Noninvasive anatomic imaging is critical to management of pediatric congenital heart disease. With the introduction of high-pitch dual-source computed tomography (CT), comprehensive, high-temporal resolution cardiovascular imaging can now be performed without the need for breath-holding or patient sedation with very low radiation dose. In this article, we review the unique advantages of dual-source cardiac CT relative to other imaging modalities and illustrate its utility for patient management with multiple case examples.
