The aim of the study is to present the possibilities and advantages of the synthetic magnetic resonance as the additional tool for the reconstruction of MRI image. In the end of a 6-minutes long scanning, which is the duration of the sequence, two parametric maps are made based on the tissue characteristics: R1 and R2 relaxation maps. SyMRI uses quantitative examination of multiple physical characteristics in order to reconstruct different contrast of the tissues from single scanning. Synthetic MRI is currently available for the clinical use and it represents the promising imaging technique, especially in child population.</p> Merim Jusufbegović, Esad Voloder, Fuad Julardžija, Adnan Šehić, Samija Pandžić, Tahira Maksumić Copyright (c) 2019 Radiološke tehnologije https://creativecommons.org/licenses/by/4.0/ https://www.uimr.ba/journal/index.php/rt/article/view/2 Mon, 28 Sep 2020 00:00:00 +0000 Inovativne tehnike kraniospinalne iradijacije - kontrola doze na spojevima zračnih snopova https://www.uimr.ba/journal/index.php/rt/article/view/3 <p>A particularly important issue in delivery of craniospinal irradiation (CSI) is reduction of geometric inaccuracy at the beam junctions. Overlapping at the beam junctions can result in overdosage (Hot Spot) and serious normal tissue complication (NTCP - Normal Tissue Complication Probability). Gaping at the beam junction can result in underdosage (Cold Spot) significantly increase the possibility of tumor recurrence (TCP - Tumor Control Probability). A modification of the craniospinal irradiation technique was proposed with the aim to improve dose control at the beam junctions and reduce appearance of cold and hot spots.<br>Based on results obtained by the portal imaging study carried out in the actual treatment situation, a simulation of the geometric inaccuracy and its effect to dose distribution was made. Results are compared with the results obtained by simulation of hot and cold spots in the treatment plan.<br>Results do not show significant deviation in the distribution of radiation dose, nor the deviation of the local dosage maximum at the beam junction. There is noticeable deviation of the dose distribution within few individual fractions as a result of geometric inaccuracy during treatment delivery reduced according to local protocol. The proposed modification, combined with a strict portal verification protocol, improves the irradiation technique regarding to dose control at the beam junctions.</p> Muhamed Topčagić, Hasan Osmić, Edis Đedović Copyright (c) 2019 Radiološke tehnologije https://creativecommons.org/licenses/by/4.0/ https://www.uimr.ba/journal/index.php/rt/article/view/3 Mon, 28 Sep 2020 00:00:00 +0000 Savremene dijagnostičke metode u nuklearnoj medicini - detekcija CNS oboljenja PET metodom https://www.uimr.ba/journal/index.php/rt/article/view/4 <p>Nowadays PET is intensively used in the research of different disorders of central nervous system (CNS). A whole series of the positron radiopharmaceuticals has been developed for the noninvasive examination of the brain metabolism of glucose, cerebral blood flow, neurotransmitter systems, usually labeled as 11C, 13N, 18F. The positron emission tomography (PET) is an important method in the functional imaging of the brain that enables in vivo researches of brain functions, and it is possible to research almost every aspect of brain functions due to present-day development. In clinical practice, but in researches, as well, the most used is 18F-fluoro-deoxyglucose (FDG). Physical characteristics<br>enable easier production and usage, and it is used for studying and estimation of disorders of glucose metabolism in many pathological conditions of the brain.<br>In the past PET was mostly used in the researches because of relatively high cost and complexity of accompanying infrastructure, such as cyclotrons, PET camera and radiochemical laboratory. In the last few years due to the development in the technology and prevalence of PET cameras, PET is more and more used in clinical neurology enabling the better comprehension of the disease and pathogenesis, it facilitates establishing a diagnosis, it enables prognostics following the development of the disease, as well as the response to the applied therapy. Special advantages of the molecular imaging lie in the fact that sophisticated biological processes and specific ways in certain disease can be explained on cellular and molecular level in human and other living systems. Besides, molecular imaging can provide the information on clinical changes before the pathological factors appear, thus enabling the diagnosis of the disease in the early stages and the help in the therapeutic examinations of many CNS disorders.</p> Halil Ćorović, Nusret Salkica, Belma Tukić, Elvira Đozo Copyright (c) 2019 Radiološke tehnologije https://creativecommons.org/licenses/by/4.0/ https://www.uimr.ba/journal/index.php/rt/article/view/4 Fri, 08 Nov 2019 00:00:00 +0000 Neuronavigacija kod operativnih zahvata na mozgu https://www.uimr.ba/journal/index.php/rt/article/view/5 <p>Medical imaging has been used primarily for diagnosis.<br>This process requires three-dimensional localization devices, the ability to register medical images to physical space, and the ability to display position and trajectory on those images Neuronavigation provides intraoperative orientation to the surgeon and helps in planning a precise surgical approach to the targetted lesion and defines the surrounding neurovascular structures. Incorporation of the functional data provided by computed tomography and magnetic resonance imaging or ultrasound with neuronavigation renders neurosergeons to avoid the vital areas of the brain during surgery.</p> Adila Delić, Mirza Morankić Copyright (c) 2019 Radiološke tehnologije https://creativecommons.org/licenses/by/4.0/ https://www.uimr.ba/journal/index.php/rt/article/view/5 Mon, 28 Sep 2020 00:00:00 +0000 Radioterapija postoperativnih glioblastoma i verifikacija tretmana savremenim radioterapijskim tehnikama https://www.uimr.ba/journal/index.php/rt/article/view/6 <p>Purpose: To present the importance and severity of the issue in patients with glioblastoma through median and over all survival. To highlight new achievements in modern radiotherapy as one of the modes of treatment for glioblastoma, and advanced techniques of delivery and treatment verification.<br>Methods: As a material and methods for the preparation of this review article, articles were used choosing systematically on internet science databases.<br>Results: Glioblastoma multiforme (GBM) is the most common malignant tumor of the brain, which is ultimately a fatal disease, with median survival of 16.6 months and 2 years of survival of 26,5%, and total five-year survival is about 4%. The clear benefits of survival have been demonstrated by the use of postoperative radiotherapy (RT) prescribed at dose of 50 to 60 Gy. Attempts to escalate doses over 60 Gy lead to increased toxicity, without additional survival benefits.<br>The current standard treatment involves the simultaneous application of chemotherapy and radiotherapy to 60Gy / 2Gy daily for 30 days, IMRT or VMAT techniques, followed by adjuvant treatment of temozolomide for 6 months.<br>Hypofractioned RT is associated with a small effect on total survival, it can be applied to recurrent glioblastoma. Stereotactic radiosurgery is an effective therapy for relapsed GBM, but is usually associated with a significant toxicity, and is applied after assessment of the patient's general condition and performances.<br>Conclusion: Although glioblastoma is ultimately a fatal disease, the studies have shown respectable results in postoperative treatment with a combination of chemotherapy and radiotherapy, using modern techniques to deliver and treatment verification.</p> Enis Tinjak, Velda Smajlbegović, Mirjana Ristanić, Mirza Jačević Copyright (c) 2019 Radiološke tehnologije https://www.uimr.ba/journal/index.php/rt/article/view/6 Mon, 28 Sep 2020 00:00:00 +0000 Magnetno-rezonantna perfuzija (MRPWI) mozga https://www.uimr.ba/journal/index.php/rt/article/view/7 <p>MR brain perfusion represents the diagnostic method by which brain perfusion is being followed, that is brain blood supply.
