不同浓度的非离子型碘对比剂在多排螺旋CT肝血管成像中的增强效果比较

目的评价两种不同浓度的非离子型碘对比剂在多排螺旋CT肝脏血管成像中的增强效果。方法搜集眉山市人民医院2011年1月～5月间50例临床怀疑肝胆病变的患者行16排螺旋CT肝血管造影检查,将患者随机分为,A组(25例)对比剂为优维显370mgI/ml;B组(25例)对比剂为碘海醇300mgI/ml。使用多种图像后处理方法进行重建,分析腹主动脉、腹腔干、门静脉主干及肝实质的增强效果及显示情况。结果两组腹主动脉、腹腔干、门静脉主干及肝实质的增强效果及血管分级均以A组为优,差异有统计学意义(P<0.01)。结论在多排螺旋CT肝血管成像中应用高浓度的碘对比剂增强效果优于低浓度的碘对比剂增强效果。

The enhancement effect of non-ionic iodinated contrast media on hepatic angiography with multi-slice CT

Objective To evaluate the enhancement effect of different non-ionic iodinated contrast media in hepatic angiography using multi-slice CT.Methods 50 cases suspected hepatobiliary diseases,were underwent CT angiography of hepatic vessels by 16 MSCT,The patients were randomly divided into two groups :group A(Ultravist 370mgI/ml,25 cases) and group B(Lohexol 300mgI/ml,25 cases).Maximum intensity projection(MIP) and volume rendering(VR) were used to reconstruct the liver vessels,and the displaying status and the enhancement effect of abdominal aorta,hepatic artery,portal vein system and were analyzed.Results The displaying status and the enhancement effect of group A is better than group B.Conclusion High concentration(Ultravist 370) group has obviously higher enhancement effect for low concentration the imaging of hepatic angiography in multi-slice CT.
