Multislice CT in the diagnosis of children with complex congenital heart disease / 实用放射学杂志

ABSTRACT

Objective To explore the value of multislice CT (MSCT)in the diagnosis of complex congenital heart disease (FCHD)in children.Methods 41 children cases with clinical diagnosis of congenital heart disease were collected randomly.All the children were examined with MSCT and ultrasonic cardiogram(UCG)examination,and 20 cases were examined with cadioangiography(CAG) check.All the cases were confirmed by surgery.The results of Preoperative MSCT,UCG and the CAG heart examination diagnosis were compared with surgical diagnosis results.Results Surgery confirmed 225 deformities and 1 1 5 intracardiac malformations.In the intracardiacmal malformations,the accurate diagnostic rates of MSCT,UCG,the CAG were 92.2%,99.1% and 74.4%,respectively;With surgery confirmed 110 heart malformations,the accurate diagnostic rates of MSCT,UCG,the CAG were 98.2%,84.5%,96.2%,respec-tively.The combined use of MSCT and UCG confirmed 224 correct diagnoses,the diagnosis coincidence rate reached 99.6%;The check accuracy of MSCT was highter than UCG in congenital heart disease with heart malformations(χ2 =12.962,P <0.05),The differences has statistical significance.Conclusion The check accuracy of MSCT is better in the diagnosis of congenital heart disease.The joint application of MSCT and UCG can obviously improve the accuracy of the diagnosis of congenital heart disease and congenital anoma-lies.
