1. Clinical Applications of Synthetic MRI of the Brain
Sammanfattning : 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. LÄS MER
2. Perfusion MRI of the brain after radiotherapy in patients with glioblastoma – potential and problems
Sammanfattning : 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%. LÄS MER
3. Preoperative MRI and PET in suspected low-grade gliomas : Radiological, neuropathological and clinical intersections
Sammanfattning : 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. LÄS MER
4. Visual assessment of perfusion and metabolism in neurodegenerative dementia
Sammanfattning : A worldwide demographic shift is currently occurring, with rapidly increasing numbers of elderly individuals. Since the incidence of neurodegenerative disease generally increases with age, this entails an increase in dementia prevalence. LÄS MER
5. Imaging Studies of Olfaction in Health and Parkinsonism
Sammanfattning : 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).
