To assess the feasibility of cardiac magnetic resonance imaging (MRI) and angiography (MRA) at 3.0T in pediatric patients with congenital heart disease (CHD) and to compare the technical and diagnostic performance with an age-matched and clinically comparable control group imaged at 1.5T.
Forty-six patients (age 1 day to 8 years, mean 37.2 ± 32.8 months) with suspected or known CHD were evaluated (9/2008-5/2011). SSFP cine imaging, time-resolved MRA (TR-MRA), and high resolution contrast-enhanced MRA (HR-MRA) were performed. Two independent observers analyzed the MRI data for image quality, thoraco-abdominal vessel definition, and artifacts.
Cardiac MRI & MRA at 3.0T are feasible in children with CHD. Both field strengths can be used successfully for cardiac and vascular imaging; deciding which to use depends on local availability and the importance of vascular (extra-cardiac) vs. intra-cardiac imaging.
