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

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.
