Cardiac magnetic resonance imaging (MRI) is a painless, noninvasive test. We use it to take detailed, three-dimensional pictures of your child's heart. Using these images, we can examine the structure and function of the heart and blood vessels, create images of complex heart defects and measure how well the heart is pumping blood.

Cardiac MRI is especially useful for examining anomalies (abnormalities) of the:

• Great arteries, including vascular rings
• Great veins, including patients with heterotaxy syndrome
• Broncho-arterial abnormalities such as double outlet ventricles and superoinferior ventricles
