    • A Retrospective Follow-up Study of Patients with Negative Multiparametric Prostate MRI 

      Jensen, Audun Bakke (Master thesis, 2023)
      Bakgrunn: Det er ikke allment akseptert at det er trygt og ønskelig å avstå fra biopsi i tilfeller av negativ multiparametrisk MR (mpMR) av prostata hos biopsinaive menn. Denne studien er en retrospektiv oppfølgingsstudie ...

    • A comparison of Generative Adversarial Networks for automated prostate cancer detection on T2-weighted MRI 

      Patsanis, Alexandros; Sunoqrot, Mohammed R. S.; Langørgen, Sverre; Wang, Hao; Selnæs, Kirsten Margrete; Bertilsson, Maria Helena; Bathen, Tone Frost; Elschot, Mattijs (Journal article; Peer reviewed, 2023)
      Generative Adversarial Networks (GANs) have shown potential in medical imaging. In this study, several previously developed GANs were investigated for prostate cancer (PCa) detection on T2-weighted (T2W) magnetic resonance ...

    • Detection of recurrent prostate cancer with 18F-Fluciclovine PET/MRI 

      Selnæs, Kirsten Margrete; Krüger-Stokke, Brage; Elschot, Mattijs; Johansen, Håkon; Steen, Per Arvid; Langørgen, Sverre; Aksnessæther, Bjørg Yksnøy; Indrebø, Gunnar; Sjøbakk, Torill Eidhammer; Tessem, May-Britt; Moestue, Siver Andreas; Knobel, Heidi; Tandstad, Torgrim; Bertilsson, Helena; Solberg, Arne; Bathen, Tone Frost (Peer reviewed; Journal article, 2020)
      Objective: Simultaneous PET/MRI combines soft-tissue contrast of MRI with high molecular sensitivity of PET in one session. The aim of this prospective study was to evaluate detection rates of recurrent prostate cancer by ...

    • En bloc radical cystectomy: An overview of the technique and oncological results 

      Kjøbli, Eirik; Salvesen, Øyvind Olav; Langørgen, Sverre; Størkersen, Øystein; Wibe, Arne; Arum, Carl-Jørgen (Journal article; Peer reviewed, 2022)
      Objectives To reduce recurrence after radical cystectomy (RC), we developed a technique based on the principles of the circumferential resection margin used during total mesorectal excision for rectal cancer, namely, en ...

    • Multiparametric Prostate MRI in Biopsy-Naïve Men: A Prospective Evaluation of Performance and Biopsy Strategies 

      Krüger-Stokke, Brage; Bertilsson, Helena; Langørgen, Sverre; Sjøbakk, Torill Eidhammer; Bathen, Tone Frost; Selnæs, Kirsten Margrete (Peer reviewed; Journal article, 2021)
      Objectives: This study aims to prospectively estimate the diagnostic performance of multiparametric prostate MRI (mpMRI) and compare the detection rates of prostate cancer using cognitive targeted transrectal ultrasound ...

    • Prostate-Specific Membrane Antigen PET/Magnetic Resonance Imaging for the Planning of Salvage Radiotherapy in Patients with Prostate Cancer with Biochemical Recurrence After Radical Prostatectomy 

      Elschot, Mattijs; Selnæs, Kirsten Margrete; Langørgen, Sverre; Johansen, Håkon; Bertilsson, Helena; Tandstad, Torgrim; Bathen, Tone Frost (Journal article; Peer reviewed, 2019)
      Prostate-specific membrane antigen (PSMA) PET/magnetic resonance (MR) imaging can help distinguish between patients with prostate cancer with locoregional recurrence and those with distant metastases, even at low ...

    • Pseudo-T2 mapping for normalization of T2-weighted prostate MRI 

      Sørland, Kaia Ingerdatter; Sunoqrot, Mohammed R. S.; Sandsmark, Elise; Langørgen, Sverre; Bertilsson, Helena; Trimble, Christopher George; Lin, Gigin; Selnæs, Kirsten Margrete; Goa, Pål Erik; Bathen, Tone Frost; Elschot, Mattijs (Peer reviewed; Journal article, 2022)
      Objective Signal intensity normalization is necessary to reduce heterogeneity in T2-weighted (T2W) magnetic resonance imaging (MRI) for quantitative analysis of multicenter data. AutoRef is an automated dual-reference ...

    • Relative Enhanced Diffusivity in Prostate Cancer: Protocol Optimization and Diagnostic Potential 

      Billdal, Daniel Chen; While, Peter Thomas; Selnæs, Kirsten Margrete; Sunoqrot, Mohammed; Langørgen, Sverre; Bertilsson, Helena; Bathen, Tone Frost; Elschot, Mattijs (Journal article; Peer reviewed, 2019)
      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)
