  2. 1. Pushing diffusion MRI towards new dimensions

    Author : Joao Martins; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; MRI; diffusion; relaxation; multidimensional diffusion MRI; relaxation-diffusion correlations; Laplace NMR; porous media; tissue microstructure; heterogeneity; anisotropy;

    Abstract : Diffusion-MRI techniques allow the non-invasive investigation of microstructural changes in living tissues. However, a detailed interpretation of the data is complicated by the fact that multiple microscopic environments with varying diffusion properties all contribute to the measured signal. READ MORE

  4. 2. Probing brain microstructure with multidimensional diffusion MRI: Encoding, interpretation, and the role of exchange

    Author : Björn Lampinen; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Diffusion; Human; Brain; Microstructure; Fysicumarkivet A:2021:Lampinen;

    Abstract : Diffusion MRI (dMRI) is a non-invasive probe of human brain microstructure. It is a long-standing promise to use dMRI for ‘in vivo histology’ and estimate tissue quantities. However, this faces several challenges. First, the microstructure models used for dMRI data are based on assumptions that may cause erroneous interpretations. READ MORE
