Résumé

Objective: To determine the level of knowledge of patients about radiological examinations and its influence on their level of anxiety within the radiology department of the CHR Hassan II Agadir. Methodology: This is a descriptive study with an analytical purpose. A total of 107 patients participated in this study. Of these, 36 patients underwent standard X-rays, 36 patients under-went CT scans, and 35 patients underwent MRIs. Data were collected using three questionnaires administered to patients according to their host unit. Each of these questionnaires was divided into three parts (sociodemographic data, knowledge of the radiological examination and level of anxiety). Results: Young adults predominate among the participants, with a slight majority of women. Knowledge scores were similar for each type of examination: standard radiology (65.17), CT (63.49), and MRI (61.52). Anxiety, as measured by the STAI Y-6 scale, was higher for MRI (18.14) compared to standard radiology (16.83) and CT (15.92). Knowledge and anxiety scores show a significant correlation with age and education level, but do not show a link with gender, except for anxiety in standard radiology and MRI, where women had higher levels. A moderate to low inverse correlation was observed between the level of knowledge and the level of anxiety for each type of examination, (r = -0.397; p = 0.016) for standard radiology, (r = -0.324; p = 0.035) for CT and (r = -0.098; p = 0.043) for MRI, suggesting that better knowledge about the radiological examination reduces anxiety. Conclusion: The study reveals a significant correlation between patients' level of knowledge about radiological examinations and their level of preprocedural anxiety. Patients who are bet-ter informed generally have less anxiety, although there are variations depending on the type of examination. This research highlights the importance of preprocedural education in reducing anxiety, offering practical guidance for practitioners while identifying avenues for future stud-ies focused on educational interventions and long-term outcomes.
