Objectives: To measure pulmonary artery and aortic calibers, and calculatingmain pulmonary artery to ascending aorta ratio in healthy children, to verify the adult ratio of1:1. Study Design: Observational study. Place and duration of study: Radiology Department,Combined Military Hospital, Peshawar from 15 July 2015 to 14 July 2016. Methodology:Chest CT cans of 283 healthy children, with no history or predisposing causes of pulmonaryhypertension, performed between July 2015 and July 2016, were retrospectively studied.Diameters of pulmonary artery and aorta were measured on CT chest, at the level of bifurcationof the main pulmonary artery, and the ratio of pulmonary artery to ascending aorta wascalculated. Results: The average diameter of the main pulmonary artery, right pulmonary arteryand left pulmonary artery were 19 mm, 12.1 mm and 12.2 mm respectively. The diameter of theascending aorta was determined to be 12.2 mm and descending aorta was 13.67 mm. Ratio ofthe main pulmonary artery to ascending aorta was 1.06, which was higher than the adult ration,usually taken as <0.9. Conclusion: The measurement criteria devised for early detection ofpulmonary hypertension have different set of values when considering pediatric population ascompared to adults. Main pulmonary artery to ascending aorta ratio is significantly higher inhealthy children of all ages as compared to adults. CT scan is an excellent minimally invasivemodality in evaluation of the mediastinal vasculature.
