Beside the visual insight of FDG pathways into the human body, PET/CT can give valuable information based on the SUV values. The SUV is a quantitative parameter of metabolic activity. FDG application has 2 major impacts on PET/CT: qualitative aspect (visual insight of FDG in the body) and quantitative aspect (degradation of the SUV values). Based on the literature, FDG extravasation incidence is 31% for all PET/CT studies and in 8% of all cases extravasation has been visually confirmed since the application place has been in the field of view. By constantly developing the technique, work methodology and increasing the quality control of the staff in the PET/CT department, the incidence of extravasation can be significantly reduced based on the results from the literature. In the case when paravenous injection is present on PET/CT images we can use certain software procedures to improve image quality and SUV quanitification.</p> Nusret Salkica Halil Ćorović Safet Hadžimusić Adel Brčaninović Copyright (c) 2020 Nusret Salkica, Halil Ćorović, Safet Hadžimusić, Adel Brčaninović 2020-11-07 2020-11-07 11 1 3 8 10.48026/isnn.26373297.2020.11.1.1 Adaptive radiotherapy for head and neck cancer <p><strong>Introduction:</strong> Radiation therapy has long played an integral role in the manage¬ment of locally advanced head and neck cancer (HNC), both for organ preservation and to improve tumor control in the postoperative setting. The aim of this research is to investigate the effects of adaptive radiotherapy on dosimetric, clinical, and toxicity outcomes for patients with head and neck cancer undergoing radiation therapy treatment. Many sources have reported volume reductions in the primary target, nodal volumes, and parotid glands over treatment, which may result in unintended dosimetric changes affecting the side effect profile and even efficacy of the treatment. Adaptive radiotherapy (ART) is an interesting treatment paradigm that has been developed to directly adjust to these changes.<br><strong>Material and methods:</strong> This research contains the results of 15 studies, including clinical trials, randomized prospective and retrospective studies. The researches analyze the impact of radiation therapy on changes in tumor volume and the relationship with planned radiation dose delivery, as well as the possibility of using adaptive radiotherapy in response to identified changes. Also, medical articles and abstracts that are closely related to the title of adaptive radiotherapy were researched.<br><strong>Results:</strong> The application of ART significantly improved the quality of life of patients with head and neck cancer, as well as two-year locoregional control of the disease. The average time to apply ART is the middle of the treatment course approximately 17 to 20 fractions of the treatment.<br><strong>Conclusion:</strong> Based on systematic review of the literature, evidence based changes in target volumes and dose reduction at OAR, adaptive radiotherapy is recommended treatment for most of the patients with head and neck cancer with the support of image-guided radiotherapy.</p> Enis Tinjak Velda Smajlbegović Adnan Beganović Mirjana Ristanić Halil Ćorović Adel Brčaninović Copyright (c) 2020 Enis Tinjak, Velda Smajlbegović, Adnan Beganović, Mirjana Ristanić, Halil Ćorović, Adel Brčaninović 2020-11-07 2020-11-07 11 1 9 16 10.48026/isnn.26373297.2020.11.1.2 The mechanical thrombectomy during coil embolisation of the ruptured intracranial aneurysm <p>Experience in managing thromboembolic complications of distal blood vessels during coil embolization in the case of subarachnoid hemorrhage (SAH) is still limited. This is the presentation of the case of a 23-year-old man with a ruptured small aneurysm who experienced thromboembolic occlusion during coil embolization. Mechanical thrombectomy resulted in complete recanalization of the occluded branches without ischemic complications. This case should be used for the use of mechanical thrombectomies as an effective rescue strategy and treatment of distal arteries occlusions of the brain.</p> Deniz Bulja Odej Ali Abud Merim Jusufbegović Sandra Vegar - Zubović Copyright (c) 2020 Deniz Bulja, Odej Ali Abud, Merim Jusufbegović, Sandra Vegar - Zubović 2020-11-07 2020-11-07 11 1 41 43 10.48026/isnn.26373297.2020.11.1.7 Knowledge, attitudes and practice in the field of the radiation protection of medical radiology engineers in radiotherapy <p><strong>Introduction:</strong> The engineers of the medical radiology in radiotherapy are key professional group directly responsible for reliable delivery of radiation therapy treatment and the implementation of radiation protection measures in practice. Therefore, their knowledge and skills in this area need to be adequate and up to date. The aim of this research is the assessment of knowledge, attitudes and practice in the field of radiation protection among the engineers of medical radiology employed in radiotherapy centers within the public healthcare system in Bosnia and Herzegovina.