Make sure you remember to bring any previous films or reports to the appointment. Wear warm comfortable clothing. You will also need to:
- Thuốc - take your medications as normal
- Advise of pregnancy or breastfeeding - let the service know if you are pregnant or breastfeeding
Chuyện gì sẽ diễn ra?
You will receive a small injection of a radioactive tracer into a vein. It takes about three hours for the tracer to circulate in your body. During this time, you can go and do other things. When you return, pictures of the kidneys are taken using a special camera for about 45 - 60 minutes. During the scan you must lay very still and breathe normally.
Điều gì sẽ xảy đến tiếp theo?
There are no after-effects from having a renal scan. The small dose of radiation in the injection is about the same as you would get from a back X-ray.
Once it is finished, you can go home. You are able to drive immediately after the test. Your results will be sent to your GP or specialist.
