Magnetic resonance imaging of the heart.

Magnetic resonance imaging of the heart has an established role in the assessment of congenital heart disease, the aorta, the pericardium and cardiac tumours. It supplements the information provided by echocardiography and Doppler ultrasound scanning and provides reliable studies of blood flow. Recent developments include myocardial perfusion imaging using real-time techniques and progress towards non-invasive coronary angiography.
