摘要
目的探讨低剂量胸痛三联CT血管造影在急性胸痛患者中的应用价值。方法选取本院2018年2月至2020年2月本院30例急性胸痛行低剂量胸痛三联CT血管造影患者作为观察组,进行单纯冠状动脉、肺动脉及主动脉螺旋CT血管成像的患者各30例作为对照组,评价成像质量。结果观察组冠状动脉共892段(理论为900段,其中8段由于发育微小或缺如未纳入到统计中),对照组894段(理论为900段,其中6段未纳入到统计中),两组冠状动脉图像质量评价比较(P>0.05);观察组与对照组主动脉图像质量评价结果分别为:升主动脉与主动脉弓1级28例、29例,2级2例、1例,3级均为0例;降主动脉:1级29例、30例,2级1例、0例,3级均为0例。两组各段主动脉成像质量比较(P>0.05);观察组与对照组肺动脉图像质量评价结果分别为:中央段1级314例、308例;2级11例、16例;3级5例、6例;周围段:1级568例、563例;2级23例、26例;3级9例、11例。两组中央段、周围段肺动脉成像质量比较(P>0.05)。结论低剂量胸痛三联CT血管造影图像质量可满足急性胸痛患者诊断需要。
Objective To explore the application value of low-dose triple rule-out CT angiography(TRO-CTA) in patients with acute chest pain. Methods During the period from February 2018 to February 2020, 30 patients with acute chest pain who underwent low-dose TRO-CTA in the hospital were enrolled as observation group, while another 30 patients who underwent simple coronary artery, pulmonary artery and aortic spiral CT angiography were enrolled as control group. The imaging quality was evaluated. Results There were 892 segments of coronary arteries in observation group(900 segments abstractly, the missing 8 segments were not included in the statistics due to small growth or lack) and 894 segments in control group(900 segments abstractly, the missing 6 segments were not included in the statistics).There was no significant difference in image quality evaluation of coronary arteries between the two groups(P>0.05).The evaluation results of aortic image quality in observation group and control group were as follows:There were 28 cases and 29 cases with ascending aorta and aortic arch at grade Ⅰ,2 cases and 1 case at grade Ⅱ,and there was no one case at grade Ⅲ in either group.There were 29 cases and 30 cases with descending aorta at grade 1,1 case and 0 case at grade Ⅱ,and there was no one case at grade Ⅲ in either group.There was no significant difference in imaging quality of each segment of the aorta between the two groups(P>0.05).The evaluation results of pulmonary artery image quality in observation group and control group were as follows:There were 314 cases and 308 cases with central segment at grade Ⅰ,11 cases and 16 cases at grade Ⅱ,5 cases and 6 cases at grade Ⅲ.There were 568 cases and 563 cases with peripheral segment at grade 1,23 cases and 26 cases at grade Ⅱ,9 cases and 11 cases at grade Ⅲ.There was no significant difference in imaging quality of central and peripheral pulmonary arteries between the two groups(P>0.05).Conclusion Low-dose TRO-CTA image quality can meet the diagnosis needs of patients with acute chest pain.
