      Article
      Accés obert
      The study of the colonic volume is a procedure with strong relevance to gastroenterologists. Depending on the clinical protocols, the volume analysis has to be performed on MRI of the unprepared colon without contrast ...

      Article
      Accés obert
      BACKGROUND & AIMS: In patients with functional gut disorders, abdominal distension has been associated with descent of the diaphragm and protrusion of the anterior abdominal wall. We investigated mechanisms of abdominal ...

    • Colonic content assessment from MRI imaging using a semi-automatic approach 

      Ceballos Inza, Víctor; Monclús Lahoya, Eva; Vázquez Alcocer, Pere Pau; Bendezú García, Álvaro; Mego Silva, Marianela; Merino Casabiel, Xavier; Azpiroz Vidaur, Fernando; Navazo Álvaro, Isabel (European Association for Computer Graphics (Eurographics), 2019)
      Text en actes de congrés
      Accés obert
      The analysis of the morphology and content of the gut is necessary in order to achieve a better understanding of its metabolic and functional activity. Magnetic resonance imaging (MRI) has become an important imaging ...

    • Colonic content in health and its relation to functional gut symptoms 

      Bendezú García, Álvaro; Barba, Elisabeth; Burri, Emanuel; Cisternas, Daniel; Accarino Garaventa, Anna María; Quiroga, Sergi; Monclús Lahoya, Eva; Navazo Álvaro, Isabel; Malagelada Benapres, Juan Ramon; Azpiroz Vidaur, Fernando (2016-02-12)
      Article
      Accés obert
      Gut content may be determinant in the generation of digestive symptoms, particularly in patients with impaired gut function and hypersensitivity. Since the relation of intraluminal gas to symptoms is only partial, we ...

    • Colonic content: effect of diet, meals, and defecation 

      Bendezú García, Álvaro; Mego, Marianela; Monclús Lahoya, Eva; Merino, Xavi; Accarino Garaventa, Anna María; Malagelada Benapres, Juan Ramon; Navazo Álvaro, Isabel; Azpiroz Vidaur, Fernando (2017-01-29)
      Article
      Accés obert
      The metabolic activity of colonic microbiota is influenced by diet; however, the relationship between metabolism and colonic content is not known. Our aim was to determine the effect of meals, defecation, and diet on colonic ...
