摘　　要：目的探讨多层螺旋CT低剂量扫描在儿童鼻窦炎中的诊断价值。方法对150例鼻窦炎患儿进行多层螺旋CT扫描,根据扫描剂量分为A组(100 kV/100 mA)、B组(100 kV/25 mA)、C组(100 kV/40 mA),各50例。3组均进行两次扫描,对所得图像进行三维重建后,比较3组的诊断准确率及图像质量。结果3组诊断准确率差异有统计学意义(P<0.05),其中C组的诊断准确率高于A组和B组(均P<0.05)。3组患儿的图像质量评分差异有统计学意义(P<0.05),其中B组和C组的图像质量评分均高于A组(均P<0.05)。结论多层螺旋CT低剂量(100 kV/40 mA)扫描诊断儿童鼻窦炎的价值更高,可为临床诊疗提供影像依据。Objective To explore the diagnosis value of low-dose multi-slice spiral CT in children with sinusitis.Methods A total of 150 children with sinusitis were scanned with multi-slice spiral CT and divided into group A(100 kV/100 mA),group B(100 kV/25 mA)and group C(100 kV/40 mA)according to the scanning dose,with 50 cases in each group.Each group underwent two scans,and the images were obtained via three-dimensional reconstruction prior to the comparison of diagnostic accuracy and image quality among the three groups.Results The three groups showed statistically significant difference in diagnostic accuracy(P<0.05),of which group C exhibited a higher diagnostic accuracy than groups A and B(all P<0.05).The three groups showed statistically significant difference in image quality score(P<0.05),of which groups B and C had higher image quality score than group A(all P<0.05).Conclusion Low-dose(100 kV/40 mA)multi-slice spiral CT scan has higher value in the diagnosis of sinusitis in children,which can provide imaging basis for clinical diagnose and treatment.
