Diffusivity in breast malignancies analyzed for b > 1000 s/mm2 at 1 mm in‐plane resolutions: Insight from Gaussian and non‐Gaussian behaviors
Sign Up to like & getrecommendations! Published in 2020 at "Journal of Magnetic Resonance Imaging"
DOI: 10.1002/jmri.27489
Abstract: Diffusion‐weighted imaging (DWI) can improve breast cancer characterizations, but often suffers from low image quality –particularly at informative b > 1000 s/mm2 values. The aim of this study was to evaluate multishot approaches characterizing Gaussian and non‐Gaussian diffusivities… read more here.
