AB  - Breast cancer is the most frequent malignant neoplasm affecting the female population. In order to reduce its morbidity and mortality rate, a mammography screening campaign has been established in both entities of Bosnia and Herzegovina. In this paper, a brief survey is given on the mammography screening practice in the Republic of Srpska. As an illustration, results of measurements of technical parameters, including mean glandular dose, for 31 mammography units are presented. Large fluctuations in dose among different measuring sites were found, unacceptable not only from the standpoint of mammography screening, but in clinical mammography as a whole. Subsequently, a series of quality control tests and corrective measures throughout the mammography imaging chain are proposed, in line with international guidelines and newly promulgated national legislation. Dose optimisation and image quality improvement are the first and foremost goals to be achieved in order to setup a successful mammography screening program.

AB  - Mammography is the method of choice for early detection of breast cancer. In Serbia, mammography is performed only clinically, although there is a plan to introduce mammography as a screening method. Currently, there are 60 mammographic units in practice, resulting in 70 000 mammographies annually. The survey was conducted in order to investigate mammographic practice in Serbia, identify weak points and suggest appropriate corrective measures. Basic technical parameters of the X-ray tube and generator, processing, image quality, and patient doses in 20 mammographic units were studied. The survey demonstrated considerable variations in technical parameters that affect image quality, and patients doses. Patient dose levels, in terms of the mean glandular dose, were fairly consistent with current European reference levels: 1.8 (0.40-4.3) mGy. However, due to inappropriate image receptors, image processing and viewing conditions and automatic exposure control adjustment, suboptimal image quality was a common finding. Simple improvements of the radiographic technique and maintenance procedure, along with the rigid implementation of the quality control procedure and training of the operating staff, would improve the performance levels of mammographic practice in Serbia, i.e. result in the production of high quality images with a reasonably low radiation risk to patients.

AB  - Hysterosalpingography is an important diagnostic method for the evaluation of the female re productive tract involving the exposure of patients to ionizing radiation The irradiation of ovaries is unavoidable and radiation exposure of the patient and the associated radiological risk for the foetus and born child during the period of growth should be considered, as well The purpose of this work is to evaluate organ and patient doses and radiation risks during hysterosalpingography procedures performed in a dedicated gynecological hospital The entrance surface air kerma was measured for a total of 31 patients during hvsterosalpingography Based on the results obtained, the radiogenic risk for hereditary effects and cancer induction was estimated The patient dose levels are in the range of 3-15 mGy, with a median value of 10 mGy, in terms of entrance surface air kerma Estimated median ovarian and uterus doses are 1 7 and 2 3 mGy, respectively The risk for fatal cancer and hereditary effects is estimated to be 5 5 10(-5) and 3 4 10(-6), respectively Although low compared to the natural incidence of genetic effects and cancer, it can be elevated in cases of prolonged or repeated procedures or procedures where the non-optimized protocol is used
