摘要
①目的 探讨造影剂注射流量与不良反应及肝实质强化 (CT值 )效果的关系。②方法 将 2 76例行CT平扫及增强扫描病人 ,按注射流量不同分为 5组 ,3.5mL/s组 32例 ,3.0mL/s组 4 0例 ,2 .5mL/s组 77例 ,2 .0mL/s 组 6 8例 ,1.5mL/s组 5 9例。再根据造影剂类型不同分为两组 ,使用离子型造影剂 119例 ,使用非离子型造影剂 15 7例。观察各组CT增强扫描效果和不良反应情况。③结果 随造影剂注射流量的增加 ,肝实质CT值逐渐升高 ,5组间比较差异有显著性 (F =3.0 1,q =2 .91～ 4 .0 1,P <0 .0 5 ) ;离子型与非离子型造影剂组不良反应比较有显著性差异 (χ2 =4 .2 5 ,P <0 .0 5 )。④结论 注射流量越大 ,肝实质强化效果越好 ;
Objective To investigate the relationship between the injection speed of contrast medium and adverse reaction and CT value on enhanced liver parenchyma. Methods Plain and enhanced scans of spiral CT of 276 patients were divided into five groups based on injection speed: 3.5 mL/s (32 cases), 3.0 mL/s (40 cases), 2.5 mL/s (77 cases), 2.0 mL/s (68 cases) and 1.5 mL/s (59 cases); and into two groups based on contrast mediums: ionic medium (119 cases),and non-ionic medium (157 cases). Results CT value of enhanced liver parenchyma increased with the increase of injection speed, the difference between the five groups was significant (F=3.01, q=2.91-4.01, P<0.05). Significant difference also existed in adverse reactions between the results of ionic contrast medium group and those of the non-ionic group (χ 2=4.25,P<0.05). Conclusion With the increase of the injection speed, the effect of enhanced liver parenchyma gets better, but more adverse effects will occur. The incidence of adverse effects of ionic contrast agent is higher than those of non-ionic one.
