Role of 128 slice MSCT angiography in evaluation of congenital extra-cardiac intra-thoracic vascular anomalies in children

CG gated MSCT angiography is an accurate modality for demonstrating extra cardiac structures in complex CHD. It provides important complementary information to TTE with regard to extra cardiac vascular structures and coronary artery anatomy. This modality may reduce the need for high radiation dose invasive diagnostic cardiac catheterization.
