Analysis of the characteristics of traffic trauma
Introduction: It is estimated that an average of 1,308 people die in traffic accidents in the world every day. Traffic accidents are caused by factors of the road, vehicles and the human factor, which occur alone or in combination with other factors in over 90% of cases. Material and methods: The retrospective systematic research included all cases of traffic trauma that were brought to the admission surgical outpatient clinic in the Clinical Hospital Center Kosovska Mitrovica in the period from January 2020 to December 2022. Results: In the observed period, 126 patients were registered. The age of the respondents differs statistically according to gender (p=0.030), and the highest frequency is male (81.8%) in the working population (18-59 years). The age of the subjects showed no statistical association with the types of injuries in traffic trauma (p=0.151). Friday and Saturday are the days with the highest risk (25.3% of injuries), and Sunday is the day with the least number of injuries (3.6%). The lowest number of injuries was recorded from January to May (n=12, 9.5%), and the highest was in the period August to October (n=54, 42.9%). A male patient, 20 years old, an alcoholic, required urgent surgical treatment (splenectomy) due to abdominal injuries. Alcoholism and the age of the subjects did not show statistical significance (p=0.495), and 24.6% of patients had a diagnosis of alcoholism. The age of the subjects showed a statistical association with hospitalization (p=0.004), male gender and age between 18-59 years. Only 2 patients required transport to a highly specialized facility. The fatal outcome showed a statistically significant correlation with the age of the respondent (p=0.016), there was only one patient (between 12-18 hours), a female, 85 years old as a passenger of a motor vehicle. Conclusion: The results of our study indicate a statistically significantly more frequent injury and hospitalization of male patients, that Friday and Saturday are the days of greatest risk and that the fatal outcome occurs in extremely elderly patients. Our findings favour the need to raise public awareness through the media, public actions and forums.

Anatomical variants of circle of Willis
Introduction: The circle of Willis is the major source of collateral blood flow between the carotid and vertebrobasilar system. Its potential depends on the presence and size of arteries that vary greatly among normal individuals and therefore their adequate observation by a radiologist is necessary. Aim: Determine the type of the circle of Willis and their frequency. Determine the type, frequency and localization of anatomical variants of arteries, as well as their average diameter. Compare these variables according to the age and gender of the examinees. Material and methods: A retrospective study was performed at the Center for Radiology of the Clinical Center Nis during 2017. All subjects underwent CT or MR angiography according to a standard endocranial protocol. The anterior and posterior parts of the circle were specially observed, with an emphasis on the presence or absence of anatomical variants of the arteries, with the measurement of their diameter. The obtained data were classified into variants of the front or rear part of the ring as well as the type of ring according to integrity. The frequency of these variables and their comparison by sex and age were measured. Results: The research included 92 examinees. According to the configuration of the Willis arterial ring, the adult type was the most often represented (71.7%). The most common type in terms of integrity was partially complete. The most common anatomical variants obtained in our work was aplasia of AcoA (27.2%) and aplasia of one or both PCoA (21%). PcoA hypoplasia was occured in women with a frequency of 13.5% while in men it was not present. Conclusion: Adequate understanding of the morphology of the circle of Willis by radiological methods is a good guide for neurosurgical and radiological intervention procedures. In this way, potentially significant neurological complications and the risk of morbidity and mortality could be reduced.

The role of computerized tomographic angiography in the diagnosis of pathologically modified renal arteries
Introduction: The most common causes of renal artery disease are stenosis, as a consequence of atherosclerosis and fibromuscular dysplasia. Computed tomographic (CT) angiography is a non-invasive method, which enables visualization of vascular structures and walls of blood vessels, as well as morphology of the renal parenchyma. Objective: To determine the importance of CT angiography in detecting the cause and degree of renal arterial disease. Methods: A total of 45 patients were included in the cross-sectional study conducted from March 2017 to March 2019 in the KBC DR Dragiša Mišović-Dedinje, Belgrade, Serbia. Criteria for inclusion were suspicion of secondary arterial hypertension, patients in preparation for kidney transplantation and in the follow-up period after transplantation, as well as patients with suspected traumatic lesions. We analyzed the causes of the disease, the morphology of the blood vessel wall, the percentage of stenosis, and the renal parenchyma. Results: The most common causes of renal arterial disease are atherosclerosis, which was found in 33 (73%) patients, renal artery aneurysm was found in 5 (11%) subjects, fibromuscular dysplasia in 4 (8.9%) and trauma in 1 (2) , 3%) of the patient. There were 10 (22.2%) patients with a significant (average 80 ± 14.5%) degree of stenosis. The sensitivity of CT angiography in the detection of atherosclerotic changes in the renal arteries was 87.9%, while the sensitivity of CT angiography in the detection of fibromuscular dysplasia was 75%. A statistically significant correlation was found between atherosclerotic stenosis of the renal arteries and a positive CTA finding (p = 0.0002). Conclusion: CT angiography is an important method of visualization and quantification of pathological changes in the renal arteries.

Errors and artifacts on radiographs
Introduction: The process of recording a patient includes a procedure with several separate segments during work that together provide the imaging to be obtained for adequate radiological analysis. Throughout the process, it is possible to experience errors that create artifacts on X-rays which ultimately results in an inadequate recording that is not for valid analysis. Aim: Determine the total number of radiological films that are not for valid analysis. Sort out and analyze errors in radiographs according to the work process. Provide recommendations for improving the quality in the process of recording the patient. Material and methods: A prospective study was conducted at the Radiology Clinic of the Clinical Hospital Center Pristina-Gracanica, for two calendar years. All films that are not for valid analysis were considered. The radiological procedure of patient imaging was broken down into logical segments so that possible errors could be observed. We have summarized the causes of the artifacts in five appropriate groups (errors made by the recording technique, during the acquisition of the image, caused by the object of recording, during the processing of films in an automated machine and improper handling of films). Results: The total amount of used X-ray films is 32600 pieces, of which 242 (0.74%) were errors and artifacts. The most common format of a film with an error or artifact was 30x40 cm. A frequency of errors according to the cause of the occurrence is classified into appropriate groups. The largest number was in a group 1 - 155 (64.04%), in a group 2 - 3 (1.24%), in a group 3 - 13 (5.37%), in a group 4 - 67 (27.69%), and in a group 5 - 4 (1.66%). Conclusion: In the proper systematization of all observed errors and artifacts of X-ray film, it allows us to realise the place of error during the whole process of recording and processing of the film. We hereby wish to propose their elimination and improve the quality of the radiology department.
