You may be given specific instructions at the time of your booking prior to your scan. This may include fasting or drinking a certain amount of fluid.
These are designed to increase the effectiveness of the scan. If you are unsure as to your instructions, contact the booking clinic. Don’t forget to mention whether you are taking medications, which can affect the timing of your scan.
It is important that these instructions are followed, or your test may have to be rescheduled.
