The purpose of this study is to show sites of uptake of gallium citrate in your body. It is most commonly used for localisation of tumour (e.g lymphoma) or infection/inflammation. This will help the doctor understand your condition, and give appropriate treatment as required.
On arrival you will be given an injection containing a small amount of radioactivity into a vein in your arm. You will be asked to return to the department 3 days later for the scan. After emptying your bladder, you will be required to lie down on a couch, and pictures will be taken of your body using a gamma camera. You do not normally need to take off clothing. Only removal of jewellery or metal objects is required. In order to get good pictures, the camera will be close to you, and you will have to remain still. Pictures will be taken as the camera moves over your body (a planar image) followed by a SPET scan, when the camera moves around part of your body. The procedure will take 60-75 minutes. Further pictures will be taken the following day (day 4), usually for the same length of time.
If you are pregnant, or you think you might be pregnant, you need to inform your doctor or the Nuclear Medicine staff before attending your appointment. In general, exposure to radiation during pregnancy should be kept to a minimum and it may be necessary to postpone your scan. The present guidelines recommend that breast-feeding should be stopped following the injection.
We would prefer that you do not bring more than one person with you. It is advisable not to have a pregnant woman or a small child with you. This is to avoid exposing them to unnecessary radiation. It is also preferable to avoid prolonged close contact (hugging a child / sitting a child on your knee for more than half an hour) for 3 days following the injection.
You may eat, drink, and take your medication as normal.
You may feel a slight pinprick from the injection needle. Our doctors will be available during your stay in the department to answer any queries and to provide medical cover in case of any side effect from the injection we give you (please note that side effects are extremely rare).
The amount of radioactivity you receive in this study is strictly within the recommended national level. At this level, the benefit to you from a diagnosis of your condition outweighs the risk (negligible) of any harm associated with the radiation you will receive.
You may eat as normal. The more fluid you drink the better, as the radioactivity is passed out in the urine. No extra precautions need to be taken when passing urine.
The Nuclear Medicine doctor will report on the study and the result will be sent to the doctor who requested the study. He/she will be able to discuss the results with you in relation to other tests you may have had.
