Automated Patient-level Prostate Cancer Detection with Quantitative Diffusion Magnetic Resonance Imaging
Zhong, Allison Y.; Digma, Leonardino A.; Hussain, Troy; Feng, Christine H.; Conlin, Christopher C.; Tye, Karen; Lui, Asona J.; Andreassen, Maren Marie Sjaastad; Rodríguez-Soto, Ana E.; Karunamuni, Roshan; Kuperman, Joshua; Kane, Christopher J.; Rakow-Penner, Rebecca; Hahn, Michael E.; Dale, Anders M.; Seibert, Tyler M. (Peer reviewed; Journal article, 2023)Background Multiparametric magnetic resonance imaging (mpMRI) improves detection of clinically significant prostate cancer (csPCa), but the subjective Prostate Imaging Reporting and Data System (PI-RADS) system and ... -
Discrimination of Breast Cancer from Healthy Breast Tissue Using a Three-component Diffusion-weighted MRI Model
Andreassen, Maren Marie Sjaastad; Rodriguez-Soto, Ana; Conlin, CC; Vidić, I; Seibert, TM; Wallace, AM; Zare, S; Kuperman, J; Abudu, B; Ahn, GS; Hahn, M; Jerome, Neil Peter; Østlie, Agnes; Bathen, Tone Frost; Ojeda-Fournier, H; Goa, Pål Erik; Rakow-Penner, Rebecca; Dale, AM (Peer reviewed; Journal article, 2020)Purpose: Diffusion-weighted MRI (DW-MRI) is a contrast-free modality that has demonstrated ability to discriminate between predefined benign and malignant breast lesions. However, how well DW-MRI discriminates cancer from ... -
Multimodal Imaging-derived Biomarkers for Early Detection and Personalized Treatment of Breast Cancer
Andreassen, Maren Marie Sjaastad (Doctoral theses at NTNU;2022:304, Doctoral thesis, 2022)Accurate segmentation of cancer from surrounding healthy breast tissues in magnetic resonance imaging (MRI) without intravenous administration of contrast agents, is a question of wide interest. Current standard-of-care ... -
Restriction spectrum imaging with elastic image registration for automated evaluation of response to neoadjuvant therapy in breast cancer
Andreassen, Maren Marie Sjaastad; Loubrie, Stephane; Tong, Michelle W.; Fang, Lauren; Seibert, Tyler; Wallace, Anne M.; Zare, Somaye; Ojeda-Fournier, Haydee; Kuperman, Joshua; Hahn, Michael; Jerome, Neil Peter; Bathen, Tone Frost; Rodríguez-Soto, Ana E.; Dale, Anders; Rakow-Penner, Rebecca (Peer reviewed; Journal article, 2023)Purpose: Dynamic contrast-enhanced MRI (DCE) and apparent diffusion coefficient (ADC) are currently used to evaluate treatment response of breast cancer. The purpose of the current study was to evaluate the three-component ... -
Semi-automatic segmentation from intrinsically-registered 18F-FDG-PET/MRI for treatment response assessment in a breast cancer cohort: comparison to manual DCE-MRI
Andreassen, Maren Marie Sjaastad; Goa, Pål Erik; Sjøbakk, Torill Eidhammer; Hedayati, Roja; Eikesdal, Hans Petter; Deng, Callie; Østlie, Agnes; Lundgren, Steinar; Bathen, Tone Frost; Jerome, Neil Peter (Journal article; Peer reviewed, 2019)Objectives To investigate the reliability of simultaneous positron emission tomography and magnetic resonance imaging (PET/MRI)-derived biomarkers using semi-automated Gaussian mixture model (GMM) segmentation on PET ... -
Tri-Compartmental Restriction Spectrum Imaging Breast Model Distinguishes Malignant Lesions from Benign Lesions and Healthy Tissue on Diffusion-Weighted Imaging
Besser, Alexandra H.; Fang, Lauren K.; Tong, Michelle W.; Andreassen, Maren Marie Sjaastad; Ojeda-Fournier, Haydee; Conlin, Christopher C.; Loubrie, Stéphane; Seibert, Tyler Michael; Hahn, Michael E.; Kuperman, Joshua M.; Wallace, Anne M.; Dale, Anders; Rodríguez-Soto, Ana E.; Rakow-Penner, Rebecca A. (Peer reviewed; Journal article, 2022)Diffusion-weighted MRI (DW-MRI) offers a potential adjunct to dynamic contrast-enhanced MRI to discriminate benign from malignant breast lesions by yielding quantitative information about tissue microstructure. Multi-component ...
