  1. 16. 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. 17. Anterior shoulder dislocation : Aspects of alternative methods of treatment and MR imaging

    Författare :Göran Wintzell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Shoulder; traumatic primary dislocation; arthroscopic lavage; non-operative regime; Indirect MR arthrography; apprehension position; ABER position; Bankart operation; Kirurgi; Surgery; Kirurgi; Orthopaedics; ortopedi;

    Sammanfattning : Sixty patients (16-30 years) with traumatic primary anterior shoulder dislocation were allocated to arthroscopic lavage or non-operative treatment. The arthroscopic lavage group had a lower recurrence rate, better functional outcome and anterior stability after one year. LÄS MER

  4. 18. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy

    Författare :Mary Adjeiwaah; Tufve Nyholm; Anders Garpebring; Joakim Jonsson; Sofie Ceberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; MRI; radiotherapy; RT; geometric distortions; magnetic susceptibility; B0 maps; quality assurance; radiofysik; radiation physics;

    Sammanfattning : The use of Magnetic Resonance Imaging (MRI) in the radiotherapy (RT) treatment planning workflow is increasing. MRI offers superior soft-tissue contrast compared to Computed Tomography (CT) and therefore improves the accuracy in target volume definitions. LÄS MER

  5. 19. Mangafodipir trisodium (MnDPDP)-enhanced magnetic resonance imaging of the liver and pancreas

    Författare :Chen Wang; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Liver; pancreas; neoplasms; metastases; endocrine tumor; MR imaging; contrast medium; mangafodipir trisodium; MnDPDP; manganese; Onkologi; Oncology; Onkologi; diagnostisk radiologi; Diagnostic Radiology;

    Sammanfattning : Contrast-enhanced magnetic resonance imaging (MRI) of the liver and pancreas is frequently performed to improve the sensitivity and specificity of lesion detection in these organs. The concept of using tissue-specific contrast media is to selectively enhance the normal parenchyma, but not lesions, so that the contrast between tumorous and normal tissue is increased, and lesion detectability improved.

  7. 20. Optimisation in strategies in diffusion tensor MR imaging

    Författare :Stefan Skare; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diffusion tensor; magnetic resonance imaging; optimisation; artefacts;

    Sammanfattning : With diffusion MR imaging, the Brownian motion (or self-diffusion) of water molecules is measured. In the corresponding ADC (Apparent Diffusion Coefficient) image, each image element (voxel) represents the average diffusion. In MRI, the diffusion is measured with diffusion gradients along certain directions in space. LÄS MER
