【Abstract】 Objective To evaluate low dose CT scanning in detecting infant and child’s intracranial disease and its significance in radioprotection. Methods Conventional and low dose CT scanning were performed in 36 cases of infants and children with suspected cranial 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 intracranial lesions of infants and children and it plays an important role in radioprotection.更多还原
