MRI of the brain is a detailed scan using magnets, showing the soft tissue of the brain in fine detail. It is used to investigate conditions like stroke, tumors, seizures, persistent headaches, and other brain issues. Before the scan, remove all metal, tell staff about any implants, pacemakers, or metal fragments, and discuss any contrast allergy. The modality uses magnets, not X-ray radiation, and is safe with some metal implants. MRI of the brain takes often 30–60 minutes.
