  1. 16. Anterior Cruciate Ligament injury, Patient Variables, Outcomes and Knee Osteoarthritis

    Författare :Paul Neuman; Enheten för led- och mjukvävnadsforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; meniscal injury; knee osteoarthritis; knee radiography; Anterior cruciate ligament injury ACL ; delayed gadolinium-enhanced MRI of cartilage dGEMRIC ;

    Sammanfattning : The ruptured anterior cruciate ligament (ACL) leads to immediate symptoms that severely affect the individual and receives great attention among the scientific community, yet there is still no consensus on the optional form of treatment. An ACL injury is also a well known high risk factor for the development of knee osteoarthritis (OA) some decades later. LÄS MER

  3. 17. Human studies evaluating dGEMRIC as a prognostic tool for knee osteoarthritis

    Författare :Henrik Owman; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Delayed gadolinium-enhanced MRI of cartilage dGEMRIC ; knee; cartilage; glycosaminoglycan; anterior cruciate ligament injury; meniscal injury; osteoarthritis; joint space narrowing; osteophyte;

    Sammanfattning : Osteoarthritis (OA) is the most common joint disorder worldwide, causing joint pain and stiffness. The current gold standard for diagnosing knee OA is radiography. However, the disease has often progressed well beyond the point of no return once radiographic cartilage changes become visible. LÄS MER

  4. 18. Evaluation of the Dual-Modal usage of contrast agents by means of Synchrotron X-ray Computed Microtomography and Magnetic Resonance Imaging using Macrophages loaded with Barium Sulfate and Gadolinium Nanoparticles for Detection and Monitoring in Animal Disease Models

    Författare :Emanuel Larsson; Kajsa Uvdal; Agostino Accardo; Giuliana Tromba; Albert E. Siegbahn; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : ¨This thesis focuses on evaluating the dual-modal Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) capabilities of contrast agents. For such purposes a gadolinium based contrast agent is of high interest, due to its paramagnetic properties, which while present inside a magnetic field will hence interact with the protons spins of water (in tissue and fat) and shorten their the T1 relaxation time, thereby creating a positive image contrast in MRI.

  5. 19. Suspension plasma sprayed thermal barrier coatings for internal combustion engines

    Författare :Wellington Uczak de Goes; Nicolaie Markocsan; Mohit Kumar Gupta; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coatings; Suspension Plasma Spraying; Gadolinium Zirconate; Internal Combustion Engines; Engine Efficiency; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : The upward trend in internal combustion engine efficiency is likely driven by the depletion of fossil fuels. Since no replacement in sight can deliver energy comparable to the conventional oil, there is a need to use it more rationally and effectively. LÄS MER

  7. 20. Magnetic resonance imaging in chronic Achilles tendinopathy

    Författare :Adel Shalabi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Achilles tendon; tendinopathy; MRI; gadolinium contrast; 3-D seed growing; surgery; eccentric training.;

    Sammanfattning : The main objective of this thesis was to evaluate and monitor the morphological response following treatment interventions in patients with chronic Achilles tendinopathy by using different MRI-techniques. For this purpose. LÄS MER
