      Mocioiu, Victor; de Barros, Nuno M. Pedrosa; Ortega Martorell, Sandra; Slotboom, Johannes; Knecht, Urspeter; Arús, Carles; Vellido Alcacena, Alfredo; Julià Sapé, Margarida (I6doc.com, 2016)
      Conference report
      Open Access
      Machine learning has provided, over the last decades, tools for knowledge extraction in complex medical domains. Most of these tools, though, are ad hoc solutions and lack the systematic approach that would be required to ...

      Article
      Restricted access - publisher's policy
      The medical analysis of human brain tumours commonly relies on indirect measurements. Among these, magnetic resonance imaging (MRI) and spectroscopy (MRS) predominate in clinical settings as tools for diagnostic assistance. ...
    • Early pseudoprogression and progression lesions in glioblastoma patients are both metabolically heterogeneous 

      Ungan, Gülnur; Pons Escoda, Albert; Ulinic, Daniel; Arus Caraltó, Carles; Ortega Martorell, Sandra; Olier Caparroso, Iván; Vellido Alcacena, Alfredo; Majós, Carles; Julia Sape, Margarida (John Wiley & sons, 2024-01-11)
      Article
      Open Access
      The standard treatment in glioblastoma includes maximal safe resection followed by concomitant radiotherapy plus chemotherapy and adjuvant temozolomide. The first follow-up study to evaluate treatment response is performed ...
    • Extraction of artefactual MRS patterns from a large database using non-negative matrix factorization 

      Hernández Villegas, Yanisleydis; Ortega Martorell, Sandra; Arus Caraltó, Carles; Vellido Alcacena, Alfredo; Julia Sape, Margarida (2022-04)
      Article
      Open Access
      Despite the success of automated pattern recognition methods in problems of human brain tumor diagnostic classification, limited attention has been paid to the issue of automated data quality assessment in the field of MRS ...
