Abstract
The purpose of our study was to determine the value of three-dimensional reconstructed helical CT in the assessment of the pulmonary arteries in infants and children with complex congenital heart disease.Twenty patients were examined with contrast-enhanced helical CT. Three-dimensional reconstructions were performed with multiplanar reformations, maximum intensity projection, and shaded-surface display. Correlation was made with 19 echocardiograms and 14 cineangiocardiograms. All imaging studies were reviewed independently for the following parameters: the caliber of the main and branch pulmonary arteries and their confluence, the presence of stenosis, the number and caliber of aortopulmonary collaterals, and the patency of vascular shunts and conduits. Surgical confirmation, which was used as the reference standard, was available in all patients.Helical CT was as accurate as angiocardiography in revealing stenotic and nonconfluent central pulmonary arteries and in revealing aortopulmonary collaterals (ov...Keywords
