CT肺动脉血管造影中低剂量对比剂诊断肺动脉栓塞的价值

Value of Low Dose Contrast Agent in Diagnosis of Pulmonary Embolism in CT Pulmonary Angiography

目的对肺动脉栓塞患者于螺旋CT肺动脉的血管造影中采用低剂量对比剂进行诊断的价值进行分析。方法对本院2017年10月—2018年6月诊治的肺动脉栓塞102例患者临床资料加以分析,均行螺旋CT肺动脉血管造影,且按照对比剂不同剂量分成两组,将应用常规剂量51例患者设为对照组,将应用低剂量51例患者设为观察组,对两组诊断价值进行对比、分析。结果观察组左右肺静脉的血管强化CT值均比对照组低,且不良反应总发生概率比对照组低(P <0.01)。结论对肺动脉栓塞患者于螺旋CT肺动脉的血管造影中采用低剂量或者常规剂量对比剂进行诊断价值相当,但低剂量可减少不良反应的发生,值得临床应用。

Objective To analyze the value of low-dose contrast agents in the diagnosis of pulmonary embolism in patients with pulmonary embolism.Methods The clinical data of 102 patients with pulmonary embolism from October 2017 to June 2018 were analyzed.All patients underwent angiography of spiral CT pulmonary artery and were divided into two groups according to different doses of contrast agent.51 patients with routine dose were set as control group,and 51 patients with low dose were set as observation group.The diagnostic value of the two groups was compared and analyzed.Results The angiographic CT values of the left and right pulmonary veins in the observation group were lower than those in the control group,and the total incidence of adverse reactions was lower than that in the control group(P<0.01).Conclusion In patients with pulmonary embolism,the use of low-dose or conventional dose contrast agents in the angiography of spiral CT pulmonary arteries is comparable,but low-dose can reduce the incidence of adverse reactions,which is worthy of clinical application.
