Objective To evaluate the effect of hepatic artery angiography on liver perfusion using two contrast agent with different concentrations and injection rates and analysed the nursing factors. Methods 104 patients underwent liver perfusion examination by 320 slices CT with Omnipaque 350 and Ultravist 370 contrast agent, and then they were respectively divided into two groups based on different injection rates (4, 6ml/s).Hepatic artery CT peak value and vascular reconstruction image quality were evaluated; care factors were summarized. Results There were significant differences in liver perfusion between Omnipaque 350 and Ultravist 370 contrast agent (P <0. 01). The hepatic artery CT peak value with 4 ml/s injection rate was significantly smaller than that with 6ml/s. Conclusions The hepatic artery CT peak value and vascular reconstruction image quality with high injection rate and contrast agent concentration in liver perfusion examination by 320 slices CT arrive 3 class or above. Good nursing measures will improve image quality and success rate of examination.%目的 比较肝脏灌注检查中两种不同对比剂浓度和两种不同注射速率对肝动脉CT显影效果的影响,并分析护理影响因素.方法 104例患者,分别用欧乃派克350和优维显370,再随机分两小组不同流率:4 ml/s和6 ml/s的注射速率进行320排CT肝脏灌注检查,检测肝动脉CT峰值和血管重建图像质量;总结护理影响因素.结果 欧乃派克350与优维显370的肝动脉CT峰值差异具有统计学意义(P<0.01);4 ml/s注射速率肝动脉CT峰值低于6 ml/s的注射速率肝动脉CT峰值,两者之间差异具有统计学意义(P<0.01).结论 320排CT肝脏灌注检查中不同对比剂浓度和注射速率对肝动脉显影及图像质量的对比中,高浓度及高注射速率在肝动脉灌注中CT值及图像质量达到3级以上,良好的护理措施能解除影响图像质量的因素,也大大提高了图像质量和检查成功率.
