- A. You must shampoo your hair thoroughly tonight to remove oil and dirt.
- B. You will need to hold your head completely still during the examination.
- C. You may take fluids until about 8 a.m. Then we will give you a special radiopaque drink.
- D. We will partially shave your head tonight so that electrodes can be attached securely to your scalp.
