Abstract:
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 1 762 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 1 762 children,912 was found with CLA(912/1 762,51.76%).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.
