DMSA scan (dimercaptosuccinic acid)

What is a DMSA Scan?

This is an examination of the kidneys which gives information on their size, shape and position. Their function may also be measured. DMSA stands for dimercaptosuccinic acid. This substance has a radioactive tracer attached which localises in the kidneys and is detected (scanned) by a Gamma Camera.

What is this scan used for?

A DMSA scan looks at the size, shape and position of the kidneys. It can check for any scars or abnormal areas of development and find out how well one kidney is working compared to the other.

How can I prepare for this procedure?

• Please eat normally and hydrate well.
• You do not need a full bladder for this procedure.
• You will not need to undress as long as there are no metal items on your clothing.
• If there is any chance you could be pregnant, or if you are breastfeeding, please inform the Department at least 24 hours before your appointment.

What happens during the procedure?

• There are two appointment times for this scan.
• At your first appointment a small amount of radioactive tracer will be injected into a vein in your arm or hand, which is like having a blood test. The tracer takes two hours to localise in the kidneys.
• You can leave the hospital and return at your second appointment time for the scan.
• The scan of 30 minutes will take place at your second appointment time
• You will be lying down for your scan, but you will not be totally enclosed.
• When the scan has finished you may go home.
• There are no restrictions regarding driving. 

Paying for your procedure
