CI patients who undergo MRI with a magnet in situ may experience complications, especially when imaged below the head. Most complications may be resolved without surgery. Diagnostic usefulness of non-cranial MRI is not likely to be limited by presence of the magnet, while a magnet may prevent clinically useful brain imaging. Obtaining MRI with the magnet in situ avoids the cost and risks associated with multiple surgeries to remove and replace the magnet or the entire implant.
