摘　　要：目的:研究16层螺旋CT低剂量扫描在活动性继发性肺结核复查中的检查效果。材料与方法:选取130例活动性继发性肺结核病人为研究对象,对130例患者行常规扫描后再行低剂量扫描。比较常规剂量组和低剂量组CT扫描的效果及使用剂量。结果:两组扫描图像质量比较无统计学差异(P>0.05);两组薄层重建图像质量比较无统计学差异(P>0.05);两组扫描影像学、薄层重建影像学比较,差异无统计学意义(P>0.05)。观察组ED、DLP和CTDIvol等指标明显低于对照组(P<0.01)。即观察组扫描辐射剂量显著低于对照组(P<0.01)。结论:螺旋CT低剂量扫描用于活动性继发性肺结核的复查,可以获得与常规剂量接近的检查效果,并可有效减少CT扫描中的辐射剂量。因此提高了肺结核复查的安全性,节约了检查成本。Purpose： To study detection effect of 16 spiral CT with low dose scanning in active pulmonary tuberculo- sis. Materials and Methods： 130 Cases of active pulmonary tuberculosis patients were selected as the object of study, and 130 patients were treated by conventional scanning and then low dose scanning. CT scanning effect and dose of conventional dose group and low dose group were compared. Results： No significant differences between scan image quality of the two group were found （ P 〉 0.05 ） ; and no significant differences were found between thin slice reconstruction image quality of the two groups （P 〉0. 05） ; The scanning imaging, thin slice reconstruction image of two groups were of no significant difference （ P 〉 0. 05 ）. The observation group ED, DLP and CTDIvol were significantly lower than those in the control group （ P 〈 0. 01 ）. The observation group＇s scanning radiation dose was significantly lower than the control group （P 〈 0. 01 ）. Conclusion： Low dose spiral CT for the review of active pulmonary tuberculosis, can obtaining inspection results like conventional dose close, and effectively reduce the radiation dose in CT scanning. Therefore, to improve the security of pulmonary tuberculosis review, save examination cost.
