Analysis of pathological brain tissue from MRI data

Due to the high resolution of soft tissue, magnetic resonance imaging plays a crucial role in the diagnosis and therapy planning in the neurosurgery field whereas it is necessary to determine which pathology in the brain tissue is involved. Glioblastoma multiforme, metastatic tumours, lymphomas, and abscesses are examined in detail from magnetic resonance images. In clinical practice, all mentioned pathologies are diagnosed through invasive methods in the form of biopsy followed by histology of the affected tissue. This work is focused on an alternative non-invasive method of tumour diagnosis. The method is based on the data analysis from defined curves (drawn into the apparent diffusion images) that lead from the tumour area through peritumoral edema, up to healthy tissue. The analysis of descending and ascending parts of the curve could lead to non-invasive diagnostics of the pathological tissue
