摘要
目的:研究多层螺旋CT儿童鼻窦低剂量扫描的临床应用。方法:选取80例需鼻窦扫描患儿,随机分成低剂量组和常规组,分别进行低剂量和常规剂量CT扫描,评价图像质量。结果:低剂量组DLP值明显低于常规组(P<0.05),低剂量组图像质量评分略低于常规组(P>0.05)。结论:低剂量扫描能够在不影响临床诊断的同时,降低患儿辐射剂量。
Objective：The clinical application of multi-slice spiral CT in nasal sinuses of children with low dose was studied. Methods： 80 patients were randomly divided into low dose group and routine group respectively. The image quality was evaluated by low dose and conventional dose of CT scanning. Results：Low dose group DLP was signiifcantly lower than the conventional group （P〈0.05）, image quality of low dose group score was slightly lower than the conventional group （P〉0.05）. Conclusion：Low dose scanning didn’t affect the clinical diagnosis, moreover, reduce the radiation dose.
