Nurses working in surgical and therapeutic departments assessed their knowledge differently. Although a majority of respondents in both profiles correctly identified medical imaging procedures involving ionizing radiation and acknowledged the risks associated with ionizing radiation for pregnant women, there was still a lack of knowledge regarding contraindications to magnetic resonance imaging. Most nurses agreed that it was important to have basic knowledge of medical imaging procedures, although many had not participated in relevant training or seminars, indicating a need for continued education in this area.Surgical nurses demonstrated a better level of knowledge and perception of medical imaging than therapeutic nurses. Nevertheless, in general, all respondents rated their knowledge as inadequate.
