  1. 1. Fat-Referenced MRI Quanitaive MRI for Tissue Characterizaion and Volume Measurement

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Thobias Romu; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; water-fat separation; quantitative MRI;

    Sammanfattning : The amount and distribution of adipose and lean tissues has been shown to be predictive of mortality and morbidity in metabolic disease. Traditionally these risks are assessed by anthropometric measurements based on weight, length, girths or the body mass index (BMI). LÄS MER

  3. 2. Pushing diffusion MRI towards new dimensions

    Detta är en avhandling från Lund University, Faculty of Science, Department of Chemistry, Division of Physical Chemistry

    Författare :Joao Martins; Lund University.; Lunds universitet.; [2020-01]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR; MRI; diffusion; relaxation; multidimensional diffusion MRI; relaxation-diffusion correlations; Laplace NMR; porous media; tissue microstructure; heterogeneity; anisotropy;

    Sammanfattning : 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. LÄS MER

  5. 4. Quantitative Evaluation of Contrast Agent Dynamics in Liver MRI

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Nils Dahlström; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liver; spleen; hepatobiliary system; liver function; MRI; DCE-MRI; Gd-EOBDTPA; Gd-BOPTA; pharmacokinetic; hepatocyte; relaxivity.; MEDICINE; MEDICIN;

    Sammanfattning : The studies presented here evaluate the biliary, parenchymal and vascular enhancement effects of two T1-shortening liver-specific contrast agents, Gd-BOPTA and Gd-EOB-DTPA, in Magnetic Resonance Imaging (MRI) of healthy subjects and of patients.Ten healthy volunteers were examined with both contrast agents in a 1.

  7. 5. MRI assessment of haemophilic arthropathy

    Detta är en avhandling från Institutionen för kliniska vetenskaper, Lunds universitet

    Författare :Björn Lundin; Lund University.; Lunds universitet.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; tomografi; medicinsk instrumentering; medical instrumentation; tomography; radiology; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; Arthropathy; Factor VIII; Factor IX; MRI; Haemophilia; Klinisk fysiologi;

    Sammanfattning : Haemophilia is a recessive genetic bleeding disorder in which coagulation time is prolonged due to the absence or malfunction of either of the serum proteins Factor VIII or IX. Joint destruction following repeated haemarthroses is the main cause of morbidity in haemophiliacs, and such arthropathy can be prevented or postponed by implementing prophylactic therapy with factor concentrate at an early age.
