Renal Scan/Renogram

Renal Scan/Renogram

This exam shows how well the kidneys are functioning.

Preparation

  • Please arrive 15 minutes prior to your appointment.
  • Bring a list of current medications.
  • Please arrive well hydrated, 2-3 glasses (16 to 24 ounces) of water, before exam.

Procedure

  • You may be asked to drink some water upon arrival in the nuclear medicine department.
  • An IV will be started in one of your arms.
  • You will be placed on a scanning table with a gamma camera in position to image the kidneys.
  • The nuclear medicine technologist will inject a small amount of radioactive tracer through the IV and begin the imaging process immediately.
  • Imaging will require you to lie flat on your back, remaining relatively still for at least 30-40 minutes.
  • It is possible that the doctor may order the exam with a diuretic, which may require additional imaging.
  • Total time for the exam may be between 1 and 2 hours.

After the procedure

  • You will follow up with your ordering doctor.

Considerations

  • If you are pregnant or suspect you may be, contact your referring doctor.
  • Tell the technologist if you are planning to travel out of the country.
