摘要目的比较标准5min延迟的排泄相(delayed excretory phase,EP)与静脉注射利尿药后增强CT延迟60s的尿路上皮相(urothelial phase,UP)在上尿路肿瘤的高危人群中的检出价值。材料与方法此项研究已获伦理审查委员会批准。77例确诊或高危尿路上皮恶性肿瘤病人共行80次CT尿路检查。静脉注射利尿剂后60s(UP)及5min(EP)后分别行CT尿路成像扫描。2名有经验的腹部放射科医生间隔1个月以上分别独立分析两期图像以消除记忆偏差。
Abstract Objective To compare the diagnostic value of standard 5 min delayed excretory phase (EP) with that of intravenous diuretic in enhancing the detection of urothelial phase (UP) delayed 60 s in high-risk groups of upper urinary tract tumors. Materials and Methods The study was approved by the Ethics Review Board. 77 cases of patients diagnosed or at high risk of urothelial cancer 80 urinary tract urinary tract tests. Intravenous diuretics after 60s (UP) and 5min (EP) were performed CT urography scan. Two experienced abdominal radiologists independently analyzed two images at intervals of more than 1 month to eliminate memory bias.
