From: Pediatric cardiovascular interventional devices: effect on CMR images at 1.5 and 3 Tesla
20 month old infant prior to ( upper row) and following (lower row) occlusion of a right lower lobe pulmonary arteriovenous fistula with an Amplatzer device. Contrast enhanced MRA performed at 3T: shown are 3D volume rendered reconstructions (A,D), maximum intensity projections, sagittal plane (B,E), and procedural angiographic images (C,F). Images (A-C) are prior to embolization, (D-F) post embolization. Only minimal signal void is present and occlusion of the arteriovenous shunt is unequivocally confirmed.
