Patients who have undergone a Bi-Directional Glenn (BDG) procedure have been seen to present with increased systemic venous pressure and reversal of flow in the superior vena cava. 4D MRI velocity mapping allows for the quantification and visualization of flow dynamics within the thoracic circulation. Here we report our initial findings on 4D flow imaging in BDG patients. This approach may lead to a greater understanding of the hemodynamics that may contribute to complications following BDG procedures.
