Opis:: Nowadays magnetic resonance imaging is used for anatomical assessment of human brain structures in neurodegenerative disorders causing brain atrophy for instance in multiple sclerosis (MS) or in Alzheimer Disease. Pathological brain tissue loss can be described in terms of change in the brain parenchymal fraction (BPF). This work shows the impact of segmentation method in SPM12 and additional segmentation in Computational Anatomy Toolbox (CAT12) on calculated BPF value for patients suffer from with MS no treated and treated with disease-modifying drug (DMD) interferon-beta (INFb) for one year and two years. Both methods confirm that brain parenchymal fraction decreases with age, nevertheless for patients not treated INFb decreases faster than for treated. An usability of Lesion Segmentation Tool toolbox in process of automatic detection and segmentation T₂ hyperintense lesions in FLAIR images is discussed.

Opis:: Functional magnetic resonance imaging (fMRI) was used to characterize relevant functional areas adjacent to the tumor what has important implications for surgical intervention. The aim of our study was to evaluate the functional areas of Broca and Wernicke responsible for production and understanding the speech which are very important from the point of view patients quality life using different variants of analysis available in the SPM package. Brain activity imaging with FWE controlling seems to be more appropriate than this with un uncorrected thresholds in clinical diagnostic. However analysis in the SPM should be carried out with great care taking into consideration that results can be influenced by parameters used in statistical approaches.
