目的探讨在多层螺旋CT尿路造影中注射造影剂后追加滴注生理盐水对提高显影率的价值。方法对36例行泌尿系统多层螺旋CT检查的病例,分别在注射造影剂后追加滴注和不追加生理盐水,对追加和不追加生理盐水的图像进行对照分析。结果生理盐水组和对照组的双侧的中段及下段输尿管平均分值生理盐水组明显高于对照组,有统计学意义。结论在注射造影剂后追加注射生理盐水能显著改善多层螺旋CT尿路造影中肾内集合系统和输尿管的显影,是提高多层螺旋CT尿路造影显影质量的有效方法。
Objective To explore the value of adding instillation of saline to improve the developing rate after injecting contrast agent in MSCT urography. Methods Thirty - six cases of urinary system multi - slice spiral computed tomography were infused with and without saline respectively after contrast agent injection. The images of the patients with or without additional saline were compared with each other. Results In the normal saline group and the control group, the bilateral middle and lower ureter mean scores in the saline group were significantly higher than those in the control group, with statistical significance. Conclusion Injection of contrast agent injection of saline can significantly improve MSCT and ureter in MSCT urography, which is an effective method to improve the quality of MSCT urography.
