DMSA Renal Imaging

DMSA renal imaging is used to assess the function of your kidneys and can distinguish between kidney diseases and other disorders affecting the kidneys.

When you arrive for your appointment, you will receive an injection with a small amount of radioactive tracer. You will then be given a return time, which is usually two to three hours later. When you return, a series of images will be taken of your kidneys. This will take approximately one hour. Additional images may be taken if the nuclear medicine physician requests. You should schedule approximately four to five hours for a DMSA renal imaging test.


  • Bring a complete list of your medications to your appointment.
  • You may continue taking your medications as your physician has directed.
  • You may eat as usual and drink plenty of fluids the day before and the day of your appointment - unless it is being performed with anesthesia.
  • If the DMSA renal imaging is being performed with anesthesia, it is important to follow your anesthesiologists preparation instructions.
  • A TV and VCR are available for children during imaging.
  • Remember to bring the written order (prescription), for this test, given to you by your doctor.


  • Patients of childbearing age should review the pregnancy and breastfeeding guidelines.
