From: Pediatric cardiovascular interventional devices: effect on CMR images at 1.5 and 3 Tesla
Image artifact due to Flipper detachable embolization coils in a 5 year old male with heterotaxy, transposition of the great arteries, hypoplastic left ventricle, double outlet right ventricle, bilateral superior vena cavae and hyposplenia with prior history of multiple embolizations. Contrast enhanced MR angiography was performed at 3T. Reconstructions in the coronal, sagittal and axial planes show extensive areas of signal void, up to 10cm in size, from embolization coils in the lower posterior mediastinum and right hepatic lobe (green arrows).
