HIDA scan is an examination of the gall bladder and associated ducts around the liver.
If there is a possibility that you are pregnant or if you are currently breastfeeding please inform the department before your appointment as we will likely have to re-schedule.
Whenever possible, you should attend your appointment alone, unless you need a carer to support any additional needs.
Please allow three hours for your appointment.
It is important you complete and return the enclosed green form. Please list all medication that you are taking including over the counter drugs. Some drugs need to be stopped two days before your appointment.
Firstly a cannula will be placed into a vein in your arm or back of the hands.
After this you will be taken into the scan room and positioned onto an imaging bed with a camera placed above your abdomen. Once in position you will have a small amount of radioactive tracer injected through the cannula. This will go to your liver and gallbladder and then will be excreted into the bowel. It emits gamma rays which will be detected by a piece of equipment called a gamma camera.
Immediately after injection, the first set of imaging begins which takes one hour. It is important that you remain as still as possible for your scan.
After the first set of images you will be asked to have something to eat.
Then we will carry out another scan for one hour.
All images will be checked before you leave the department. Occasionally images may be repeated or extra images acquired if necessary
You do not normally have to undress but we will ask you to remove any heavy or metal objects such as a belt.
After the appointment you can resume all usual activities. Eat as normal and keep well hydrated.
If you have young children or pregnant friends/family please limit close contact with them for the rest of the day. You can be in the same room but avoid sitting close to each other for long periods. This is to avoid them receiving any unnecessary radiation exposure.
The report will be sent to your referring doctor. They will
contact you to discuss the results. If you have any enquiries
regarding your results please contact the department where
the referral was originally made.
The radioactive tracer administered will expose you to a small amount of ionising radiation.
The risks from this radiation are very low and the benefits of having the results from the HIDA scan greatly outweigh the risk.
