  1. 11. DIXI – a Hybrid Pixel Detector for X-ray Imaging

    Författare :Fredrik Edling; Richard Brenner; Leif Gustafsson; Camilla Rönnqvist; Peter Fischer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; hybrid pixel detector; photon-counting; X-ray; imaging; simulation; Strålningsvetenskap; Radiation biology; Strålningsbiologi;

    Sammanfattning : Medical X-ray imaging is an important tool in diagnostic radiology. The ionising-radiation dose to the patient is justified by the clinical benefit of the examination. Nonetheless, detectors that operate at even lower doses and provide more information to the radiologist are desired. LÄS MER

  3. 12. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Författare :Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Sammanfattning : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. LÄS MER

  4. 13. Translational PET imaging of inflammation

    Författare :Emmi Puuvuori; Olof Eriksson; Tove Grönroos; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET imaging; Nuclear Medicine; Inflammation; Translational Medicine;

    Sammanfattning : Inflammation is our body’s sophisticated defense mechanism against invading pathogens, traumas, and tumors. Repeatable and non-invasive monitoring of inflammation process would open opportunities to improve our knowledge of several diseases and enable assessment of personalized treatments. LÄS MER

  7. 15. Proton Relaxation Properties of a Particulate Iron Oxide MR Contrast Agent in Different Tissue Systems : Implications for Imaging

    Författare :Atle Bjørnerud; Graham A. Wright; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Iron oxide nanoparticles; USPIO; NC100150 Injection; water exchange limited relaxation; MR perfusion imaging.; Onkologi; Oncology; Onkologi; radiologi; Radiology;

    Sammanfattning : Knowledge of the relationship between in vivo contrast agent concentration and magnetic resonance (MR) signal response is an important requirement in contrast enhanced MR imaging in general and in MR based perfusion imaging in particular. This relationship is a complex function of the properties of the contrast agent as well as the structure of the target tissue. LÄS MER
