CONCLUSION
Our study provides preliminary reference ranges for the end-diastolic
RVOT diameter in the strict transverse and sagittal views by CMR in
children and adolescents. Despite their strong correlation with the
similar 2D TTE PSAX and PLAX views, there is poor agreement between
these CMR and echocardiographic measurements. As a result, the static
bSSFP CMR images in the strict transverse and sagittal views cannot be
used to define RVOT dilatation in pediatric patients.
