Investigation of the repetition rate of scanning due to motion artifacts in cone-beam computed tomography: a retrospective study

Abstract

Abstract Objective: The objective of this retrospective study was to investigate the incidence of repeated cone-beam computed tomography scans due to motion artifacts in a Turkish subpopulation. Materials and methods: A total of 6364 patients' cone-beam computed tomography data were analyzed retrospectively to identify repeated scans due to motion artifacts. Patients were divided into eight age groups: <10 years, 10-20 years, 20-30 years, 30-40 years, 40-50 years, 50-60 years, 60-70 years, and >70 years. The Chi-Square test was applied to evaluate the repetition rate of scans by age and gender groups. Statistical significance was set at p < 0.05. Results: Repeated scans due to motion artifacts were observed in 1.96% of the patients. The repetition rate of scans was significantly higher in males than in females (p=0.006). Furthermore, the repetition rate of scans was significantly higher in patients <10 years old compared to the other age groups. However, there was no significant difference in the repetition rate of scans due to motion artifacts among the other age groups (p > 0.05). Conclusions: The present findings suggest that patient age and gender are associated with repeated cone-beam computed tomography scans due to motion artifacts. Males and children under the age of 10 had more common repeated scans due to motion artifacts.
