  1. 1. Applications of diffusion MRI: Tensor-valued encoding, time-dependent diffusion, and histological validation

    Author : Jan Brabec; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diffusion MRI; meningioma; glioma; brain tumors; intracranial tumors; undulations; restricted diffusion; time dependence; spherical b-tensor encoding; linear b-tensor encoding; histogram analysis; anisotropic kurtosis; isotropic kurtosis; hyperintensity; conspicuity; white matter; detection; diffusion spectrum; consistency; type; grade; axon diameter; axonal trajectories; Fysicumarkivet A:2022:Brabec;

    Abstract : Diffusion MRI (dMRI) sensitizes the MR signal to the diffusion of water molecules at the microscopic level and thereby non-invasively probes tissue microstructure. This is relevant when determining biological properties of tissues, for example, cancer type and its malignancy. READ MORE

    Abstract : BackgroundGastrointestinal (GI) symptoms are commonly reported in a normal population. Mostly, the symptoms are of benign cause but occasionally the symptoms can be signs of a more harmful disease. In general, it is difficult to distinguish whether the reported symptoms are caused by a benign (functional) or organic (i.e. READ MORE

  5. 5. High-grade spondylolisthesis in young patients : Long-term results of in situ fusion
