Cardiovascular CT imaging in congenital heart disease

CT in congenital heart disease is a rapidly evolving field. Advances in spatial and temporal resolutions, have led to a redefinition and expansion of its role. Used alongside MR, CT is a complement to echocardiography, to aid decision-making and surgical planning, and is gradually supplanting the role of diagnostic angiography. This review describes the indications for cardiovascular CT in children and adult populations, acquisition techniques, and methods of dose reduction.
