  1. 1. Clinical Applications of Synthetic MRI of the Brain

    Author : Ida Blystad; Elna-Marie Larsson; Peter Lundberg; Marcel Warntjes; Örjan Smedby; Anne-Marie Landtblom; John Hald; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Magnetic Resonance Imaging (MRI) has a high soft-tissue contrast with a high sensitivity for detecting pathological changes in the brain. Conventional MRI is a time-consuming method with multiple scans that relies on the visual assessment of the neuroradiologist. READ MORE

  2. 2. Preoperative MRI and PET in suspected low-grade gliomas : Radiological, neuropathological and clinical intersections

    Abstract : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. READ MORE

  3. 3. Creep Behavior of High Temperature Cast Materials for Exhaust Applications

    Author : Christian Öberg; Stefan Jonsson; Baohua Zhu; John Hald; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Creep; creep behaviour; creep damage; ductile cast iron; high-alloyed austenitic cast steel; thermal cycling; tensile testing; stress relaxation; oxidation; precipitation.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : This thesis focuses on creep of four cast materials intended for exhaust manifolds in heavy-duty truck engines. Two of the materials are ferritic ductile cast irons, SiMo51 and SiMo1000, one is an austenitic ductile cast iron, D5S, and another one is an austenitic cast steel, HK30. READ MORE
