Sinus venosus atrial septal defect with partial anomalous pulmonary venous return: diagnosis with 64-slice spiral computed tomography at low radiation dose.

The use of computed tomography is often debatable for pediatric patients because of the associated radiation exposure. Using a state-of-the-art 64-slice spiral computed tomography unit, we demonstrate the feasibility of lowering the radiation dose without losing essential diagnostic information in a case of a 2-year-old boy with a rare congenital heart defect.
