Patient's knowledge regarding radiation exposure from various imaging modalities: a pilot study.

This article focuses on assessing patients' knowledge about ionising radiation used in diagnostic imaging and the adequacy of information provided by referring physicians. Conducted as a cross-sectional survey at University Hospital Merkur in Zagreb, Croatia, the study involved 374 patients undergoing various imaging procedures, revealing that while most patients were aware that some radiological exams involve ionising radiation, detailed understanding—such as recognizing MRI as non-ionising or identifying the lowest radiation dose modalities—was limited and correlated with educational level. The study found no significant difference in knowledge between patients who received explanations from physicians and those who did not, suggesting gaps in both patient education and healthcare provider communication. The authors recommend enhanced educational efforts for both patients and physicians to improve awareness of radiation exposure and associated health risks.
