  1. 21. Magnetic resonance imaging in the evaluation of chronic Achilles tendinosis

    Författare :Anna Gärdin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aim of the thesis was to evaluate magnetic resonance imaging (MRI) as an outcome in the evaluation of treatment in mid-portion Achilles tendinosis. Conventional MRI sequences, dynamic contrast enhanced MRI and measurement of transversal relaxation time, using an ultrashort time to echo sequence, has been evaluated. LÄS MER

  3. 22. Very preterm birth and fetal growth restriction in adolescence - Cardiovascular and renal aspects

    Författare :Jonas Liefke; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preterm and low birth weight; Fetal growth restriction; Magnetic resonance imaging MRI ; Cardiac function; Preterm birth; Adolescence; Kidney function; Kidney anatomy histology; Cardiovascular biomarkers; Arterial stiffness; Ambulatory blood pressure measurement; Biochemical makers;

    Sammanfattning : This thesis applied magnetic resonance imaging (MRI) to investigate to what extent very preterm birth due to early onset fetal growth restriction (FGR) impacts the cardiovascular system and kidneys in adolescence. The thesis further investigated whether FGR exacerbates the organ-specific effects of very preterm birth. LÄS MER

  4. 23. The value of new sonographic modalities, demographic, biometric and proliferative variables for the risk prediction in endometrial cancer

    Författare :Rasmus W Green; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Endometrial cancer is the sixth most common type of cancer among women worldwide and constitutes 4.8% of all cancer in women. The incidence is highest in highincome countries, given how age and obesity are the two most important risk factors. The majority of cases present at an early stage, with a favourable prognosis.

  5. 24. Preoperative MRI and PET in suspected low-grade gliomas : Radiological, neuropathological and clinical intersections

    Författare :Anna Falk Delgado; Elna-Marie Larsson; Anja Smits; Jens Sörensen; John Hald; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low-grade glioma; MRI; PET; FA; MD; Perfusion; Diffusion; Neuropathology; Oligodendroglioma; Astrocytoma; PET; tractography; DTI; DTT; Radiologi; Radiology;

    Sammanfattning : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. LÄS MER

  7. 25. Vascular ultrasound for the assessment of carotid atherosclerosis

    Författare :Davide Vanoli; Per Lindqvist; Christine Kremer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ultrasound; Plaque; IMT; Atherosclerosis; CEUS; Carotid vessels; cardiovascular disease; hjärt- och kärlforskning;

    Sammanfattning : Background: Atherosclerotic cardiovascular disease (CVD) is a common cause for mortality globally, and is expected to remain the single leading cause of death as the global population ages and as life expectancy increases.Cardiovascular screening models have been developed, and continue to be developed, to identify individuals at high-risk of CVD.
