Population ageing increased demand for diagnostic imaging. This study was to explore the elderly aged over 65 of radiological medical utilizations and influence factors. Methods: We used data from 2010 National Health Insurance Research Database and cross-sectional study. All inpatients over the age of 65 with a total of 531,850 people were enrolled. In addition to descriptive analyses of radiological medical utilizations, we used negative binominal regression to analysis the influence factors of 65 years and over aged inpatients radiological medical utilizations. Results: In 2010, the radiological examination of elderly inpatients aged 65+, chest X-ray (66.9%) used the largest number, followed by CT (23.8%), abdominal X-ray (23.7%), other X-ray (14.6%), and MRI (8.5%). The age group in the most used chest X-ray and CT is 75-79 years, abdominal X-ray is 80-84 years, other X-ray and MRI is 70-74 years. Once hospitalized is 62.4%, and greater than or equal to twice hospitalized is 37.6%. In using medical imaging tool, the proportion of inpatients for once hospitalized and greater than or equal to twice hospitalized are 61.8% and 90.8%. In using medical imaging tool, the ratio of inpatients for once hospitalized and greater than or equal to twice hospitalized are 61.8% and 90.8%. Negative binomial regression analysis of radiological examination in hospitalized patients over 65 years, found that utilization of chest X-ray and abdominal X-rays increased with age (reference group 65-69 years); before age 95 years, CT utilization increased with age; after age 80 years, the utilization of other X-ray and MRI decreased with age. Males received significant more chest X-ray, abdominal X-ray and CT than females; males received less other X-ray and MRI than females. Ischemic stroke inpatients have a higher radiological medical utilization in chest X-ray, abdominal X-ray, other X-ray, CT and MRI than non-ischemic stroke inpatients. Hemorrhagic stroke inpatients have a higher radiological medical utilization in chest X-ray, abdominal X-ray, CT and MRI than non-hemorrhagic stroke inpatients except other X-ray. Conclusion: Inpatients older age and male over 65 years old have higher possibility of radiological examination in chest X-ray, abdominal X-ray and CT. Ischemic and hemorrhagic stroke inpatients have higher radiological medical utilization than non-stroke inpatients. Increasing age, elderly patients' radiological medical utilization increased, and the workload of radiological department increased. We hope the results provide references to policy decision-making. Stroke increased not only disability, but also the long-term costs of health care and radiological medical utilization. In response to Taiwan's population ageing, appropriate emphasis on stroke prevention and health care advocate, in order to reduce the future burden on society.