<br /><strong>Material and methods:</strong> The research was conducted on a sample of 30 engineers of medical radiology using a structured questionnaire which contains demographic data and sets of 10 questions related to radiotherapy devices, radiation protection in radiotherapy, risks and incidents related to use of ionizing radiation and the role of medical radiology engineers in radiation protection system.<br /><strong>Results:</strong> The results of the research show optimal level of knowledge in the field of radiation protection (74.66%) and optimal level of awareness of the risks associated with the use of ionizing radiation (72%). The level of knowledge and awareness is significantly higher among respondents with longer working experience and those who have completed master’s degree and postgraduate education in the field of radiation protection. The application of ionizing radiation protection measures in practice has been assessed as satisfactory (2,3). Respondents are not sufficiently involved in the work of regulatory bodies (26.7%), decisionmaking (23.3%), development of procedures (23.3%) and education of other employees in the field of radiation protection (2.7%).<br /><strong>Conclusion:</strong> Engineers of medical radiology are not fully involved in the radiation protection system as educated and trained professionals. One of the most important professional interests of engineers of medical radiology is adequate influence on the processes in the field of radiation protection.</p> Muhamed Topčagić Amer Šoše Enis Tinjak Marin Zovko Haris Čizmić Copyright (c) 2020 Muhamed Topčagić, Amer Šoše, Enis Tinjak, Marin Zovko, Haris Čizmić 2020-11-07 2020-11-07 11 1 17 22 10.48026/isnn.26373297.2020.11.1.3 The significance of mammography and ultrasound examination in the diagnosis of breast cancer <p><strong>Introduction:</strong> Mammography represents a very accessible diagnostic method that has been accepted as the initial method of examining women over the age of 40 worldwide. It is a method with a high percentage of accuracy (80-90%) in the detection of breast cancer in patients without symptoms. However, there may be a significant overlap of mammographic presentation of benign and malignant changes in the structural tissue of the breast. The ultrasound method of breast examination is invaluable in breaking down between solid and cystic changes, as well as for clarifying palpable lumps in the breast. In almost 98% of cases, ultrasound examination can distinguish whether it is a benign or malignant change. The aim of this study is to prove the correlation between mammography and ultrasound methods of breast examination.<br><strong>Material and methods:</strong> The examination was performed as a retrospective - prospective descriptive study in the Department for radiological and ultrasound diagnostics of the Derventa Health Center. The study included 80 female respondents who consented to the recording. Based on the performed ultrasound and mammography images, a qualitative analysis was made. A comparison of the sensitivity of the breast imaging between mammography and ultrasound imaging was performed.<br><strong>Results:</strong> Comparing mammography and ultrasound examination according to BI-RADS classification, based on Pearson's correlation coefficient, we concluded that there is a strong correlation between these two tests (r = 0.743), which is statistically significant (p &lt;0.005). The correlation, in addition to having a strong connection, moves in a positive direction, that is, by increasing the value of BI-RADS of one diagnostic procedure, there is an increase in another.<br><strong>Conclusion:</strong> By analyzing the obtained results, we can conclude that mammography and ultrasound methods of breast examination are complementary methods, which complement each other, and which are not perfect. However, these two methods certainly have their place in breast cancer screening.