低剂量CT扫描对儿童肺部病变的诊断与防护价值

Diagnosis and Radioprotection with Low Dose CT Scanningin Child's Lung Disease

摘要: 目的:探讨低剂量CT扫描技术在儿童肺部病变检查中的临床应用与防护价值。方法:对高度怀疑肺部病变的儿童患者28例行常规及低剂量肺部CT扫描,观察比较其对病变的定量及定性诊断的差异及其辐射剂量的差异。结果:与常规剂量CT扫描相比,低剂量CT扫描对病变的定量与定性诊断无明显差异而辐射剂量大幅度下降。结论:低剂量CT扫描技术适用于儿童肺部病变的检查,有利于患儿肺部的辐射防护。

Abstract: Objective: To evaluate low dose CT scanning in detecting child's lung disease and it’s significance in radioprotection.Methods: Conventional and low dose CT scanning were performed in 28 cases of children with suspected lung disease.The accuracy in the lesion detection and characteristic diagnosis were compared and dose difference was analyzed.Results: There were no significant difference between two ways of CT scans in lesion detection and characteristic diagnosis.The radiation dose was greatly decreased in low dose CT scanning.Conclusion: Low dose CT scanning is suitable for examining the lung disease of children and it plays an important role in radioprotection.
