Comparison of 16-multidetector-row computed tomography and angiocardiography for evaluating the central pulmonary artery diameter and pulmonary artery index in children with congenital heart disease.

Purpose The pulmonary artery (PA) is involved in most congenital heart diseases; and in these patients it is necessary to evaluate precisely the PA configuration and development. The accuracy of 16 multidetector row computed tomography (16-MDCT) in evaluating the central PA was evaluated.