</p> Mirko Petrić Adnan Šehić Ismira Čatović Copyright (c) 2020 Mirko Petrić, Adnan Šehić, Ismira Čatović 2020-11-07 2020-11-07 11 1 23 29 10.48026/isnn.26373297.2020.11.1.4 The analysis of the subjective image quality of a dental radiogram obtained with a digital and film detector <p><strong>Introduction:</strong> Today film-based technologies are largely abandoned in dental radiology. New technologies based on digital detectors are being adopted. This change is part of the global digitalization of radiological procedures. A person operating the radiological device needs to be educated and well informed about radiological procedures and technologies, as well as to know how the system operates and to be sure about the dose required for the adequate image quality. The awareness of radiation doses received by patients is necessary for the estimation of risk from ionizing radiation.<br><strong>Material and methods:</strong> The aim of this study was to evaluate whether patient doses in intraoral dental radiology affect image quality. The study included subjective analysis of radiological image quality for an intraoral x-ray device with possibility to use both digital and film detector. Subjective assessment of image quality is performed according to criteria taken from the literature and is expressed using the Likert scale, grade 1–5. In order to improve the quality of inferential statistics related ratings to detector quality and image quality were collected, thus introducing two variables: the detector quality index and the technique quality index.<br><strong>Results:</strong> Z-test proportions column shows that the number of grades four given as a contrast score is significantly higher in the RVG detector (65%) compared to the film (40%). There is also a significant difference in the number of given grades five as a rating of the apex preview. The share of grades five in film is 19%, while in RVG it is 42%. It is similar in the evaluation of the preview of the dental canal, where there is also a significant difference in the number of given grades five, so that the share in the film is 11% and in RVG 35%.<br><strong>Conclusion:</strong> Analysis of the subjective quality of the radiological image in devices for intraoral radiography with the possibility of recording using digital and film detectors indicates that the digital detector is superior to film in low contrast resolution, apex and dental canal preview.</p> Ermina Sadiković Adnan Beganović Fuad Julardžija Adnan Šehić Samir Tatarovac Adnan Pezo Copyright (c) 2020 Ermina Sadiković, Adnan Beganović, Fuad Julardžija, Adnan Šehić, Samir Tatarovac, Adnan Pezo 2020-11-07 2020-11-07 11 1 30 34 10.48026/isnn.26373297.2020.11.1.5 The role of hybrid positron computed emission tomography in evaluation of metastatic activity in breast cancer <p><strong>Introduction:</strong> Among the female population, breast cancer is the most commonly diagnosed cancer in the world, and nearly half of women population with breast cancer develop metastatic disease during their lifetime. Breast cancer most often metastazises to the lungs, liver, bones, brain and lymph nodes. 18F-FDG PET/CT can detect metastases that are not visible in other imaging modalities, and with the newly discovered lesions, decision about adequate treatment option can be evaluated.<br><strong>Material and methods:</strong> The examination was conducted as a retrospective descriptive study in May and June of 2019 at the Clinic for Nuclear Medicine and Endocrinology of the University Clinical Center in Sarajevo. It included 100 female patients with the age structure of 33-79 years. The patient's reference diagnosis is breast cancer, with a suspected finding of metastatic activity. A comparison of the sensitivity and specificity of the breast imaging between PET/CT, CT and bone scintigraphy was performed.<br><strong>Results:</strong> PET/CT revealed significantly more positive findings on metastatic activity than other diagnostic imaging modalities, with Mann-Whitney test value of p = 0.01014. In the diagnosis of lungs and liver lesions, PET/CT sensitivity and specificity are 92.59% and 85.37%, respectively, while the statistical parameters for CT are 77.78% for sensitivity and 90.24% for specificity. The PET/CT sensitivity and specificity for bone lesions are 93.55% and 88.89%, respectively, compared to 78.57% and 100% for bone scintigraphy.<br><strong>Conclusion:</strong> Hybrid imaging technique, which integrates PET and CT imaging methods, has considerable advantages over other diagnostic methods in the detection of distant metastases, and based on obtained results, PET/CT may be method of choice in evaluation of metastatic activity in breast cancer.</p> Omar Bataine Sandra Vegar - Zubović Fuad Julardžija Jasmina Bajrović Nusret Salkica Copyright (c) 2020 Omar Bataine, Sandra Vegar - Zubović, Fuad Julardžija, Jasmina Bajrović, Nusret Salkica 2020-11-07 2020-11-07 11 1 35 40 10.48026/isnn.26373297.2020.11.1.6
