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.
