We assessed usefulness of combination of oral administration of both 400 ml of water and 250 ml of negative gastrointestinal contrast (Bothdel: manganese chloride tetra hydrate)to improve image quality , visibility of ureter, and diagnostic ability in MR urography.Magnetic resonance Urography (MRU) was performed in 20 patients with known or suspected urological disease. After precontrast MRU was obtained, postcontrast MRU was obtained 30 minutes after administration of Bothdel and water. Image assessment was based on contrast effect, image effect and opacification score as well as diagnostic ability. Statistical analysis was performed with the Wilcoxon signed rank test. There were statistically significant improvements not only in contrast, image effect and opacification score but also diagnostic ability between pre and post administration images.

我们评估了联合口服400ml水和250ml胃肠道阴性造影剂（Bothdel：四水合氯化锰）对改善图像质量、输尿管可见性和MR尿路造影诊断能力的有效性。对20例已知或怀疑泌尿系统疾病的患者进行了磁共振尿路造影（MRU）检查。在给予Bothdel和水30分钟后获得对比前MRU和对比后MRU。影像评价依据对比效果、影像效果、混浊评分及诊断能力。采用Wilcoxon符号秩检验进行统计分析。治疗前后影像对比、影像效果、混浊评分及诊断能力均有统计学意义的提高。
