      The diffusion-weighted magnetic resonance imaging (DWI) technique enables quantification of water mobility for probing microstructural properties of biological tissue and has become an effective tool for collecting information ...

    • Development and aging of cortical thickness correspond to genetic organization patterns 

      Fjell, Anders Martin; Grydeland, Håkon; Krogsrud, Stine Kleppe; Amlien, Inge Kasbohm; Rohani, Darius Adam; Ferschmann, Lia; Storsve, Andreas Berg; Tamnes, Christian Krog; Sala-Llonch, Roser; Due-Tønnessen, Paulina; Bjørnerud, Atle; Sølsnes, Anne Elisabeth; Håberg, Asta; Skranes, Jon Sverre; Bartsch, Hauke; Chen, Chi-Hua; Thompson, Wesley K.; Panizzon, Matthew S.; Kremen, William S.; Dale, Anders M.; Walhovd, Kristine B (Journal article; Peer reviewed, 2015)
      There is a growing realization that early life influences have lasting impact on brain function and structure. Recent research has demon- strated that genetic relationships in adults can be used to parcellate the cortex ...

    • Development of hippocampal subfield volumes from 4 to 22 years 

      Krogsrud, Stine Kleppe; Tamnes, Christian Krog; Fjell, Anders Martin; Amlien, Inge; Grydeland, Håkon; Sulutvedt, Unni; Due-Tønnessen, Paulina; Bjørnerud, Atle; Sølsnes, Anne Elisabeth; Håberg, Asta; Skrane, Jon Sverre; Walhovd, Kristine B (Journal article; Peer reviewed, 2014-06-30)
      The hippocampus supports several important cognitive functions known to undergo substantial development during childhood and adolescence, e.g. encoding and consolidation of vivid personal memories. However, diverging ...

    • Imaging the tumour microenvironment in rectal cancer: Decline in tumour blood flow during radiotherapy predicts good outcome 

      Bakke, Kine Mari; Meltzer, Sebastian; Grøvik, Endre; Negård, Anne; Holmedal, Stein Harald; Mikalsen, Lars Tore Gyland; Færden, Arne Engebreth; Lyckander, Lars Gustav; Julbø, Frida Marie Ihle; Bjørnerud, Atle; Gjesdal, Kjell Inge; Ree, Anne Hansen; Redalen, Kathrine Røe (Peer reviewed; Journal article, 2023)
      Background and purpose Measuring rectal tumour response to radiation is pivotal to restaging patients and for possibly stratification to a watch-and-wait strategy. Recognizing the importance of the tumour microenvironment, ...
