  1. 21. 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

  3. 22. Optimized MRI methods for simplified oncological imaging in pancreas and liver

    Författare :Nikolaos Kartalis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Recent technological advances within the fields of Abdominal Imaging have revolutionised oncological imaging. In the investigation of the solid organs in the upper abdomen, extensive examinations are used in order to obtain accurate information. LÄS MER

  4. 23. Monitoring the effect of anti-cancer treatment in uro-oncological malignancies with molecular imaging

    Författare :Jacob Farnebo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In the last decade, new therapies have changed the management of patients with metastatic renal cell carcinoma (mRCC) and metastatic castration resistant prostate cancer (mCRPC). Although new therapies have improved survival, drug response varies widely with some patients not responding to treatment. LÄS MER

  5. 24. Placental Function : An Epidemiological and Magnetic Resonance Study

    Författare :Sara Sohlberg; Anna-Karin Wikstrom; Matts Olovsson; Ajlana Mulic-Lutvica; Johan Wikström; Karel Marsal; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; body height; body mass index; early preeclampsia; late preeclampsia; magnetic resonance imaging; placenta; perfusion; IVIM; risk factors; energy metabolism; magnetic resonance spectroscopy; 31P-MRS; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Placental function is central for normal pregnancy and in many of the major pregnancy disorders. We used magnetic resonance imaging techniques to investigate placental function in normal pregnancy, in early and late preeclampsia and in intrauterine growth restriction. 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
