Tell your technologist at the time of your exam if you have any metal or electronic devices in or on your body including, but not limited to:
- Watches or jewelry
- Cell phones or PDAs
- Implanted electronic devices
- Implanted metallic joint prostheses, artificial heart valves, cochlear implants, hearing aids or metallic dentures.
- Tell your technologist and your doctor if you are pregnant or suspect you may be pregnant.
- Your doctor may postpone the exam or choose an alternative exam.
- No preparation is necessary prior to your exam.
Some patients may feel anxious due to the confining nature of the MRI scanner. If you feel this way, talk to your doctor. He or she may feel it necessary to prescribe a sedative prior to your exam to help you relax.
Your doctor or radiologist may request that your MRI scan be enhanced via the use of contrast material. If contrast is required, the technologist will start an intravenous (IV) line in your hand or arm to administer the contrast.
Most reactions are minor such as itchiness, hives, and nausea or vomiting. In very rare instances, an allergic reaction may cause swelling in your throat or other areas of your body. Tell your technologist or doctor immediately if you experience any of these symptoms during or after your exam.
