Summary: An increasing demand for US examinations has led to an overwork of radiologists, who are in short supply on the labour market. A possible solution to the problem of shortage and reduction of the workload of radiologists is the education of radiologic technologists for the profession of sonographer. Aim: The objective of this thesis is to investigate the possibility of radiologic technologists working as sonographers and to define the necessary conditions for the introduction of this new field of work. The primary goal of the conducted research is to determine whether there is an interest among radiologic technologists in their third year of graduate studies at the University of Split, University Department of Health Studies and Master of Radiologic Technology to work on sonography. Subjects and methods: By reviewing the available literature and already conducted research, an effort was made to investigate whether there are significant differences between the results of the work of radiologists and sonographers, and whether waiting lists for US examinations would be reduced by the introduction of sonographers. The measuring instrument for this research was a newly constructed questionnaire. The data collection method was an online survey that was conducted in June 2022. Results: From the results of the conducted survey, it is evident that there is a great interest among radiologic technologists who attend the third year of radiological technology graduate studies in Split and who have already completed their master's degrees at the same university. Furthermore, they are willing to allocate time and financial resources for further sonographer training. Further research is needed in order to have an insight into the opinion of all radiological technologists in the Republic of Croatia. The literature and research results point to the conclusion that US examinations performed by sonographers do not differ significantly in quality and accuracy from US examinations performed by radiologists. Conclusion: The growing technological progress has contributed to the wide application of US devices and the increasing demands for quality workforce to perform US examinations. Sonographers are an ideal solution for the shortage of radiologists and for increasing the effectiveness and efficiency of diagnostic US.
