Editor's Note
The Food & Drug Administration (FDA) on March 12 issued a Safety Alert on the potential for increased artifact associated with magnetic resonance angiography (MRA) imaging for follow-up of certain post neurovascular embolization coil procedures.
When MRA is performed on patients implanted with neurovascular embolization coils containing 304V stainless steel, the images may contain larger than expected artifact or image voids, which can result in inaccurate diagnoses and subsequent inappropriate medical decisions.
