  1. 21. Targeted radiotherapy in metastatic neuroendocrine tumours: clinical and experimental studies

    Författare :Anna-Karin Elf; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuroendocrine tumour; peptide receptor radionuclide therapy; somatostatin receptor 2 expression; radiosensitization; radioembolization; diffusion weighted imaging;

    Sammanfattning : ABSTRACT Neuroendocrine tumours (NET) often present at a metastatic stage, which diminishes the possibility for curative surgery. Peptide receptor radiotherapy (PRRT) with 177Lu-DOTATATE targets somatostatin receptors, which are overexpressed on NET cells. PRRT results in symptom relief and often tumour control of NETs, but rarely cure. LÄS MER

    Sammanfattning : Our brain, perhaps the most sophisticated and mysterious part of the human body, to some extent, determines who we are. However, it’s a vulnerable organ. When subjected to an impact, such as a traffic accident or sport, it may lead to traumatic brain injury (TBI) which can have devastating effects for those who suffer the injury. LÄS MER

  4. 23. Hyperpolarized 3He-diffusion MRI in evaluation of lung structure in emphysema. Validation and development of the method

    Författare :Sandra Diaz; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Helium; Hyperpolarized; MRI; ADC; Emphysema;

    Sammanfattning : Abstract COPD is a major cause of chronic morbidity and mortality throughout the world. It is a preventable and treatable disease. Smoking is the most commonly encountered risk factor for COPD and the habit now unfortunately starts at earlier ages than before. LÄS MER

  5. 24. Magnetic resonance imaging and advanced imaging assessment of the growth plate in the adolescent and young adult

    Författare :Ola Kvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The growth plate is a cartilaginous structure located between the metaphysis and epiphysis in long bones. It is the centre for longitudinal growth. Longitudinal growth has a biphasic pattern with a peak during foetal and early postnatal life and another peak during puberty. LÄS MER

  7. 25. Diffusion-encoded MRI for assessment of structure and microcirculation : Aspects of q-space imaging and improved IVIM modelling

    Författare :Anna Scherman Rydhög; Lund Medicinsk strålningsfysik; []
    Nyckelord :;

    Sammanfattning : Diffusion and perfusion MRI are valuable methods for investigating the microstructure and viability of tissue. One pure diffusion study was included in this thesis, with the purpose of studying microstructure and carrying out size estimations with the q-space diffusion imaging method. LÄS MER
