MRI is entirely safe for humans, there are practically no contraindications. The one limitations are matched to the provision of pacemakers and metal implants. An active magnetic field can heat metals in your body or disrupt electronic mechanisms.
Indications to the procedure
MRI from the mental abilities are needed if:
Frequent and severe headaches that can not be addressed with medication.
