MRI uses the detection of radio frequency signals produced by displaced radio waves in a magnetic field. It provides an anatomical view of the brain. This imaging technique has several advantages:

• There is no X-rays or radioactive material are required
• The technique safe, painless, and non-invasive.
• No special preparation is required. Patients can eat or drink anything before the procedure.
• But most importantly, this brain imaging technique provides a detailed view of the brain in different dimensions.

• Expensive to use.
• Cannot be used in patients with metallic devices, like pacemakers.
• Cannot be used with uncooperative patients because the patient must lie still.
• Cannot be used with patients who are claustrophobic (afraid of small places).
