目的：探讨64排螺旋CT低剂量扫描技术在颅脑血肿治疗中的临床应用价值。方法对120例颅脑血肿患者首次行常规剂量CT检查，复查分为常规剂量组和低剂量组（每组60人）。分析低剂量组患者首次检查和复查的辐射剂量。分析常规剂量组和低剂量组复查图像是否满足诊断要求。结果与常规剂量组相比，低剂量组CT图像质量良好，图像噪声略增强，解剖结构清晰，能满足诊断要求，且患者辐射剂量明显下降。结论螺旋CT低剂量扫描技术适用于颅脑血肿治疗后复查，特别是对于多次复查的患者，有利于降低辐射剂量，减少辐射损害。

Objective To investigate the clinical application value of low-dose scanning technology of 64-row spiral CT in the treatment of cerebral hematoma.Methods 120 patients with cerebral hematoma were examined initially by CT with conventional dose. Then these patients were divided into conventional dose group (60 cases) and low dose group (60 cases) during the reexamination process. The radiation doses of initial examination and reexamination of patients in low dose group were analyzed. The analysis about whether the reexamination images of patients in both of the two groups can meet the diagnostic requirements was also conducted.Results Compared with the reexamination images of patients in conventional dose group, the reexamination images of patients in low dose group with higher quality and stronger noise can display the anatomical structures clearly, which indicated that low dose images could satisfy the diagnostic requirements. The exposure doses of patients in low dose group were also significantly lower than those of patients in conventional dose group.Conclusion Low-dose scanning technology of spiral CT which can reduce the exposure dose and the radiation damage is suitable for the reexamination of cerebral hematoma, especially for the patients who need multiple reexaminations.
