  1. 11. 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

    Författare :Fei Ye; Mamounm Muhammed; Joydeep Dutta; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nanostructured materials have attracted a broad interest for applications in scientific and engineering fields due to their extraordinary properties stemming from the nanoscale dimensions. This dissertation presents the development of nanomaterials used for different applications, namely biomedicine and dye lasing. LÄS MER

  4. 13. Dynamic magnetic resonance imaging of the breast : imaging features for diagnosis and prognosis of breast cancer

    Författare :Botond K Szabo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Breast neoplasm; magnetic resonance imaging; prognostic factors; survival analysis; image segmentation; artificial neural networks;

    Sammanfattning : The general aim of the present thesis was to identify and study dynamic contrast-enhanced magnetic resonance imaging (CE-MRI) features that contribute to the diagnosis and may help in predicting prognosis in breast cancer. Study I studied the kinetic and morphological MR features and their diagnostic power were studied in a total of 92 women with 109 histopathologically verified breast lesions. LÄS MER

  5. 14. Radiological evaluation of bone marrow transplanted multipel myeloma patients

    Författare :Brita Ågren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis concerns radiological evaluation of bone marrow transplanted multiple myeloma (MM) patients. The diagnostic radiological modalities evaluated are: conventional radiography (RG); bone scintigraphy (BS); bone marrow scintigraphy (MS); magnetic resonance imaging (MRI). The 242 included examinations are: 91 RG, 85BS, 33 MS and 33 MRI. LÄS MER

  7. 15. Radiomics in cancer prognosis : applications and limitations of quantitative texture analysis

    Författare :Yi-Hua Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Medical imaging has become an integral part of clinical diagnostics since the discovery of X- rays at the end of the 19th century. Recent advances in computing power have opened up the possibility to extract quantitative data from medical images beyond what is visible to the human eye, so-called radiomics. LÄS MER
