Imaging of congenital heart disease (CHD) starts in the intrauterine period by fetal echocardiography. The anatomy and physiology are confirmed postnatally by transthoracic echocardiogram. However, complex CHDs require further imaging to delineate anatomy for further management and surgical intervention. Cardiac magnetic resonance imaging (MRI) and cardiac chest tomography (CT) complement the role of transthoracic echocardiogram in delineating further details of anatomy and physiology in the neonatal period. This review covers the basic sequences and terminologies used in cardiac MRI and cardiac CT. A brief description of the indications and the ideal modality of imaging is described, including the limitations of each modality of imaging.
