Usefulness of magnetic resonance angiography for diagnosis of scimitar syndrome in early infancy.

This study evaluated the feasibility and accuracy of the magnetic resonance angiography (MRA) evaluation of scimitar syndrome in early infancy in 4 subjects. MRA imaging was successful, with excellent imaging quality to evaluate the main and lobar pulmonary artery branches, lobar pulmonary veins, scimitar vein, and systemic-pulmonary collateral arteries in all subjects. There was good agreement between findings with MRA, x-ray angiography (n = 3), surgical inspection (n = 3), and autopsy (n = 1).
