A renal MAG3 scan is a nuclear medicine test that allows doctors to see your child’s kidneys and learn more about how they are functioning.
How Boston Children’s Hospital approaches renal MAG3 scans
The Nuclear Medicine and Molecular Imaging program at Boston Children’s is committed to providing your family with a safe, comfortable and child-friendly atmosphere with:
A renal MAG3 (Mercaptuacetyltriglycine) scan is a diagnostic nuclear medicine test that allows your child’s doctor to see his/her kidneys and learn more about how they are functioning.
A radiopharmaceutical called Technetium-99m MAG3 is injected into one of your child’s veins. Technetium-99m MAG3 has a tiny amount of radioactive molecules in it.
A special camera, called a gamma camera, is used to take pictures of the kidneys once the radiopharmaceutical has been injected.
A renal MAG3 scan can help:
When you arrive, please go to the Nuclear Medicine check-in desk on the second floor of the main hospital. A clinical intake coordinator will check in your child and verify his registration information.

Your child may feel discomfort with the placement of the catheter. Our personnel are aware of the sensitive nature of the area to be tested and every effort is made to ensure privacy and to make sure the patient is as comfortable as possible.
Your child may experience some discomfort associated with the insertion of the intravenous needle. The needle used for the procedure is small. Once the radiopharmaceutical is injected and the scan is complete, the needle will be withdrawn and a bandaid will be placed over the site of the injection. The area where the injection was given may be a little sore.
Although the camera may appear large and intimidating, it does not touch your child.
We are committed to ensuring that your child receives the smallest radiation dose needed to obtain the desired result.
Once the scan is complete, the images will be evaluated for quality. If the scan is adequate, your child will be free to leave and resume normal activity.
One of the Boston Children's nuclear medicine physicians will review your child’s images and create a report of the findings and diagnosis.
The nuclear medicine physician will provide a report to the doctor who ordered your child’s renal MAG3 scan. Your child’s doctor will then discuss the results with you.
