How does the scan work?
  • You will be asked to drink a cup of water with a small amount of radio-tracer mixed into it.
  • The gamma camera will take a series of images of your chest while you are standing up and when you are on our bed. This part takes around 40min.
  • You will be asked to return for further scanning 2hours later. This will take 10minutes.
  • You then may be asked to drink another cup of water mixed with the tracer and return the following morning for a quick 10minutes image.
Is this test safe?

Yes. You will receive a small amount of radiation from the radiotracer and this is well within safety limits.

How long will this test take?

Initial scan is around 40minutes. A quick 10 minute scan 2 hours later and a possible 10 minute scan the following morning.

What are the preparations that I need to take?
  • Fast for 8 hours prior to scan.
  • Cease pro-motility medication for at least 46 hours prior to you appointment.
What should I do following the test?

We ask that you:

  1. Keep yourself well hydrated for the next 24 hours. A substantial amount of the Tc99m injection will pass out through your urine.
  2. Keep your distance from pregnant woman or children.
  3. If you are seeing your doctor or any other health professional immediately after your scan please notify them that you are still a source of radiation.
  4. We ask that you do not schedule any other appointments for yourself for the rest of the day.

If you are breast feeding, pregnant or think that you might be pregnant, please tell the staff BEFORE the injection.
