    • Quantitative PET/MR imaging of lung cancer in the presence of artifacts in the MR-based attenuation correction maps 

      Kuttner, Samuel; Lassen, Martin Lyngby; Øen, Silje Kjærnes; Sundset, Rune; Beyer, Thomas; Eikenes, Live (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-13)
      <i>Background</i> - Positron emission tomography (PET)/magnetic resonance (MR) imaging may become increasingly important for assessing tumor therapy response. A prerequisite for quantitative PET/MR imaging is reliable and repeatable MR-based attenuation correction (AC).<p> <p><i>Purpose</i> - To investigate the frequency and test–retest reproducibility of artifacts in MR-AC maps in a lung cancer ...

    • Unsupervised supervoxel-based lung tumor segmentation across patient scans in hybrid PET/MRI 

      Hansen, Stine; Kuttner, Samuel; Kampffmeyer, Michael; Markussen, Tom-Vegard; Sundset, Rune; Øen, Silje Kjærnes; Eikenes, Live; Jenssen, Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-29)
      Tumor segmentation is a crucial but difficult task in treatment planning and follow-up of cancerous patients. The challenge of automating the tumor segmentation has recently received a lot of attention, but the potential of utilizing hybrid positron emission tomography (PET)/magnetic resonance imaging (MRI), a novel and promising imaging modality in oncology, is still under-explored. Recent ...
