- Abstract: Objective To study the value of multi-slice computed tomography (MSCT) combined with color Doppler ultrasound in the diagnosis of childrens congenital heart disease (CHD). Methods 85 children with CHD were selected and divided into color Doppler ultrasound group, MSCT group and combined group. All children underwent color Doppler ultrasound and MSCT, and the postoperative pathological results were regarded as the gold standard. The detection rate and the coincidence rate of children with CHD in each group were compared the characteristics of CHD images in color Doppler ultrasound and MSCT were observed the receivers operating characteristic (ROC) curve was used to evaluate the diagnostic value of each method for children with CHD. Results Compared with the MSCT group, the coincidence rate of diagnosing secundum atrial septal defect in the color Doppler ultrasound group was significantly higher. Compared with the color Doppler ultrasound group, the detection rate of patent ductus arteriosus, complex CHD and the coincidence rate of tetralogy of Fallot, ventricular septal defect and complex CHD in MSCT group were significantly increased. Compared with the color Doppler ultrasound group and MSCT group, the coincidence rate of the combined group was significantly higher. The difference was statistically significant (P<0.05) Color Doppler ultrasound was mainly used to observe the specific blood flow of CHD, while MSCT was mainly used to observe the blood vessels form of CHD. The sensitivity (99.63%), specificity (99.38%), accuracy (97.65%), positive predictive value (97.19%), negative predictive value (99.93%) and the area under ROC curve (0.996), diagnosed by MSCT combined with color Doppler ultrasound, were significantly higher than those by a single method. The difference was statistically significant (P<0.05). Conclusions MSCT combined with color Doppler ultrasound can effectively improve the accuracy of childrens CHD diagnosis.
