摘要
目的探讨婴幼儿锥形束CT(CBCT)检查中,水合氯醛灌肠镇静对其的成功率及图像伪影影响.方法回顾性分析行CBCT检查的1 752例1~6岁患儿资料,根据是否镇静分为镇静组和非镇静组,首次检查非镇静组1 533例,首次检查镇静组共219例,分析首次检查成功率及图像伪影情况.结果镇静组首次检查成功率99.5%(218/219),明显高于非镇静组的90.4%(1 386/1 533),差异有统计学意义(χ^2=20.65,P<0.01).镇静组的图像Ⅰ度伪影和Ⅱ度伪影出现率分别为4.8%(15/314)、0.3%(1/314),明显低于非镇静组的20.1%(327/1630)、12.2%(199/1630),差异有统计学意义(χ^2=81.667,P<0.01).结论在接受CBCT的患儿中,应适度选用水合氯醛灌肠镇静,可以明显有效提高检查的成功率、降低图像的伪影出现率,从而减少患儿的辐射剂量.
Objective To discuss the success rate and image quality in pediatric patients who used chloral hydrate before their cone beam computed tomography exam.Methods 1752 patients aged 1 to 6 were selected for this retrospective study.They were divided into sedated group(219 cases)and non-sedated group(1 533 cases).The success rate and image quality were compared between two groups.Results The sedated group had a higher success rate to non-sedated group:99.5%(218/219)vs.90.4%(1 386/1 533).The motion artifact in sedated group was lower than non-sedated group with I degree:4.8%(15/314)vs.20.1%(327/1 630)and II degree:0.3%(1/314)vs.12.2%(199/1 630).Conclusion Giving chloral hydrate to pediatric patients before their CBCT exam would improve both success rate and image quality,and reduce unnecessary radiation expose.
