2.5D and 3D segmentation of brain metastases with deep learning on multinational MRI data
Ottesen, Jon André; Yi, Darvin; Tong, Elizabeth; Iv, Michael; Latysheva, Anna; Saxhaug, Cathrine; Jacobsen, Kari Dolven; Helland, Åslaug; Emblem, Kyrre E; Rubin, Daniel L.; Bjørnerud, Atle; Zaharchuk, Greg; Grøvik, Endre (Peer reviewed; Journal article, 2023)Introduction: Management of patients with brain metastases is often based on manual lesion detection and segmentation by an expert reader. This is a time- and labor-intensive process, and to that end, this work proposes ... -
Automatic segmentation of human knee anatomy by a convolutional neural network applying a 3D MRI protocol
Kulseng, Carl Petter Skaar; Nainamalai, Varatharajan; Grøvik, Endre; Geitung, Jonn Terje; Årøen, Asbjørn; Gjesdal, Kjell Inge (Peer reviewed; Journal article, 2023)Background: To study deep learning segmentation of knee anatomy with 13 anatomical classes by using a magnetic resonance (MR) protocol of four three-dimensional (3D) pulse sequences, and evaluate possible clinical usefulness. ... -
Comparison of Intravoxel incoherent motion imaging and multiecho dynamic contrast-based MRI in rectal cancer
Bakke, Kine Mari; Grøvik, Endre; Meltzer, Sebastian; Negård, Anne; Holmedal, Stein Harald; Mikalsen, Lars Tore G; Lyckander, Lars Gustav; Ree, Anne Hansen; Gjesdal, Kjell-Inge; Redalen, Kathrine; Bjørnerud, Atle (Journal article; Peer reviewed, 2019)Background Dynamic contrast‐based MRI and intravoxel incoherent motion imaging (IVIM) MRI are both methods showing promise as diagnostic and prognostic tools in rectal cancer. Both methods aim at measuring perfusion‐related ... -
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, ... -
Sex differences and tumor blood flow from dynamic susceptibility contrast MRI are associated with treatment response after chemoradiation and long-term survival in rectal cancer
Bakke, Kine Mari; Meltzer, Sebastian; Grøvik, Endre; Negård, Anne; Holmedal, Stein Harald; Gjesdal, Kjell-Inge; Bjørnerud, Atle; Ree, Anne Hansen; Redalen, Kathrine (Peer reviewed; Journal article, 2020)Sex differences, tumor vascularity, and blood flow seen on multiecho dynamic contrast–based MRI scans enabled prediction of treatment response and overall survival in patients with rectal cancer. Background: MRI is the ...
