To assess operator-, examination-, and patient-related factors, affecting patient movement and re-exposure in cone beam computed tomography (CBCT) examination.
The sample consisted of 248 CBCT examinations in 190 patients video-recorded during examination. Three observers scored the videos; the patient moved or did not move. Operator-, examination-, and patient-related factors were evaluated separately (chi-square test) and by multivariate regression analyses (patient movement and re-exposure as separate outcomes).
The prevalence of movement was 21%. Cotton roll stabilizing patient's jaws, CBCT unit touching patient's hair, and patient's age 15 years or greater were related to movement. Age 15 years or greater had a significant impact on movement (P < .001; odds ratio [OR] 11.0). There were 16 re-exposures (6.4%). Age 15 years or greater, presence of a cotton roll, and field of view (FOV) were related to re-exposure. Use of a large FOV had significant impact on re-exposure (P = .04; OR 5.8).
Operator-, examination-, and patient-related factors may affect patient movement and re-exposure in CBCT examination.
评估影响锥形束计算机断层扫描（CBCT）检查中患者移动及再次照射的操作人员、检查及患者相关因素。
样本包括对190例患者进行的248次CBCT检查，检查过程进行了视频记录。三名观察者对视频进行评分，判断患者是否移动。分别对操作人员、检查及患者相关因素进行评估（卡方检验），并通过多因素回归分析（将患者移动和再次照射作为独立结果）进行分析。
移动发生率为21%。用棉卷稳定患者颌部、CBCT设备接触患者头发以及患者年龄15岁及以上与移动有关。年龄15岁及以上对移动有显著影响（P <.001；比值比[OR] 11.0）。有16次再次照射（6.4%）。年龄15岁及以上、使用棉卷以及视野（FOV）与再次照射有关。使用大视野对再次照射有显著影响（P =.04；OR 5.8）。
操作人员、检查及患者相关因素可能影响CBCT检查中的患者移动及再次照射。
