低剂量CT扫描在成人继发性肺结核中的应用研究
|
摘要
目的:探讨CT低剂量扫描在成人肺结核复查随访中的应用价值。方法:收治复查的继发性肺结核患者800例,随机分成单排螺旋CT组、6排螺旋CT组、16排螺旋CT组和GE64排螺旋CT组,比较检查结果。结果:扫描图像质量差异无明显统计学意义(P>0.05),使用单排、6排、16排CT和64排CT扫描患者接受的剂量差异无明显统计学意义(P>0.05)。使用低剂量扫描,降低了60%~80%,患者接受的容积CT剂量指数明显低于常规扫描。结论:低剂量CT扫描可以显著降低辐射量,对诊断报告无显著性影响。
Objective:To explore the application value of low-dose CT scanning in the follow-up of adult pulmonary tuberculosis.Methods:800 patients with secondary pulmonary tuberculosis and follow-up were selected.They were randomly divided into the single row spiral CT group,the 6 row spiral CT group,the 16 row spiral CT group and the GE64 row spiral CT group.We compared the examination results.Results:There was no significant difference in the quality of the scanned image(P>0.05).There was no significant difference in the acceptable dose of patients with the single row spiral CT,6 row spiral CT,16 row spiral CT and 64 row spiral CT.Using a low dose scan,the reduction was 60% to 80%,and the volume CT dose index of patients was significantly lower than that of conventional scan.Conclusion:Low dose CT scanning can significantly reduce the amount of radiation.There was no significant impact on the diagnostic report.
