| Research Abstract |
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.
