  1. 6. Clinical Applications of Synthetic MRI of the Brain

    Författare :Ida Blystad; Elna-Marie Larsson; Peter Lundberg; Marcel Warntjes; Örjan Smedby; Anne-Marie Landtblom; John Hald; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Magnetic Resonance Imaging (MRI) has a high soft-tissue contrast with a high sensitivity for detecting pathological changes in the brain. Conventional MRI is a time-consuming method with multiple scans that relies on the visual assessment of the neuroradiologist. LÄS MER

  3. 7. Drugs and polymers in dissolving solid dispersions : NMR imaging and spectroscopy

    Författare :Carina Dahlberg; István Furó; Anna Millqvist-Fureby; Michael Schuleit; Jadwiga Tritt-Goc; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical chemistry; Fysikalisk kemi; Surface and colloid chemistry; Yt- och kolloidkemi; PHARMACY; FARMACI;

    Sammanfattning : The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioavailability of the drug.

  4. 8. Quantitative evaluation of liver function using gadoxetic acid-enhanced MRI

    Författare :Qiang Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Before liver resection, a reliable and accurate assessment of the liver function is essential to ensure a safe surgery and avoid unfavorable complications such as post-hepatectomy liver failure (PHLF). Gadoxetic acid enhanced magnetic resonance imaging (MRI) is a routinely used imaging modality for tumor detection and characterization. LÄS MER

  5. 9. MRI in multiple sclerosis : early detection, cortical lesions and gadolinium retention

    Författare :Yngve Forslin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Multiple sclerosis (MS) is a common neuroinflammatory and -degenerative disease. Magnetic Resonance Imaging (MRI) facilitates the diagnosis of MS, providing means to initiate early treatment and improving the long-term outcome. LÄS MER

  7. 10. Experimental studies of ion transport in cementitious materials under partially saturated conditions

    Författare :Nilla Olsson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :Cement; Bruk; Betong; Jontransport; Fukttransport; Sorptionsisoterm; Tillsatsmaterial; Kiselstoft; Masugnsslagg; Ciment; Mortier; Béton; Transport ionique; Transport d humidité; Sorption de vapeur d eau; Additions minérales; Fumée de silice; Laitier de haut fourneau granulé moulu; Cement; Mortar; Concrete; Ion transport; moisture transport; Water vapor sorption; Supplementary cementitious materials SCMs ; Silica fume; Ground granulated blast furnace slag;

    Sammanfattning : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. LÄS MER
