DMSA scan

A DMSA scan is used to check how well your kidneys are working. It is also used to show any potentially scarred areas in your kidneys, causing them not to work well as they should.

If you have had a urine infection in the four months before your appointment date, please ring us as we may need to change your appointment.

If there is a possibility that you are pregnant or you are currently breastfeeding please inform the department before your appointment.

Whenever possible, only the patient should attend their appointment unless you are a parent accompanying a child or a carer for a patient with additional needs.

A radioactive substance will be injected into a vein, usually in your arm or the back of your hand, which is then absorbed by the kidneys.

It can take between two and three hours for the radioactive substance to reach the kidneys. During this time, we ask you to leave the department and return at a later time on that same day or your scan. If this is not possible please let us know.

You will be required to lie still on our imaging bed, while three pictures are taken from the front and back. Each picture can take up to 10 minutes.

You do not normally have to undress but we will ask you to remove any heavy or metal objects such as a belt.

Occasionally images may be repeated or extra images obtained if necessary. Depending on how many pictures are needed, the scan will take approximately 45 minutes.

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.

After completion of the appointment, you can resume all usual activities. Eat as normal and keep well hydrated.
