  1. 6. Magnetic Resonance Imaging of Human Brown Adipose Tissue : Methodological Development and Application

    Författare :Elin Lundström; Joel Kullberg; Håkan Ahlström; Lars Johansson; Robin Strand; Sven Månsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brown adipose tissue; Magnetic resonance imaging; Positron emission tomography; Image segmentation; Glucose metabolism;

    Sammanfattning : Brown adipose tissue (BAT) is a thermogenic organ with the main human depot located in the cervical-supraclavicular (sBAT) region. BAT is proposed as a potential therapeutic target for obesity and diabetes. LÄS MER

  3. 7. Quantitative magnetic resonance in diffuse liver and neurological disease

    Författare :Olof Dahlqvist Leinhard; Linköpings universitet; []
    Nyckelord :Mapping--methods; Choline--analysis; Liver diseases--diagnosis; Magnetic resonance imaging--methods; Magnetic resonance spectroscopy--methods; Multiple sclerosis--diagnosis; Multiple sclerosis--metabolism; Nerve fibers; myelinated--metabolism; MEDICINE; MEDICIN;

    Sammanfattning : Magnetic resonance (MR) has become one of the most important diagnostic tools in modern medicine. It provides superior soft tissue contrast compared to other imaging modalities, it is extremely flexible as it can be used to image all parts of the body, and it is considered to be safe for patients.

  4. 8. Assessment of Body Composition Using Magnetic Resonance Imaging

    Författare :Joel Kullberg; Hans Frimmel; Tomas Gustavsson; Uppsala universitet; []
    Nyckelord :Bildanalys; Magnetic Resonance Imaging; Digital Image Processing; Segmentation; Morphology; Body Composition; Whole Body Imaging; Subcutaneous Adipose Tissue; Visceral Adipose Tissue; Anthropometry; Bildanalys;

    Sammanfattning : Methods for assessment of body composition allow studies of the complex relationships between body composition and the wellbeing of humans. The amount and distribution of adipose tissue is of great importance in these studies. LÄS MER

  5. 9. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy

    Författare :Mary Adjeiwaah; Tufve Nyholm; Rob HN Tijssen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic resonance imaging; Radiotherapy; geometric distortions; patient-induced susceptibilities MR-only; radiofysik; radiation physics;

    Sammanfattning : Magnetic resonance imaging (MRI) utilizes the magnetic properties of tissues to generate image-forming signals. MRI has exquisite soft-tissue contrast and since tumors are mainly soft-tissues, it offers improved delineation of the target volume and nearby organs at risk. LÄS MER

  7. 10. Evaluation of Intracranial Arteriovenous Malformations with Magnetic Resonance Imaging

    Författare :Maria Correia de Verdier; Johan Wikström; Elisabeth Ronne-Engström; Ljubisa Borota; Johan Wassélius; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arteriovenous malformation; brain; proton-radiation therapy; magnetic resonance imaging; phase-contrast MRI; Radiology; Radiologi;

    Sammanfattning : Intracranial arteriovenous malformations (AVMs) are characterized by feeding arteries, a tangle of abnormal vessels (nidus) and draining veins. Radiological evaluation methods are used in diagnosing AVMs, treatment planning, post-treatment evaluation and monitoring stability. LÄS MER
