      Background Relative enhanced diffusivity (RED) is a potential biomarker for indirectly measuring perfusion in tissue using diffusion‐weighted magnetic resonance imaging (MRI) with 3 b values. Purpose To optimize the RED ...

    • The Reproducibility of Deep Learning-Based Segmentation of the Prostate Gland and Zones on T2-Weighted MR Images 

      Sunoqrot, Mohammed R. S.; Selnæs, Kirsten Margrete; Sandsmark, Elise; Langørgen, Sverre; Bertilsson, Helena; Bathen, Tone Frost; Elschot, Mattijs (Peer reviewed; Journal article, 2021)
      Volume of interest segmentation is an essential step in computer-aided detection and diagnosis (CAD) systems. Deep learning (DL)-based methods provide good performance for prostate segmentation, but little is known about ...

    • Simultaneous 18F-fluciclovine Positron Emission Tomography and Magnetic Resonance Spectroscopic Imaging of Prostate Cancer 

      Esmaeili, Morteza; Tayari, Nassim; Scheenen, Tom WJ; Elschot, Mattijs; Sandsmark, Elise; Bertilsson, Helena; Heerschap, Arend; Selnæs, Kirsten Margrete; Bathen, Tone Frost (Journal article; Peer reviewed, 2018)
