The purpose of our study was to determine the value three-dimensional reconstructed helical CT in assessment pulmonary arteries infants and children with complex congenital heart disease.Twenty patients were examined contrast-enhanced CT. Three-dimensional reconstructions performed multiplanar reformations, maximum intensity projection, shaded-surface display. Correlation made 19 echocardiograms 14 cineangiocardiograms. All imaging studies reviewed independently for following parameters: caliber main branch their confluence, presence stenosis, number aortopulmonary collaterals, patency vascular shunts conduits. Surgical confirmation, which used as reference standard, available all patients.Helical accurate angiocardiography revealing stenotic nonconfluent central collaterals (overall test sensitivity, 90%; specificity, 100%; accuracy, 93%).Three-dimensional rendition did not improve accuracy shown equally well angiography, but showed thrombosis more directly. Echocardiography least technique artery anatomy (accuracy, 65%), primarily because a relatively large technically unsatisfactory assess parameters.Helical reconstruction is superior echocardiography noninvasive disease. Helical may be complementary occasionally substitute diagnostic portion cardiac catheterization cineangiocardiography.
