Make sure that the consent form is signed by the child’s parents or legal guardians.

Note and report all allergies. Be sure to assess for a history of iodine or seafood allergies before the procedure if a contrast medium is to be used.

Children requiring life-support equipment, including ventilators, require special preparation; contact magnetic resonance imaging (MRI) staff ahead of time.

Explain to the child and his parents that there’s no exposure to radiation during MRI.

Tell the parents that, because no radiation is used, they may read or talk to their child in the imaging room during the procedure.

Inform the parents that a young child will need to be sedated because of the need to remain motionless during the procedure.

Tell the parents and child that he may eat or drink as usual before and after the procedure; no food or fluid restrictions are necessary before MRI.

A claustrophobic child may require sedation or an open MRI to reduce anxiety.

Because no metal can go in the scanner, assist the child in removing hair clips, jewelry, and other metal items as necessary.

Advise the child that he’ll be asked to remain still during the procedure.

Prepare the child for the movements and the loud, clicking noises made by the scanner; reassure him that the machine won’t touch him.
