Purpose: To analyze the evolution of various radiological examinations requested for patients admitted to the emergency department (ED) of a University Hospital. Materials and Methods: We analyzed data on MRI, CT scan, Ultrasound (US), and X-ray activities, along with ED patient admissions over a ten-year period from 2014 to 2023. The patient data for each modality, categorized by age and sex, were extracted from the Radiological Information System database. Results: The number of patients undergoing radiological examinations increased from 35,532 in 2014 to 44,592 in 2023, marking a 25.9% increase, while the number of ED admissions rose from 71,776 to 103,456, a 44.1% increase. The ratio of radiological examinations to ED admissions decreased from 49.5% in 2014 to 43.1% in 2023. Over the study period, the number of patients receiving MRI and CT scans increased by 80.4% and 105.8%, respectively. The number of patients undergoing ultrasound remained relatively stable, with 2,616 in 2014 and 2,432 in 2023. In contrast, the number of X-ray patients decreased by 33.1% from 22,236 in 2014 to 14,847 in 2020 but rebounded to 20,492 in 2023. Male patients more frequently underwent CT (51.7%) and X-ray examinations (53.3%). Conclusion: This study highlights a significant increase in radiological activity within the emergency department, especially in CT scans and MRI usage over the ten-year period while ultrasound examinations stayed flat, accompanied by a decline in the ratio of radiological examinations to ED admissions.
