摘要
目的分析胃肠道CT诊断期间在不同时间下使用不同剂量对比剂的效果。方法该研究主体为2018年7月—2020年7月间来该院治疗的94例胃肠道疾病患者,均行CT检查,对比剂选用显影比乐。以抽签法为基准,A组32例在扫描1.0 h前服用对比剂1.0 L,B组31例在扫描0.5 h前服用对比剂1.0 L,C组31例在扫描0.5 h前服用对比剂0.5 L。对比不同部位的充盈满意度与CT值。结果C组在各个部位的充盈满意度均低于A组、B组,差异有统计学意义(P<0.05)。3组CT值均在盆腔回肠下段值最高,A组数值为(469.65±20.34)HU,B组数值为(435.95±25.37)HU,C组数值为(262.03±37.57)HU,比较差异有统计学意义(tAC=27.395,P<0.001;tBC=21.360,P<0.001)。结论胃肠道CT扫描使用对比剂的最佳时间为扫描前0.5~1.0 h,最佳口服剂量为1.0 L,其能够获得满意的充盈度,且CT值较高。
Objective To analyze the effect of using different doses of contrast media at different times during the diagnosis of gastrointestinal tract CT.Methods The main body of this study was 94 patients with gastrointestinal diseases who came to the hospital for treatment from July 2018 to July 2020.All of them underwent CT examination,and the contrast medium used to compare the contrast.Based on the lottery method,32 patients in group A took 1.0 L of contrast agent before scan 1.0 h,31 patients in group B took 1.0 L of contrast agent 0.5 h before scan,and 31 patients in group C took 0.5 L of contrast agent 0.5 h before scan.Compared the filling satisfaction and CT value of different parts.Results The filling satisfaction degree of group C was lower than that of group A and group B,the difference was statistically significant(P<0.05).The CT values of the three groups were the highest in the lower segment of the pelvic ileum,the value of group A was(469.65±20.34)HU,the value of group B was(435.95±25.37)HU,the value of group C was(262.03±37.57)HU.The difference was statistically significant after the comparison(tAC=27.395,P<0.001;tBC=21.360,P<0.001).Conclusion The best time to use contrast agent in gastrointestinal CT scan is 0.5-1.0 h before the scan,and the best oral dose is 1.0 L,which can obtain a satisfactory filling degree and has a high CT value.
