ABSTRACT
Objective@#This study examined whether the changes in reimbursement coverage of brain magnetic resonance image (MRI) affected practice for patients who visited the emergency department with dizziness as the chief complaint. @*Methods@#Among the 5,423 patients who visited the emergency department for dizziness in 2017, 2019, and 2021, 4,497 patients were included in the study retrospectively and investigated by brain diffusion-weighted MRI and the presence of cerebral infarction on brain diffusion-weighted MRI. This study examined whether there was a significant difference before and after the change. @*Results@#In 2017, 2019, and 2021, 1,489, 1,570, and 1,438 patients with dizziness visited the emergency department, respectively. The number of patients who underwent a brain MRI scan gradually increased from 237 (15.9%) in 2017 to 628 (40.0%) in 2019 and 948 (65.9%) in 2021 (P<0.001). The number of positive findings on brain MRI scan increased gradually from 30 patients (2.0%) in 2017 to 47 patients (3.0%) in 2019 and 53 patients (3.7%) in 2021 (P=0.025). The ratio of positive findings of brain MRI scans to the number of patients who underwent brain MRI scans decreased gradually to 12.7% in 2017, 7.5% in 2019, and 5.6% in 2021 (P=0.001). @*Conclusion@#The changes in the reimbursement coverage of brain MRI affect the number of brain MRI scans and the detection of cerebral infarction.
