  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 : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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. Perfusion MRI of the brain after radiotherapy in patients with glioblastoma – potential and problems

    Author : Markus Fahlström; Elna-Marie Larsson; Tufve Nyholm; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Perfusion Magnetic Resonance Imaging (MRI) is a useful tool in diagnostic evaluation and treatment response assessment in patients with glioblastoma. The standard treatment regimen includes surgical resection, radiotherapy and adjuvant chemotherapy. However, prognosis is poor; relative 5-year survival is 3–5%. READ MORE

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

    Author : Anna Falk Delgado; Elna-Marie Larsson; Anja Smits; Jens Sörensen; John Hald; Uppsala universitet; []

    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

  4. 4. ­­­Visual assessment of perfusion and metabolism in neurodegenerative dementia

    Author : David Fällmar; Elna-Marie Larsson; Lena Kilander; Mark Lubberink; Ian Law; Uppsala universitet; []

    Abstract : Olfactory loss is a common non-motor symptom of Parkinson’s disease (PD), often preceding the cardinal motor symptoms of the disease. The aim of this thesis was to: (a) evaluate whether olfactory examination can increase diagnostic accuracy, and (b) study the structural and functional neural basis of olfactory dysfunction in PD with different applications of Magnetic Resonance Imaging (MRI).
