[MR imaging of acute disseminated encephalomyelitis and multiple sclerosis in children. A review (in English language)]

PATAY Zoltán

[Inflammatory diseases of the central nervous system (CNS) are relatively rare in children, but their relevance to public health is considerable due to frequent and significant long term morbidity and even mortality. As in adults, acute disseminated encephalomyelitis (ADEM) and multiple sclerosis (MS) and their variants are the most common entities in this group of pathologies in the pediatric patient population. Recent efforts have focused on establishing standardized diagnostic criteria... tovább »

[Current issues of neuroimaging diagnostics of multiple sclerosis]

BAJZIK Gábor

[Magnetic resonance imaging techniques have been routinely used in diagnostics and follow-up of multiple sclerosis and magnetic resonance imaging findings are incorporated into the current diagnostic criteria of the disease. International guidelines were created aiming to define the indication, timing, minimum requirements and interpretation of magnetic resonance examination in multiple sclerosis. In Hungary, there is a lack of widely-accepted standardized protocol, therefore presenting the... tovább »

[Application of diffusion weighted imaging in neuroradiology]

BARSI Péter

[Diffusion weighted magnetic resonance (MR) imaging is available on all modern MR scanners. It depicts the motion of water molecules in the brain tissue and intracranial foreign tissues and provides information on changes in the proportion of intra- and extracellular space and the characteristics of foreign intracranial tissues and fluids. It is of utmost importance eg. in the diagnostics and differential diagnostics of acute ischaemic brain lesions, the diagnostics of inflammatory brain... tovább »

[State of the art neurointerventional treatment of intracranial vascular anomalies]

SZIKORA István, BERENTEI Zsolt, MAROSFŐI Miklós, KULCSÁR Zsolt, GUBUCZ István

[Haemorrhagic stroke is frequently caused by rupture of intracranial vascular anomalies. The role of minimally invasive therapy in the treatment of such lesions has increased dramatically within the past two decades. The purpose of this study is to summarize the pathology and clinical features of these anomalies and to overview the potential applications of neurointerventional techniques in their treatment. Endovascular therapy is the first choice of treatment for most intracranial aneurysms.... tovább »

[Noninvasive imaging in the diagnosis of cerebral sinus thrombosis]

[Cerebral venous thrombosis is a severe, but potentially reversible disease, when it is promptly recognised and treated. Due to its varied and many aetiological factors and clinical manifestations, non-invasive radiological imaging plays a key role in the diagnostic procedure. Unenhanced and contrast-enhanced computer tomography (CT) and magnetic resonance (MR) imaging, CT angiography (CTA), MR angiography - such as time-of-flight (TOF) and phase-contrast (PC) angiography - are appropriate... tovább »

[Plasticity of brain lateralization in epilepsy: fMRI studies]

KALMÁR Zsuzsanna, WOERMANN Friedrich, SCHWARCZ Attila, JANSZKY József

[Aims - This review is a summary of four studies investigating the effect of epileptic disturbance and other functional factors on the brain lateralization. Methods - Patients were investigated by functional MRI by using visual, sensorimotor, memory, and speech paradigms. Results - 1. Malformations of cortical development localized within speech centers induce contralateral speech reorganization in only 50% of cases. 2. Epileptic disturbance can induce a reorganization in language... tovább »

[Clonazepam can facilitate sensorimotor functional MRI examinations in status epilepticus during sleep]

[Functional magnetic resonance imaging examinations became an integral part of epilepsy surgery workup. In the pediatric population these examinations are usually carried out in full anesthesia, however in some forms of epilepsy, e.g. electrical status epilepticus in sleep, anesthesia could jeopardize the success of the examination. Here, we show on the example of an eight-year-old polymicrogyric epileptic child, that clonazepam can help suppressing the epileptic activity during propofol... tovább »

[Interhemispheric asymmetry of diffusion parameters in the human brain]

WALTER Norbert, HORVÁTH Ildikó, VANDULEK Csaba, BERÉNYI Ervin, BOGNER Péter, TÓTH Lilla

[Our aim was to study the hemispheric asymmetry of the human brain through the simultaneous measurements of the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values within a homogeneous sample in regards to the gender, age and handedness. Method - Eleven young women were included in our diffusion study performed on a 1.5 T MR scanner. We calculated the ADC and FA values in nine-nine region of interest points of the brain. The diffusion values were measured symmetrically in... tovább »

[Diffusion weighted magnetic resonance imaging of metachromatic leukodystrophy - a case report]

PINTÉR Nándor, KOLLÁR Katalin, RUDAS Gábor, BARSI Péter

[We present the case of a 7 years old boy with the juvenile form of metachromatic leukodystrophy. Beside conventional sequences, a diffusion-weighted magnetic resonance study was performed. On T2-weighted images a diffuse hyperintensity of the cerebral white matter with a typical tigroid pattern was seen as a well-known characteristics of the disease. No difference was detectable on T2-weighted images between the different cerebral white matter regions. Diffusion study showed low apparent... tovább »
