不同剂量多排螺旋CT尿路成像技术对尿路病变诊断效能的对比

目的:探讨不同剂量多排螺旋CT尿路成像技术(CTU)对尿路病变的诊断价值。方法:选择2015年1月至2016年12月在我院行CTU检查的尿路病变患者60例作为研究对象,按照随机数字表法分为3组:160mA管电流组(I组)、120mA管电流组(U组)和80mA管电流组(111组)。所有患者均采取对应的管电流CTU检查。对比分析3组患者尿路病变的诊断效能及3组患者CTU成像效果评分、碘对比剂用量及辐射有效剂量。结果:川组患者碘对比剂用量、辐射有效剂量较I组、H组低,且H组较I组低,差异有统计学意义(P<0.05)。3组患者CTU成像效果评分差异无统计学意义。结论:低剂量(80mA管电...

Objective:To explore the diagnostic value of low dose multi detector computed tomography urography(CTU)in patients with urinary tract diseases.Methods:Sixty patients who were treated with CTU from January2015to December2016were included in this study.All patients were divided into three groups according to the random number method.GroupⅠ(160mA tube current),groupⅡ(120mA tube current)and groupⅢ(80mA tube current),the selected patients were taken to the corresponding tube current CTU.The diagnostic efficacy of three groups of uropathy was analyzed,and the three groups of CTU imaging results,iodine contrast agent dosage and radiation dose of the situation were compared.Results:The dose of iodine contrast agent and the effective dose of radiation in groupⅢwere lower than those in groupⅠand groupⅡ,and the dose of radiation and dose of iodine contrast agent in groupⅡwere lower than those in groupⅠ(P<0.05).The difference of CTU imaging scores between t
