| Some individuals may feel anxious while having the MRI scan performed. Those individuals who have cardiac pacemakers, metal clips that have been applied to vessels to prevent blood clot complications (ferromagnetic aneurysm clips), intrauterine metallic implants, or other metal implants, are contraindicated for MRI scans and may suffer complications if they do undergo MRI scans, since the scanner may interfere with the proper functioning of the ferromagnetic device. Another possible complication is allergy or abnormal reaction to the contrast medium that may be used during some MRI procedures, although that is rare. |
