  1. 1. Quantification of Fat Content and Fatty Acid Composition Using Magnetic Resonance Imaging

    Författare :Pernilla Peterson; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; fat quantification; water fat imaging; chemical shift; skeletal muscle; fat reference; bipolar gradient; fatty acid composition; relaxation;

    Sammanfattning : In obesity and several other disease scenarios, the measurement of fat accumulation in various organs and tissues has become a sought-after technique in clinical diagnostics and research. Especially, quantitative and non-invasive techniques which also provide images of accumulated fat throughout the body would be valuable. LÄS MER

  3. 2. Fat-Referenced MRI : Quantitative MRI for Tissue Characterization and Volume Measurement

    Författare :Thobias Romu; Magnus Borga; Olof Dahlqvist Leinhard; Samir Sharma; Linköpings universitet; []
    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

  4. 3. MRI-based Methods for Quantification of Fat and Fatty Acid Composition. Validation and Applications

    Författare :Lena Trinh; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The interest of in vivo measurements of fat has increased over the years due to the increasing prevalence of obesity and obesity-related conditions such as diabetes, cardiovascular disease, and fatty liver. The relationship between the accumulation of adipose tissue within the different depots and organs of the body, and the risk of developing numerous diseases, has been investigated and established.

  5. 4. Regulation of energy balance in Caenorhabditis elegans 

    Författare :Ming Sheng; Simon Tuck; Lars Nilsson; Carina Holmberg-Still; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C.elegans; fat metabolism; S6 Kinase; FT-IR; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Sammanfattning : Obesity is a medical condition in which excess body fat has been accumulated. It is most commonly caused by imbalance between energy intake and energy expenditure (lack of physical activity and lower metabolic rate, etc.). LÄS MER

  7. 5. Validation of Phase Contrast Flow Quantification and Relaxometry for Cardiovascular Magnetic Resonance Imaging

    Författare :Sebastian Bidhult; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :;

    Sammanfattning : Quantitative imaging, where every pixel of an image represents a physical quantity (e.g. timeor velocity) is being increasingly used in the field of diagnostic radiology and has potential toenhance medical diagnosis. LÄS MER
