  1. 6. Quantitative Magnetic Resonance Imaging of the Brain : Applications for Tissue Segmentation and Multiple Sclerosis

    Författare :Janne West; Peter Lundberg; Anne-Marie Landtblom; Marcel Jan Bertus Warntjes; Örjan Smedby; Olof Dahlqvist Leinhard; Per Thunberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Magnetic resonance imaging (MRI) is a sensitive technique for assessing white matter (WM) lesions in multiple sclerosis (MS), but there is a low correlation between MRI findings and clinical disability. Because of this, other pathological changes are of interest, including changes in normal appearing white matter (NAWM) and diffusely abnormal white matter (DAWM). LÄS MER

  3. 7. Diffusion MRI of Small Ischemic Brain Lesions: Technical aspects, clinical experiences and diagnostic criteria

    Författare :Bo Geijer; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; Metastasis; ADC; b; Infarct; MRI; Ischemia; Diffusion-Weighted; Diffusion; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Purpose: To compare the visualization of small ischemic brain lesions using diffusion using diffusion-weighted (DW) MRI and conventional imaging, with special regard to diagnostic efficiency. Imaging features of lesions of different ages, diagnostic limitations and technical principles were also investigated. LÄS MER

  4. 8. Auditory event-related potentials and cognitive outcome after very preterm birth

    Författare :Holger Hövel; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preterm; Event-related potentials; Mismatch negativity; Magnetic resonance imaging; developmental outcome;

    Sammanfattning : Children born before 32 gestational weeks have a high incidence of neuropsychological deficits. The structural and functional correlates of such impairments in preterm infants are incompletely understood, and early diagnostic tools are needed, but still lacking. LÄS MER
