  1. 11. Functional Magnetic Resonance Imaging for Clinical Diagnosis : Exploring and Improving the Examination Chain

    Författare :Mattias Ragnehed; Peter Lundberg; Maria Engström; Örjan Smedby; Peter Fransson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Radiologi;

    Sammanfattning : Functional Magnetic Resonance Imaging (fMRI) is a relatively new imaging technique, first reported in 1992, which enables mapping of brain functions with high spatial resolution. Functionally active areas are distinguished by a small signal increase mediated by changes in local blood oxygenation in response to neural activity. LÄS MER

  3. 12. Supporting Quantitative Visual Analysis in Medicine and Biology in the Presence of Data Uncertainty

    Författare :Khoa Tan Nguyen; Timo Ropinski; Anders Ynnerman; Anna Vilanova Bartroli; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The advents of technologies have led to tremendous increases in the diversity and size of the available data. In the field of medicine, the advancements in medical imaging technologies have dramatically improved the quality of the acquired data, such as a higher resolution and higher signal-to-noise ratio.

  4. 13. The Non-Invasive Brain Biopsy : Implementation and Application of Quantitative Magnetic Resonance Spectroscopy on Healthy and Diseased Human Brain

    Författare :Anders Tisell; Peter Lundberg; Marcel Warntjes; Anne-Marie Landtblom; Örjan Smedby; Jan Weis; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Introduction: In this thesis, one of the major objectives was to implement a method for (absolute) quantitative magnetic resonance spectroscopy (qMRS) of the human brain, intended for clinical use. The implemented method was based on standard spatially selective MRS sequences. LÄS MER

  5. 14. Modern multimodal methods in brain MRI

    Författare :David Abramian; Anders Eklund; Evren Özarslan; Ida Blystad; Hamid Behjat; Jesper Andersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Functional MRI; Diffusion MRI; Graph signal processing; Deep learning;

    Sammanfattning : Magnetic resonance imaging (MRI) is one of the pillars of modern medical imaging, providing a non-invasive means to generate 3D images of the body with high soft-tissue contrast. Furthermore, the possibilities afforded by the design of MRI sequences enable the signal to be sensitized to a multitude of physiological tissue properties, resulting in a wide variety of distinct MRI modalities for clinical and research use.
