摘要
目的探讨螺旋CT低剂量一体化扫描在多发外伤中可行性。资料与方法60例外伤患者随机分为3组,第1组为单个程序进行多发外伤的扫描,第2组为一体化程序扫描,第3组为低剂量一体化扫描方式,对3组图像进行对比分析。结果第3组比第2组下降了67.3 mGy,与标准剂量扫描比较,低剂量扫描放射剂量下降57%,两者差异有统计学意义(P<0.05),第3组与第2组图像质量比较无明显差异,低剂量螺旋CT图像对疾病的诊治无影响。结论螺旋CT低剂量一体化扫描在多发外伤中是可行的,比传统CT扫描减少受检者的辐射剂量,又为抢救病人节约更多的时间。
Objective To study the feasibility of low-dose and integrative spiral CT examination for various traumatism. Methods Sixty cases traumatism were randomized to dispart 3 groups,using single program in group A, using integrative programs group B and using low-dose and integrative program in group C, then comparisons of the qualities of the films among three groups were curied out, Results The value of CTDIvol was 67.3 mGy lower in group C than group B,compared with the standard-dose scan. The radiation dose was decreased by 57% in the low-dose scan with significant difference（P 〈 0.05） , however the quality of images was not different. Conclusion The low-dose and integrative spiral CT examination for various traumatism was feasible. The dose reduction scan mode could reduce more radiation dose than the conventional dose,and economize time for salving sufferers.
