| 目的 探讨低剂量CT扫描技术在婴幼儿颅脑病变检查中的临床应用与防护价值。方法 对高度怀疑颅内病变的婴幼儿患者36例行常规及低剂量颅脑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扫描技术也适用于婴幼儿颅脑病变的检查,有利于患儿颅脑部的辐射防护。 |

| 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. |
