  1. 1. Diffusion tensor magnetic resonance imaging of the brain : Tractography analysis with application in healthy individuals and patients

    Författare :Johanna Mårtensson; Elna-Marie Larsson; Jimmy Lätt; Danielle van Westen; Tim Dyrby; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; Diffusion Tensor Imaging; Tractography; white matter tracts; Radiology; Radiologi;

    Sammanfattning : In study 1, thirty-eight healthy controls were used for optimization of the method. Fifteen patients with progressive supranuclear palsy and an equal number of age-matched healthy controls underwent diffusion tensor MRI and were then investigated and compared groupwise. LÄS MER

  2. 2. Magnetic resonance imaging and diffusion tensor imaging after brachial plexus injury and repair : Experimental and clinical study

    Författare :Grainne Bourke; Mikael Wiberg; Lev N. Novikov; Lars Dahlin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brachial Plexus; Magnetic Resonance Imaging; Neonatal; Diffusion Tensor Imaging;

    Sammanfattning : Brachial plexus injuries (BPI) cause permanent upper limb paralysis and serious disability in adults and children. Timely identification of the severity of nerve injury and early appreciation of the inane potential for recovery would revolutionise management. LÄS MER

  3. 3. Nuclear Magnetic Resonance for Diffusion Imaging Development and evaluation of spin-echo-based pulse sequences for in vivo studies of water self-diffusion

    Författare :Sara Brockstedt; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perfusion fraction; electrocardiographic triggering; segmented EPI SEPI ; echo-planar imaging EPI ; fast spin-echo FSE ; spin-echo SE ; navigator echoes; phase corrections; diffusion; Magnetic resonance; MRI; ischaemic stroke; Medicine human and vertebrates ; Medicin människa och djur ;

    Sammanfattning : The interest in diffusion imaging with nuclear magnetic resonance techniques has increased during the last few years. The main reason is the possibility of early diagnosis of acute ischaemic stroke, at a time when conventional MR techniques and computerised tomography fail. LÄS MER

  4. 4. Applications of statistical methods in quantitative magnetic resonance imaging

    Författare :Patrik Brynolfsson; Anders Garpebring; Tufve Nyholm; Eirik Malinen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative imaging; tumor imaging; dynamic contrast-enhanced MRI; diffusion weighted MRI; texture analysis; radiofysik; radiation physics;

    Sammanfattning : Magnetic resonance imaging, MRI, offers a vast range of imaging methods that can be employed in the characterization of tumors. MRI is generally used in a qualitative way, where radiologists interpret the images for e.g. diagnosis, follow ups, or assessment of treatment response. LÄS MER

  5. 5. Differentiation of Central Nervous System Tumors: Multiparametric magnetic resonance imaging with histological, genetic, and prognostic correlations

    Författare :Faris Durmo; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; Magnetic resonance imaging MRI ; Metastases; Amide proton transfer imaging; diffusion weighted imaging; perfusion weighted imaging; Diagnostics; TUMORS;
