DMSA scan

DMSA scan is a type of nuclear medicine imaging test that uses a small amount of a radioactive substance, called a tracer, to examine the kidneys. The tracer used in a DMSA scan is called dimercaptosuccinic acid (DMSA), which is absorbed by the kidneys and allows them to be seen clearly on the scan.

Procedure[edit | edit source]

The DMSA scan procedure involves the injection of the DMSA tracer into a vein, usually in the arm. The tracer then travels through the bloodstream and is absorbed by the kidneys. A special camera, called a gamma camera, is used to take images of the kidneys as they absorb the tracer. The scan usually takes about 3 to 4 hours to complete.

Uses[edit | edit source]

A DMSA scan is used to evaluate the function and structure of the kidneys. It can help diagnose a number of kidney conditions, including kidney infections, kidney stones, and kidney damage. It can also be used to assess the kidneys before and after kidney transplant surgery.

Risks[edit | edit source]

As with any medical procedure, there are some risks associated with a DMSA scan. These include an allergic reaction to the DMSA tracer and exposure to a small amount of radiation. However, the benefits of a DMSA scan usually outweigh these risks.

Preparation[edit | edit source]

Before a DMSA scan, patients are usually asked to drink plenty of fluids to help the kidneys work more effectively. They may also be asked to avoid certain medications that could interfere with the scan.

Results[edit | edit source]

The results of a DMSA scan are usually available within a few days. The images from the scan can show any abnormalities in the kidneys, such as areas of damage or infection.
