What is a Meckel’s scan?

A Meckel’s scan is a nuclear medicine test that uses a small amount of radioactivity to show a problem in the small intestine. Meckel’s diverticulum is a pouch on the wall of the lower part of the intestine. It is a birth defect. The pouch may contain tissue that is the same as the stomach or pancreas. The symptoms may include bleeding and pain.

Do I need this test?

A doctor will have checked the request to make sure this is the best test for you. If you have any concerns or would like further information, please contact the department where you are having your scan. If you do not understand why you need to have this scan please speak to the doctor who referred you.

Is it safe?

The materials (radionuclides) used to find any problems are generally safe. They have short half-life and leave the body naturally, like through urine. So we can do your scan we need to inject “radiopharmaceutical”. This means a small amount of radioactivity has been mixed with a medicine. The small radiation risk is outweighed by the information that we will get from the scan.

Do I need to prepare for my Meckel’s scan?
  • Generally you will need to fast for 3-4 hours before your scan.
  • All other instructions will have been discussed with you by telephone.
  • Wear loose fitting garments for your comfort.
What if I am pregnant or breast-feeding?

Due to radiation risk to unborn child, this scan should not be carried out if you are pregnant. If you know that you are pregnant, or there is any chance that you may be pregnant contact the department on following numbers. Your scan will need to be postponed. Also let us know if you are breast-feeding. We have special instructions for you:

Cumberland Infirmary, Carlisle: 01228 814701
West Cumberland Hospital, Whitehaven: 01946 523456

What will happen?

Your Injection

A small amount of liquid (radioactive tracer) will be injected into a vein in your arm or hand using a small needle. The ‘pinprick’ of the needle may hurt a bit but that is  all. This is similar to a blood test you might have had in the past. You will be asked to lie flat on a special couch. The scan will start after the injection.

Your Scan

The scan is done using a hybrid scanner called SPECT/CT system. It has of two camera head detectors and a CT scanner. It is not a fully closed system but the camera heads will be close to you. These detectors have touch sensors so they stop moving when they sense body. This means it is unlikely to touch you.

We will try our best to make you feel comfortable and relaxed. A technologist will explain the procedure before starting the scan. They will be in the control room at all times. You will not feel anything during the scan. There are no after effects. If you feel any discomfort at any time point please let us know.

The imaging can take about an hour. It is very important that you keep still during the scan. Please speak to us before your appointment if you think you will find this difficult.

After Your Scan

When scan is finished the technologist will get you off the scanner. You can continue all your normal activities unless you have been told not to.

A tiny amount of radioactivity will still be left in your body but this will be a risk to other people. The radioactivity will break down on its own. For the rest of the day, we would suggest that you:

  1. Try to keep any time that you spend close to pregnant women, babies and small children as short as possible. There is no need to stop giving children essential love and care.
  2. Drink plenty of liquids. This will help clear the radioactivity quicker.
Travelling Abroad

It is safe for you to travel abroad after your scan. Many airports and seaports have very sensitive radiation detectors. It is possible that the very small amount of radioactivity left in your body could set off an alarm as you go through security. If you are going to travel abroad within 1 week after your scan, it could be helpful to take with you something to explain that you have recently had a nuclear medicine scan. This could be your appointment letter or some other official confirmation from the department where you had your scan.

Your Results 

A nuclear medicine physician/radiologist will report your Meckel’s scan. The report will be sent to the doctor who asked for your scan rather than to your GP. Unless your GP requested the scan. This is because the doctor who asked for your scan will have all the results from other tests. They will be able to tell you how the result of your scan affects your care plan.
