提高腹部及盆部数字减影血管造影图像质量的研究

Research of improving image quality of DSA in abdomen and pelvis

目的探讨如何提高腹部及盆部数字减影血管造影(DSA)图像质量。方法回顾性评价37例(A组)患者腹部及盆部DSA图像质量,分析影响图像质量的因素,然后控制影响图像质量的因素;再行腹部及盆部DSA检查39例(B组),将两组图像质量进行比较。结果 37位患者的图像质量评分为(2.48±0.87)分;39位患者的图像质量评分为(3.61±0.68)分;后者图像质量高于前者。结论通过控制影响图像质量因素,能够提高腹部及盆部DSA图像质量。

Objective To discuss how to improve the DSA image quality in abdomen and pelvis. Methods The factors intluencmg image quality were analyzed by reviewing the DSA image quality in abdomen and pelvis of 37 cases, then the checking of abdomen and pelvis in 39 cases were carried out, and lastly the factors influencing the image quality were controlled. The image quality of two groups were com- pared. Results The image quality of 37 patients scored （2.48 ＋ 0.87）, and that of 39 patients＂ scored （3.61 ＋ 0.68）. The latter＇s image quality was higher than the former＇s. Conclusion DSA image quality in abdomen and pelvis can be improved by controlling the factors influencing the image quality.
