  2. 11. Polycystic ovary syndrome - morphologic and dynamic evaluation by magnetic resonance imaging

    Author : Henrik Leonhardt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycystic ovary syndrome; PCOS; magnetic resonance imaging; MRI; ultrasonography; three-dimensional imaging; adrenal hyperplasia; body composition; uterine morphology; uterine peristalsis; ovarian morphology; ovarian perfusion; antral follicle count; AMH; diagnostic accuracy;

    Abstract : Polycystic ovary syndrome (PCOS) is a complex endocrine disorder, affecting up to 15% of women of reproductive age. The syndrome is characterized by oligo-anovulation, hyperandrogenism and polycystic ovaries. What constitutes the best definition of PCOS is still a matter of debate. READ MORE

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

    Author : Mary Adjeiwaah; Tufve Nyholm; Rob HN Tijssen; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 13. Assessment of Body Composition Using Magnetic Resonance Imaging

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

    Abstract : 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. READ MORE

  6. 14. Applications of statistical methods in quantitative magnetic resonance imaging

    Author : Patrik Brynolfsson; Anders Garpebring; Tufve Nyholm; Eirik Malinen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative imaging; tumor imaging; dynamic contrast-enhanced MRI; diffusion weighted MRI; texture analysis; radiofysik; radiation physics;

    Abstract : Magnetic resonance imaging, MRI, offers a vast range of imaging methods that can be employed in the characterization of tumors. MRI is generally used in a qualitative way, where radiologists interpret the images for e.g. diagnosis, follow ups, or assessment of treatment response. READ MORE

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

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

    Abstract : 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. READ MORE
