Abstract
Background
Patients with congenital heart disease frequently have complex cardiac and vascular malformations requiring detailed non-invasive diagnostic evaluation including functional parameters.
Objective
To evaluate the morphological and functional information provided by a novel 3-D cine steady-state free-precession (SSFP) sequence.
Materials and methods
Twenty consecutive children (mean age 2.2 years, nine boys) were examined using a 1.5-T MR system including 2-D cine gradient-recalled-echo sequences, static 3-D SSFP and 3-D cine SSFP sequences.
Results
Measurement of ventricular structures and volumes showed close agreement between the 3-D cine SSFP sequence and the 2-D cine gradient-recalled-echo and static 3-D SSFP sequences (left ventricular volumes mean difference 1.0–1.9 ml and 8.8–11.4%, respectively; right ventricular volumes 1.7–2.1 ml and 9.9–16.9%, respectively). No systematic bias was observed.
Conclusion
3-D cine MRI provides anatomic as well as functional information with sufficient spatial and temporal resolution in free-breathing infants with congenital heart disease.
