Abstract:
Objective To evaluate the clinical diagnostic value and limitation of MRI and contrast enhancement MRA (CE-MRA) in congenital heart disease of children. Methods Three hundred patients with congenital heart disease underwent CE-MRA. 173 were confirmed by operation. The results of MRA and CE-MRA were compared with operation data. Results 196 (86.0%) intracardiac malformation including septal defect and valve anomaly were diagnosed correctly by MRI within 228 abnormalities which were confirmed by operation. 101 (96.2%) extracardiac malformation including great vessels stenosis and anomalous connection were diagnosed correctly by MRI and MRA within 105 abnormalities which were confirmed by operation. Conclusion MRI and CE-MRA are very accurate diagnostic method for extracardiac malformation. CE-MRA is the best sequence for congenital heart disease.
