不同质量浓度碘海醇在腹部CT增强动脉期显示的应用

The Application of Iohexo of Different Concentrations in Arterial Pase Dsplay with Enhanced Abdominal CT

目的:比较腹部CT增强动脉期显示中不同质量浓度碘海醇的应用。方法:回顾性选取2016年3月至2019年2月青海省西宁市第一人民医院疑似腹部病变患者289例,依据碘海醇质量浓度分为低浓度组(300mgI/mL,n=145)和高浓度组(350mgI/mL,n=144)两组,统计分析两组患者动脉期扫描时间、图像质量、不良事件发生情况。结果:两组患者动脉期触发时间、实际扫描时间之间的差异均无统计学意义(P>0.05),腹主动脉CT值之间的差异也无统计学意义(P>0.05)。两组患者动脉期扫描腹主动脉噪声、信噪比之间的差异均无统计学意义(P>0.05)。在不良事件发生率方面,低浓度组为1.4%(2/145),高浓度组为5.6%(8/144),前者显著低于后者,差异有统计学意义(P<0.05)。结论:腹部CT增强动脉期显示低浓度碘海醇的应用安全效果较高浓度碘海醇好,值得推广。

Objective:To compare the application of iohexol of different concentrations in arterial phase display with enhanced abdominal CT.Methods:289 patients with suspected abdominal lesions from March 2016 to February 2019 in the First People's Hospital of Xining City were retrospectively selected.According to the mass concentration of iohexol,they were divided into two groups:low concentration group(300mg/mL,n=145)and high concentration group(350 mg/mL,n=144).The scanning time,image quality and adverse events of the two groups were statistically analyzed.Results:The differences of trigger time of arterial phase and actual scanning time between the two groups were not statistically significant(P>0.05),nor in the CT value of abdominal aorta(P>0.05).The differences of noise and signal-to-noise ratios of abdominal aorta in arterial phase between the two groups were not statistically significant(P>0.05).The incidence of adverse events was 1.4%(2/145)in the low concentration group and 5.6%(8/144)in the high concentration group.The former was significantly lower than the latter,and the difference was statistically significant(P<0.05).Conclusion:The application effect of iohexol of low concentration in arterial phase display with enhanced abdominal CT is safer than iohexol of high concentration,so it is worthy of promotion.
