Objective To investigate the clinical value and accuracy of DSCT in the assessment of the pulmonary arteries in patients with complex congenital heart disease.Materitals and methods DSCT and echocardiography was performed respectively in patients with complex congenital heart disease.49 patients were collected, whose pulmonary arteries were abnormal verified by operation.7 aspects were concerned,including pulmonary artery trunk, left and right pulmonary arteries, the confluence of pulmonary, stenosis of pulmonary, patent ductus arteriosus and major aortopulmonary collateral arteries.The results were compared with each other to evaluate the ability of manifestation of the pulmonary arteries and reveal their relevance.Result The pulmonary arteries could be clearly observed from original images and multi-planar reconstruction images at different angles.DSCT was superior to echocardiography for the non-invasive assessment of pulmonary artery anatomy(overall test parameters of DSCT: sensitivity 93%, specificity 97%,PPV 99%, NPV 83%; overall test parameters of echocardiography: sensitivity 79%, specificity 80%, PPV 92%,NPV 57%).A high correlation was obtained from measurements (coefficient of correlation: main pulmonary artery 0.96, left pulmonary artery 0.97, right pulmonary artery 0.92).Conclusion Disregarding heart rate,DSCT is superior to echocardiography for the assessment of pulmonary artery anatomy.
