| ObjectiveTo investigate the diagnostic value of64-muti detector spiral computed tomography (64-MSCT)in children with complex congenital heart disease.MethodThe complex congenital heart disease data of56children were analyzed. All children with complex congenital heart disease underwent both64-MSCT and color Doppler ultrasonography. All patients were carried out angiocardiography and or surgical findings. According to the results of angiocardiography and or surgical findings,64-MSCT was compared with color Doppler ultrasonography.Result56children with complex congenital heart disease included164abnormal structures. in which64-MSCT diagnosis of right151.accurate diagnosis rate was92.07%, color Doppler ultrasound diagnosis of right130, diagnosis coincidence rate is79.27%.The intracardiac structural abnormalities were59places.49places were found by64-MSCT, but8were misdiagnosed and2were missed.57places were found by US, while2were mis diagnosed. The diagnosis coincidence rate of64-MSCT and color Doppler, ultrasonography for intracardiac malformation were83.05%and96.61%respectively.There were the obvious differences of the coincidence rates between the two methods. The extra cardiac structural abnormalities were105places,64-MSCT found102, misdiagnosed:3; color Doppler ultrasonography found73, misdiagnosed:32. The diagnosis coincidence rate of64-MSCT and color Doppler ultrasonography extra cardiac malformation was97.14%and69.52%, respectively. The coincidence rate of two examinations,64-MSCT and color Doppler ultrasonography, had obvious difference.Conclusion64-MSCT is superior to color Doppler ultrasonography in the detection of complex congenital heart disease in children, especially in detection of extra cardiac anomalies.64-MSCT should be used as a routine technique for the diagnosis imaging of children with complex congenital heart disease. |
