  1. 21. MRI in multiple sclerosis : early detection, cortical lesions and gadolinium retention

    Författare :Yngve Forslin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Multiple sclerosis (MS) is a common neuroinflammatory and -degenerative disease. Magnetic Resonance Imaging (MRI) facilitates the diagnosis of MS, providing means to initiate early treatment and improving the long-term outcome. LÄS MER

  3. 22. A Rapid Differential Diagnostic Method for Detection of Post-Neurosurgical Infections

    Författare :Amir Ramezani; Annette Theodorsson; Aki Laakso; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This work pertains to the application of a biochemical assay with the purpose of monitoring for and early discovery of an active bacterial infection through direct sampling and rapid testing of the Cerebrospinal Fluid (CSF). A diagnostic device is described and evaluated, which aids in quickly discerning, verifying, or ruling out active infection at the injury site. LÄS MER

  4. 23. Detection and Quantification of Variable Viral RNA by Real-Time PCR Assays

    Författare :Shaman Muradrasoli; Jonas Blomberg; Göran Friman; Maria Brytting; Uppsala universitet; []
    Nyckelord :Virology; Diagnosis of Viral RNA; QPCR; RNA virus; broadly targeted PCR; probe design strategy; Infectious diseases; Medicin; Medicine;

    Sammanfattning : As the area of nucleic acid based technologies develops, so will our understanding of how structural variations in DNA and RNA pathogens are associated with disease. The overall goal of this thesis is the development of broadly targeted measurement techniques for variable viral RNA by Real-Time PCR (here referred to as quantitative reverse transcriptase PCR, QRT-PCR).

  5. 24. Timed Up-and-Go Dual-Task Tests for Early Detection of Dementia Disorder

    Författare :Hanna Bozkurt Åhman; Anna Cristina Åberg; Martin Ingelsson; Erik Rosendahl; Jorunn Helbostad; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dual-task; dementia; mild cognitive impairment; subjective cognitive impairment; Geriatrics; Geriatrik;

    Sammanfattning : Dementia constitutes an important and growing public health concern. There is a need for new, simple, and inexpensive methods to detect dementia disorders early in the disease progression. For this purpose, dual-tasking, i.e. LÄS MER

  7. 25. Improvements of SPECT by a new collimator design and simultaneous transmission-emission tomography

    Författare :Shahrokh Kimiaei; Marija Ivanovic; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gamma camera; SPECT; Emission tomography; Transmission tomography; Planar-concave collimators; Spatial resolution; Other physics; Övrig fysik; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : SPECT (Single Photon Emission Computed Tomography) and planar scintigraphy are the most established and world wide-spread nuclear medicine imaging techniques for clinical use today. SPECT is a tomographic technique that allows 3-D visualization of biochemical processes or physiological flow in the human body by external detection of photons from an administered radiopharmaceutical.
