Relationship between image motion artifacts and patients' anxiety, age and gender on Cone Beam Computed Tomography (CBCT) imaging

Abstract

Introduction: Motion Artifacts are a general problem in radiology because the primary principals of radiology are to reduce radiation exposure to patients and to ensure the best image quality. As we know anxiety increases patients' movement and couses more motion artifacts. The aim of this study was to investigate the relationship between image motion artifacts and patients' anxiety, age and gender on Cone Beam Computed Tomography (CBCT) imaging.

Methods: In this descriptive-analytical study, A total of 150 patients (58 mens ;92 females) referred to the radiology department of the tabriz dental faculty selected randomly and with their own consent. The patients filled in STAI-S, STAI-T and MDAS anxiety questionnaires before undergoing CBCT scanning. Patient age and sex were noted on the questionnaires.All Artifacts in axial, coronal and sagittal sections were examined by a radiologist and a dental student. Records were statistically analysed using SPSS (version 24).

Results: There were motion artifact in 18 (%12) patients. The average (standard deviation) age of patients with motion artifacts were 47.00(14.84) and 41.25(1.08) for patiennts with out motion artifacts. The difference was not significant (p-value = 0.08). Motion artifacts were found in 12.07% of men and 11.96% of women. Non- significant relationship were found between the motion artifacts and gender (p-value=0.98). The mean score of state anxiety for patients with motion artifact were 50/83(11/13) and 44/83(8/74) for patients with out motion artifact. That was a significant difference (p-value=0.009). The mean score of trait anxiety for patients with motion artifact were 49/28(12/32) and 44/85(8/15) for patient with out motion artifact. That was a significant difference (p-value=0.045). The mean score of dental anxiety for patients with motion artifact were 12/33(4/08) and 11/56(3/63) for patients with out motion artifact . That was a non-significant difference (p-value=0.41).

Conclusion: In this study There were non-significant relationship between patients' Gender and age with motion artifact. There was a significant relationship between state anxiety and trait anxiety with motion artifacts. But there was no significant relationship between dental anxiety and motion artifacts.
