MR imaging of pseudoaneurysms in aortocoronary bypass graft

Aneurysm formation may complicate aortocoronary saphenous vein bypass grafts. Because of multiplanar imaging capabilities and the potential for flow evaluation, magnetic resonance (MR) is useful as a noninvasive diagnostic technique. Two cases of pseudoaneurysm formation were evaluated by MR and demonstrate the clinical value of this modality.
