摘　　要：目的:探究自动毫安技术MSCT低剂量扫描在泌尿系结石诊断中的应用价值。方法:选取2016年1月-2018年1月在本院诊治的80例泌尿系结石患者为观察对象,分别采用自动毫安技术MSCT低剂量扫描及常规剂量扫描,比较两种剂量扫描的图像质量、图像噪声、CT辐射剂量及结石诊断情况等。结果:常规剂量与自动毫安技术低剂量扫描结石分布、结石直径、图像质量及诊断准确率比较,差异均无统计学意义(P>0.05)。自动毫安技术低剂量扫描扫描管电流平均为(96.5±18.3)m A,低于常规剂量扫描的(242.6±22.1)m A,图像噪声高于常规剂量扫描,容积CT剂量指数低于常规剂量扫描,差异均有统计学意义(P<0.05)。结论:泌尿系结石诊断中,自动毫安技术MSCT低剂量扫描可满足临床诊断需求,且能极大地降低辐射剂量,安全可行,值得提倡推广。Objective：To explore the application value of auto-milliampere technique MSCT low-dose scan in urinary calculus.Method：A total of 80 patients with urinary calculus in our hospital from January 2016 to January 2018 were selected as the observation objects.They were taken auto-milliampere technique MSCT lowdose scan and the routine-dose scan.The image quality,image noise,CT radiation dose and diagnosis of urinary calculus were compared between two scan modes.Result：There were no significant differences in the distribution of urinary calculus,diameter of urinary calculus,image quality and diagnostic accuracy between two scan modes（P〉0.05）.The average of tube current in the auto-milliampere technique MSCT low-dose scan（96.5±18.3）m A was significantly lower than that in the routine-dose scan（242.6±22.1）m A,the image noise in the automilliampere technique MSCT low-dose scan was higher than that in the routine-dose scan,CT dose index volume in the auto-milliampere technique MSCT low-dose scan was lower than that in the routine-dose scan,the differences were statistically significant（P〈0.05）.Conclusion：In the diagnosis of urinary calculus,the technology application of auto-milliampere technique MSCT low-dose scan can meet the needs of clinical diagnosis and greatly reduce the radiation dose.And it is safe and feasible,worth of promoting and popularizing.
