不同低剂量多层螺旋CT扫描在儿童头部检查中获得的图像质量比较
|
摘要
目的比较不同低剂量多层螺旋CT扫描在儿童头部检查中获得的图像质量。方法选择2015年1月~2016年12月至我院进行多层螺旋CT检查的患儿50例进行临床研究,使用随机数字法将患儿分为A、B两组,各25例,所有患儿均给予头部多层螺旋CT检查。A组患儿给予120 k V、150 mAs低剂量进行检测,B组患儿予以90 k V、150 mAs低剂量进行检测。对所有患儿CT片质量进行评价,并统计患儿所承受的辐射值。结果 A组患儿CT片优秀92.00%,高于B组84.00%,但无统计学差异(P>0.05),A组患儿平均辐射(32.44±5.18)mGy,明显高于B组(27.18±4.62)mGy,且统计学差异显著(P<0.001)。结论 90 k V、150 mAs低剂量螺旋CT检查既能够保证拍片质量,同时减少患儿辐射值。
Objective To compare the image quality obtained by children's head examination with different low doses of multi-slice spiral CT scan.Methods 50 children patients with multi-slice spiral CT examination from January 2015 to December 2016 in our hospital were selected for clinical study.The random number method was used to divide the children into group A and group B,with 25 cases in each group.All patients were given multi-slice spiral CT examination of the head.Children in group A were given low doses of 120 kV and 150 mAs for testing.Children in group B were given low doses of 90 kV and 150 mAs for testing.The quality of CT scans was evaluated in all children patients and the radiation values of the children patients were statistically analyzed.Results The excellent CT scan in group A was 92.00%,which was higher than that of 84.00% in group B,but there was no statistical difference(P >0.05).The average radiation of(32.44±5.18) mGy in group A was significantly higher than that of(27.18±4.62) mGy in group B,and the differences were statistically significant(P<0.001).Conclusion Low-dose spiral CT examination with 90 kV and 150 m As can not only guarantee the image quality but also reduce the radiation value of the children.
