[AIM OF THE STUDY - To perform functional MRI experiments at low magnetic field, and to set up routine protocol to help the planning of neurosurgical operations and the examination of epilepsy patients. METHODS - An optimized 2D EPI sequence was applied to yield functional MR images in basic paradigms such as finger tapping and internal word generation. Further, activation was induced also by a task involving mental navigation based on the retrieval of individually familiar visuo-spatial knowledge. RESULTS - Low resolution (matrix of 64×64) functional MR images satisfactorily visualized moto-sensor strip and speech centers. In the mental navigation task bilateral activation of formatio hippocampalis was observed. Determination of motor area was also performed in an epilepsy patient whose seizure focus had been found in the area of pre- and postcentral gyrus. The dislocation of the motor cortex was demonstrated. CONCLUSION - Functional MR images with fine quality can be obtained in basic paradigms even at low magnetic field if MR imaging parameters and paradigms are optimized.]

[The early-onset generalised dystonia is a dyskinetic movement disorder with a wide variety in phenotype and poor response to pharmacological treatment. A mutation on the DYT1 gene is responsible for the disease in more than 50% of cases with typical early-onset dystonia beginning in a limb. We describe the medical history of two brothers with first signs of focal dystonia at age 12 starting with right side lower limb dystonia of the older brother and writers cramp of the younger one. In both over a period of 6 and 10 years dystonia generalised. The negativ results of MRI, electrophisiological testing and muscle biopsy corroborate the diagnosis of primary dystonia. The DNA from the older patient was tested for the 3 bp deletion in exon 5 of the DYT1 gene by restriction enzyme. The positive result confirmed the diagnosis of early-onset primary dystonia. A short synopsis of routine molecular genetic tests indications and treatment options is outlined.]

[The aim of our research was to assess the incidence and the 12- and 24-month mortality of hospitalized stroke in Hungary. We analyzed the rate of mortality after stroke and compared it to the standard mortality rate of the population. To assess the incidence we extracted the data of “new” stroke patients (ICD- 10 diagnoses: I60-64) hospitalized in May 2003 from the database of the National Health Insurance Fund Administration. We regarded those as “new” patients who had not been treated with these primary or secondary diagnoses in the previous 24 months. Data were collected by sex and age (age groups: 25-44, 45-64, 65 and over). We analyzed the patients' survival on the basis of their April 2004 and April 2005 data. The incidence of the “new” hospitalized stroke patients was higher in men than in women; the incidence in the age group of 65 and over was 2112/100.000 in males and 1582/100.000 in females, the corresponding values in the 45-64 age group were 623 vs. 366 per 100.000, respectively. In 2003 more than 42 thousand “new” stroke patients were hospitalized in Hungary of whom over 10 thousand died in the first year, followed by a further 2 thousand in the second year. Women’s survival is more favourable than men's: in the first year it is 71.47% vs. 69.24% (65+ group), and 88.18% vs. 83.16% (45-64 group); in the second year the corresponding values are 66.95% vs. 61.62% (65+), and 85.45% vs. 80.90% (45-64), respectively. The risk of death in the first year after stroke, compared to the standard population, is 5.17- fold in women and 4.70-fold in men in the total sample, and 10-15-fold in the 45-64 group. There are large differences by gender, particularly in men of the working age groups (25-44, 45-64), whose mortality is twice as high as that of women of the same age.]

[Our aim was to assess the social insurance costs of hospital treatments for acute stroke in Hungary between 2003 and 2005. We studied how much burden stroke patients impose on the financer (National Health Insurance Fund Administration) in acute and chronic hospital admissions. We extracted the data of “new” stroke patients (ICD-10: I60-64 diagnosis) hospitalized in May 2003 from the database of the financer. We analyzed active and chronic hospital treatment costs of these patients in the period of 12 months before the stroke and in the following first and second 12 months. Data were collected by sex and age (age groups: 25-44, 45-64, over 65). We studied patients hospitalized in May 2003 with the ICD-10: I60-64 main diagnosis but not being treated with the same diagnosis in the previous 24 months. In the first 12 months of the active care the burden of the disease was (male vs. female) 65+: 254.6 vs. 205.8; 45-64: 341.4 vs. 280.5; 25-44: 370.1 vs. 306.1 thousand HUF per patient. In the second 12 months the costs were 50.6 vs. 36.2; 24.2 vs. 32.6; 27.6 vs. 24.8 thousand HUF respectively. In the first year following the episode the costs of the chronic hospital treatment were (age groups as above) 23.3 vs. 31.3; 28.9 vs. 22.2; 22.8 vs. 22.5 thousand HUF. A year later the chronic hospital costs were 9.0 vs. 10.9; 6.7 vs. 12.2; 1.4 vs. 38.1 thousand HUF respectively. Average costs of stroke are higher in the case of males as are in the case of females, 364.8 vs. 303.0 thousand HUF in the first 24 months. The remarkable difference results from active hospital treatment costs (331.5 vs. 262.1 thousand HUF), while the discrepancy is smaller in the chronic hospital care (33.3 vs. 40.9 thousand HUF).]

[Comparison of subthalamic nucleus planning coordinates in 1Tesla and 3Tesla MRI for deep brain stimulation targeting ]

[Backgroud - Deep brain stimulation (DBS) involves placing electrodes within specific deep brain nuclei. For movement disorders the most common indications are tremors, Parkinsons disease and dystonias. Surgeons mostly employ MR imaging for preoperative target selection. MR field geometrical distortion may contribute to target-selection error in the MR scan which can contribute to error in electrode placement. Methods - In this paper we compared the STN target planning coordinates in six parkinsonian DBS patients. Each patient underwent target planning in 1T and 3T MRI. We statistically compared and analysed the target-, and the fiducial coordinates in two different magnetic fileds. Results - The target coordinates showed no significant differences (Mann-Whitney test, p > 0.05), however we found significant difference in fiducial coordinates (p < 0.01), in 3T MRI it was more pronounced (mean ± SD: 0.8 ± 0.3 mm) comparing to 1T (mean ± SD: 0.4 ± 0.2 mm). Conclusion - Preliminary results showed no significant differences in planning of target coordinates comparing 1T to 3T magnetic fields.]

[Aim of the study - Presentation of functional MRI performed at low magnetic field (1 Tesla) for planning microsurgical operation in a patient suffering from tumor close to an eloquent brain area. Methods - Microsurgical removal navigated by frameless stereotaxy of an intrinsic tumor located in eloquent area is indicated if speech function is not damaged, i.e. exact localisation and relationship of the tumor and speech area can be defined. Before operation an optimized EPI based 2D sequence was applied to yield functional MR images. At the planning of the operation the paradigm used for the localization of the sensory language cortex contained passive listening to a text. Control investigations were performed one month postoperatively. A specific psychological test, as an additional investigation to estimate the accurate level of the sensory language function, was also conducted. Results - Low resolution (matrix of 64×64) functional MR images visualized sensory speech center and auditory cortex satisfactorily. The scans showed clearly that the Wernicke's region was situated just above the tumor (WHO grade II glioma), and this finding increased the safety of intraoperative localization and reduced the risk of morbidity. Control examinations revealed minimal decrease in sensory language function, however, it was not noticeable for either the patient or her surroundings. Conclusion - Optimized functional MR imaging performed at low magnetic field can support planning of neurosurgical operations and reduce the morbidity of microsurgical interventions.]
