摘要 目的对比研究两种不同浓度的非离子型碘造影剂在胰腺疾病多排螺旋CT增强扫描中的诊断效果。方法选取平扫怀疑胰腺病变40例,随机分配,试验组20例用碘美普尔(碘浓度为400mgI/ml)注射液,另外20例作为对照组,用碘海醇(碘浓度为300mgI/ml)注射液;测量腹主动脉、正常肝实质及胰腺病变强化前后的CT值(Hu),计算出各自的CT强化值,每个患者测量3次,计算平均值;用SPSS统计分析软件,分析测算的结果。结果动脉期及静脉期试验组腹主动脉的CT强化值:168.35±10.75,68.12±9.43;正常肝实质的CT强化值为:7.84±2.22,38.57±10.25;胰腺病变的CT强化值为:20.56±4.81,18.45±5.94;对照组腹主动脉的CT强化值为:145.09±8.74,70.34±6.55;正常肝实质的CT强化值为:8.26±1.83,51.17±10.13;病灶的CT强化值为:18.74±4.41,17.19±5.76;动脉期及静脉期两种造影剂的总体比较差异无显著性(P>0.05)。结论新型非离子型碘造影剂碘美普尔与临床已经广泛应用的碘海醇具有相同的增强效果,且碘美普尔的碘浓度较碘海醇高,需要的造影剂总量少,使用过程中未发现一例过敏反应,尤其适用于儿童及老年体弱患者。
