- Avoid heart stimulants such as cigarettes, cola, tea, coffee as well as chocolate or any other caffeine-containing food on the day of your appointment, as the scan captures images between heart beats and a regular rate makes the imaging process easier.
- Remove chains, necklaces and nipple piercings.
- Put on a hospital gown.
A medical imaging technologist will position you on the exam table with your arms extended above your head. Three electrodes will be placed on your chest. The areas where the electrodes will be placed may have to be shaved to increase adherence. Shields are then placed over the genitals and breasts (for women) to prevent these areas from being exposed unnecessarily to radiation. You will be given instructions about when to hold your breath as the images are acquired.
A radiologist will analyze the exam and send the report to your treating physician. There are no side effects.
