; Crispi Brillas, Fàtima (American Hearth Association, 2017)
    Fetal growth restriction (FGR) affects 5% to 10% of newborns and is associated with increased cardiovascular mortality in adulthood. We evaluated whether prenatal cardiovascular changes previously demonstrated in FGR persist ...
