  1. 21. Quantification of Arterial Wall with MRI and Image Processing

    Författare :Mari Hänni; Torbjörn Andersson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; image processing; Magnetic resonance imaging; animal model; arterial wall; Radiologisk forskning; atherosclerosis; Radiological research; Radiologisk forskning; Diagnostisk radiologi; Diagnostic Radiology;

    Sammanfattning : Quantification of atherosclerosis in vivo in animal models is of great importance when treatments against atherosclerosis are evaluated. In the studies presented in this thesis a non-invasive method combining MRI and image processing is evaluated. LÄS MER

  3. 22. PET imaging of beta-cell mass

    Författare :Pierre Cheung; Olof Eriksson; Weibo Cai; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET imaging; diabetes; beta-cell mass; affibody; SC-islets; Medicinal Chemistry; Läkemedelskemi;

    Sammanfattning : A hallmark of diabetes is the progressive loss of the beta-cell mass (BCM) and function. Most of the diagnostic methods for diabetes are mostly reflective of the beta-cell function, whereas current methodologies for studying the beta-cell mass are limited to post-mortem biopsies or highly invasive methods.

  4. 23. Pituitary Tumors - Epidemiology and the Diagnostic Value of 68Ga-DOTATOC PET

    Författare :Axel Tjörnstrand; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; Pituitary neuroendocrine tumor; pituitary tumor; somatostatin receptor imaging; gallium68; 68Ga; SSTR; SSTR-PET;

    Sammanfattning : Pituitary neuroendocrine tumors (PitNETs) are considered common in the general population. However benign in most cases, these tumors can evoke dramatic morbidity in patients with aggressive tumor growth and/or excess hormone secretion. LÄS MER

  5. 24. Image Processing and Analysis Methods for Biomedical Applications

    Författare :Eva Breznik; Robin Strand; Filip Malmberg; Joel Kullberg; Håkan Ahlström; Alejandro Frangi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple comparisons; image segmentation; image retrieval; deep learning; medical image analysis; magnetic resonance imaging; whole-body imaging; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : With new technologies and developments medical images can be acquired more quickly and at a larger scale than ever before. However, increased amount of data induces an overhead in the human labour needed for its inspection and analysis. LÄS MER

  7. 25. Quantitative magnetic resonance in diffuse liver and neurological disease

    Författare :Olof Dahlqvist Leinhard; Linköpings universitet; []
    Nyckelord :Mapping--methods; Choline--analysis; Liver diseases--diagnosis; Magnetic resonance imaging--methods; Magnetic resonance spectroscopy--methods; Multiple sclerosis--diagnosis; Multiple sclerosis--metabolism; Nerve fibers; myelinated--metabolism; MEDICINE; MEDICIN;

    Sammanfattning : Magnetic resonance (MR) has become one of the most important diagnostic tools in modern medicine. It provides superior soft tissue contrast compared to other imaging modalities, it is extremely flexible as it can be used to image all parts of the body, and it is considered to be safe for patients.
