Multiple sclerosis is a chronic demyelinating disease of the central nervous system, that causes permanent disabilities. Diagnostics of this disease by magnetic resonance requires the appliance of corresponding protocols with the sequences that emphasize demyelinating plaques. Standard sequences T1 and T2 sometimes cannot clearly show demyelinating plaques, and it is necessary to work on perfecting the sequences that emphasize the changes in the brain formed as demyelinating plaques. The aim of the survey: The aim of the survey was to estimate the value of MR sequence with double inversion recovery (DIR) in discovering demyelinating lesions of the brain in multiple sclerosis (MS). Patients and methods of the survey: 22 patients were included in the survey, they were of both genders and different age. The patients were with diagnosed with multiple sclerosis. The patients underwent the scanning on MR apparatus 1.5 T. Comparison of DIR sequence to FLAIR and T2 W sequences were done. Result: DIR sequence proved significantly more MS lesions compared to T2W or FLAIR sequence, including intracortical, juxtacortical and paraventricular zone of the brain. In the infratentorial zone of brain, T2W sequence proved significantly more plaques compared to DIR and FLAIR. Conclusion: DIR sequence compared to T2W and FLAIR sequences discovered more demyelinating lesions in targeted regions that were examined. DIR sequence is a tool that contributes to easier and faster diagnostics of multiple sclerosis, needs to be included into the routine MR protocol of patients with MS, in order to discover more easily intracortical and juxtacortical MS lesions of the brain.

Introduction: This study aims to explore clinical values and possibilities of heart artifact elimination for patients who underwent SPECT myocardial perfusion scintigraphy. The main focus is on nuclear medicine technologists and their knowlodge of the new technologies developed in nuclear cardiology. Methods: A qualitative descriptive study, review article has been performed for this research. Pubmed, Web of Science, and Embase were searched using a predefined electronic search strategy. Eighteen studies were deemed eligible for this systematic review. Results: Based on the literature we found average age for the patients with coronary artery disease is 59.69 years for women and 57.39 yeras for men. False positive findings, blurred images, respiratory artifacts and sinogram and linogram interruption is very often, especially with patients with irregular breathing cycles, fear of the reasults, anxiety and patients with high BMI. Many studies performed on phantoms or on patients suggest image artifacts can be reduced or even eliminated with the new scanning methodology, software application upgrade, and with right nuclear medicine technologist education. Conclusion: Coronary artery disease can affect men and women equally so the best diagnostic modality is essential for adequate treatment. Interruption of sinogram or linogram, truncation of the heart and blurred image is the first sign artifact of the image. Essential and the first step of every cardiac proccesing software is sinogram and linogram inspection combined with motion correction evaluation of the raw images. New technologies can improve image quality which can increase sensitivity and specificy of myocardial perfusion scintigraphy in all patients.

In this way, a series of average daily values of inflow into accumulation was obtained for the period from 1980 to 2012. year. Interpretation of these data was done in the form of variation of annual inflows in the observed period, as well as average flow curve curves. By reviewing the previous measurements and surveys, it can be concluded that there is a more pronounced cyclicality of inflows over a longer period of time, with driers of dry and rainy periods. On the other hand, having in mind the natural correlation between the inflow of water and the spread of the deposit, it is logical to hypothesize that at the time of the hydrological maximum, the input is higher in the accumulation. Another important indicator of the hydrological regime of the lake is the duration of the inflow into the accumulation "Modrac". This curve points to the vast hydrological regime of the watercourse in the basin of the reservoir. In this regard, it should be noted that all watercourses in Bosnia and Herzegovina and the region, with a basin area of up to 1000 km2, have such a regime. Bearing in mind the similarity of physical and geographical conditions in the region, this analogy is quite logical. The hectic hydrological regime is characterized by a short duration of large waters and a very long duration of small water, as well as a large flow range (Qmax / Qmin).

The Editors' Network of the European Society of Cardiology (ESC) provides a dynamic forum for editorial discussions and endorses the recommendations of the International Committee of Medical Journal Editors (ICMJE) to improve the scientific quality of biomedical journals. Authorship confers credit and important academic rewards. Recently, however, the ICMJE emphasized that authorship also requires responsibility and accountability. These issues are now covered by the new -(fourth) criterion for authorship. Authors should agree to be accountable and ensure that questions regarding the accuracy and integrity of the entire work will be appropriately addressed. This review discusses the implications of this paradigm shift on authorship requirements with the aim of increasing awareness on good scientific and editorial practices.
