Recently, a novel leukoencephalopathy syndrome was described in eight patients with a distinct pattern of MRI abnormalities. Here we describe the clinical, laboratory, and MRI findings in five new, unrelated patients. The clinical picture was homogeneous with onset in childhood, a slowly progressive course, variable mental deficits, signs of pyramidal and(More)
THE AIM OF THE STUDY Paper describes a study of language lateralization of patients with brain tumors, measured by preoperative functional magnetic resonance imaging (fMRI) and comparison results with tumor histology and profile of functional asymmetry. METHODS During the study 21 patient underwent fMRI scan. 15 patients had a tumor in the left and 6 in(More)
The authors analyzed correlations of amplitude and latency levels of N100, N200 and P300 components of acoustic evoked potentials (AEP) registered during sonic stimulation and counting of target-oriented stimuli in 22 patients in vegetative state and mutism as an outcome of traumatic brain injury. Results were analyzed with association of(More)
BACKGROUND Diffuse axonal injury (DAI) causes neurodegenerative processes in brain which can last weeks and months after traumatic brain injury. Aim of this study was to assess structural changes of corpus callosum and corticospinal tracts in dynamics using diffusion-tensor magnetic resonance imaging (DT-MRI) in severe DAI. MATERIALS AND METHODS 14(More)
UNLABELLED The aim of the study was to assess the capabilities of diffusion kurtosis imaging (DKI) in diagnosis of the glioma proliferative activity and to evaluate a relationship between the glioma proliferative activity index and diffusion parameters of the contralateral normal appearing white matter (CNAWM). MATERIAL AND METHODS The study included 47(More)
MATERIAL AND METHODS A total of 50 patients were examined prior to surgical resection of intracranial tumors of the temporal and frontal lobes. Left-sided tumors were observed in 33 patients and right-sided tumors were observed in 17 patients. The functional asymmetry profile was determined using self-assessment, the Annet questionnaire, and the dichotic(More)
This paper analyzes the variation of the functional anatomy of the brain in healthy people performing identical activities on the basis of functional magneticresonance imaging (fMRI). According to the authors, this approach allows you to showcase a variety of individual strategies to achieve the same external (behavioral) result intracerebral different(More)
