DMSA (Dimercaptosuccinic Acid) Scan
Understanding DMSA (Dimercaptosuccinic Acid) Scan
What is DMSA (Dimercaptosuccinic Acid) Scan?
The DMSA (Dimercaptosuccinic Acid) Scan scan uses a radioactive chemical known as dimercaptosuccinic acid, to create specialised pictures of the kidneys for assesing their health. This chemical is provided intravenously and emits gamma radiations. It accumulates in the regions of the renal tract and kidneys having abnormal activity. Most active and brighest spots are called hot spots and indicate an abnormal activity. These are visualized with special cameras against less bright/ cold spots.
This scan is used for diagnosing a urinary tract infection (UTI), pyelonephritis and scarring caused due to vesico-ureteric reflux.
It is commonly recommended to children having urinary tract infections.
Rarely, some people can show allergic reaction to the injected chemical. Pregnant women are not advised to undergo this test as gamma radiations may affect the fetus.
