摘　　要：目的:分析CT低剂量扫描在泌尿系统结石治疗中的应用价值。方法:将我院近年来(2020年1月至2022年1月)收治的泌尿系统结石患者共50例分为观察组(低剂量,25例)和对照组(常规剂量,25例),比较两组在不同剂量检查下的疾病检出率、辐射剂量、CT图像质量。结果:分析可见,观察组与对照组之间的肾脏结石、输尿管上段、中段及下段结石检出率均无统计学意义(P>0.05);分析观察组与对照组之间的辐射剂量,包括DLP、CTDlvol剂量,观察组更低,对比分析有统计学意义(P<0.05);两组CT图像质量检查可见,观察组与对照组均无统计学意义(P>0.05)。结论:在泌尿系统结石诊断中对患者用CT低剂量扫描可在保证诊断准确率及图像质量的情况下降低辐射剂量,减轻对人体的损伤,对泌尿系结石的检查价值较高,值得临床广泛应用。Objective:To analyze the value of low-dose CT scanning in the treatment of urolithiasis.Methods:A total of 50 patients with urolithiasis admitted to our hospital in recent years(2020.1-2022.1)were divided into observation group(low dose,25 cases)and control group(conventional dose,25 cases).The disease detection rate,radiation dose and CT image quality of the two groups under different doses were compared.Results:There was no statistical significance in the detection rates of renal calculi,upper,middle and lower ureteral calculi between the observation group and the control group(P>0.05).The radiation dose between the observation group and the control group,including the dose of DLP and CTDlvol,was lower in the observation group,with statistical significance(P<0.05).CT image quality examination showed that there was no statistical significance in the observation group and the control group(P>0.05).Conclusion:Low-dose CT scan in the diagnosis of urolithiasis can reduce the radiation dose and reduce the damage to human body under the condition of ensuring the diagnostic accuracy and image quality.It is of high value in the examination of urolithiasis and worthy of widespread clinical application.
