  1. 1. Adaptive analysis of functional MRI data

    Författare :Ola Friman; William M. Wells III; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Functional Magnetic Resonance Imaging (fMRI) is a recently developed neuroimaging technique with capacity to map neural activity with high spatial precision. To locate active brain areas, the method utilizes local blood oxygenation changes which are reflected as small intensity changes in a special type of MR images. LÄS MER

  3. 2. Multidimensional MRI  of Myocardial Dynamics : Acquisition, Reconstruction and Visualization

    Författare :Andreas Sigfridsson; Hans Knutsson; Sebastian Kozerke; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Cardiac motion; myocardial dynamics; strain; tensor; deformation; DENSE; k-t BLAST; Medical engineering; Medicinsk teknik;

    Sammanfattning : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all rely on the quality of the measurements of heart dynamics. LÄS MER

    Sammanfattning : Magnetic resonance imaging (MRI) is a very versatile imaging modality which can be used to acquire several different types of images. Some examples include anatomical images, images showing local brain activation and images depicting different types of pathologies. LÄS MER

  5. 4. 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
