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 ... -

Support vector machine for breast cancer classification using diffusion-weighted MRI histogram features: Preliminary study.
Vidic, Igor; Egnell, Liv; Jerome, Neil Peter; Teruel, Jose Ramon; Sjøbakk, Torill Eidhammer; Østlie, Agnes; Fjøsne, Hans Erikssønn; Bathen, Tone Frost; Goa, Pål Erik (Journal article, 2017)Background Diffusion-weighted MRI (DWI) is currently one of the fastest developing MRI-based techniques in oncology. Histogram properties from model fitting of DWI are useful features for differentiation of lesions, and ...
