  2. 1. Simulation supported training in oral radiology : methods and impact on interpretative skill

    Author : Tore Nilsson; Jan Ahlqvist; Martin Rydmark; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virtual reality; simulation; simulator; radiology; radiography; learning; skill acquisition; visual-spatial ability; parallax; Radiology; Radiologi; odontologi; Odontology;

    Abstract : Simulation is an important tool when training is hazardous, time consuming, or expensive. Simulation can also be used to enhance reality by adding features normally not available in the real world. READ MORE

  4. 2. Imaging the tumor microenvironment : the dynamics and modification of hypoxia

    Author : Anna Ljungkvist; Peggy L. Olive; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; tumor microenvironment; double hypoxic marker method; proliferation; hypoxia; hypoxic half-life; Radiologisk forskning; Radiological research; Radiologisk forskning; diagnostisk radiologi; Diagnostic Radiology;

    Abstract : The tumor vasculature is poor and heterogeneous which may result in inadequate oxygenation and changed energy status. In addition the balance between cell proliferation and the rate of cell death is disturbed, which results in tumor growth. READ MORE

  5. 3. Prostate Cancer Diagnosis : experimental and Clinical Studies With HRMAS NMR Spectroscopy

    Author : Katarina Stenman; Katrine Åhlström-Riklund; Anders Bergh; Peter Lundberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; PCa; HRMAS NMR; MRSI; metabolomics; Gleason score; citrate; inositol; choline; Krebs cycle; PUFA; omega-6; omega-3; Diagnostic radiology; Diagnostisk radiologi; Radiology; radiologi;

    Abstract : A few abnormal cells found in a small piece of prostate tissue are most consequential for a man’s future. The prevalence of prostate cancer (PCa) is increasing globally. READ MORE

  6. 4. Quantifying image quality in diagnostic radiology using simulation of the imaging system and model observers

    Author : Gustaf Ullman; Michael Sandborg; Gudrun Alm Carlsson; Nicolas Pallikarakis; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; radiation physics; image quality; optimisation; effective dose; chest radiography; Radiological physics; Radiofysik;

    Abstract : Accurate measures of both clinical image quality and patient radiation risk are needed for successful optimisation of medical imaging with ionising radiation. Optimisation in diagnostic radiology means finding the image acquisition technique that maximises the perceived information content and minimises the radiation risk or keeps it at a reasonably low level.

  7. 5. Quantification of Arterial Wall with MRI and Image Processing

    Author : Mari Hänni; Torbjörn Andersson; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
