摘　　要：目的观察Turbo-Flash模式CT扫描对于显示婴幼儿动脉导管韧带钙化(CLA)的价值。方法回顾性分析1762例临床疑诊肺部、气管及支气管病变婴幼儿(月龄1~36个月)Turbo-Flash模式胸部CT资料,按月龄以3个月为间隔将患儿分为A~L组;判断有无CLA并观察其CT表现,比较各组CLA发生率及CLA密度,分析二者与月龄的相关性。结果1762例中,于912例检出CLA(912/1762,51.76%),各组CLA发生率为34.29%(12/35)~59.35%(92/155)。CLA均位于肺动脉干左侧至主动脉左锁骨下动脉起点水平之间的动脉韧带内,其形态各异,密度为(183.36±50.16)~(295.80±105.91)HU。CLA发生率在A~F组与月龄呈正相关(r=0.945,P=0.002)、在F~L组与月龄呈负相关(r=-0.765,P=0.045);其密度在A~F组与月龄呈正相关(r=0.775,P=0.020)、在G~L组CLA与月龄无明显相关(P=0.593)。结论Turbo-Flash模式CT扫描对于显示婴幼儿CLA的临床应用价值较高。Objective To explore the value of Turbo-Flash mode CT scanning for displaying calcification of ligamentum arteriousum(CLA)in infants and young children.Methods Chest CT data obtained with Turbo-Flash mode scanning of 1762 infants and young children(aged 1 to 36 months)with suspected lung,trachea or bronchi lesions were retrospectively analyzed.Children were divided into group A to L according to age at 3-month intervals.CLA was evaluated and its CT manifestations were analyzed.The incidence of CLA in each group was counted,the density of CLA was measured,and their correlations with age were observed.Results Among 1762 children,912 was found with CLA(912/1762,51.76%).The incidence of CLA in group A—L was 34.29%(12/35)—59.35%(92/155),respectively.All CLA located in the arterial ligaments between the left side of pulmonary trunk and the origin level of left subclavian artery of the aorta and shaped differently.The density of CLA in group A—L was(183.36±50.16)—(295.80±105.91)HU,respectively.The incidence of CLA in group A—F was positively(r=0.945,P=0.002),while in group F—L was negatively correlated with age(r=-0.765,P=0.045).Meanwhile,the density of CLA in group A—F was positively correlated with age(r=0.775,P=0.020),but no significant correlation between CLA density and age was found in G—L group(P=0.593).Conclusion Turbo-Flash mode CT scanning had high clinical application value for displaying CLA in infants and young children.
