Before the scan
Let the team know if you have a contrast allergy, kidney problems, or might be pregnant. Bring a list of your medicines. You may be asked to avoid caffeine on the day, and not to eat for a short time beforehand. Your hospital will give you exact instructions.
During the scan
A thin tube (cannula) is placed in your arm so a contrast liquid can be given — you may feel warm and notice a metallic taste for about a minute. If clearer pictures are needed, you may be given medicine to slow your heart rate. The scan usually takes 10 to 30 minutes, and you should allow 1 to 2 hours in the department.
The scan uses a small dose of radiation, so it is only recommended when the benefits outweigh this small risk.
