Renal Scan with MAG3

There is no special preparation for this exam.  You may eat, drink and take any medications that you need to prior to this exam.

What to Expect:
Upon arrival on our reception area, you will be greeted and escorted back to the Nuclear Medicine suite by one of our team members.  Once there, your Technologist will explain the procedure to you, discuss your symptoms (if any) along with your medical history and start an IV in your arm (or hand).

You will be positioned lying on back on our imaging table. Your Technologist will inject a radiopharmaceutical (MAG3) into your vein.  The injection has no side affects and you will not feel different from it at all.

The scan takes approximately 30 minutes to obtain.  As you lie on our imaging table the camera will take pictures of your kidneys.  For maximum comfort a is pillow placed under your head and knees and you are covered with a warm blanket.  Feel free to bring along your favorite DVD movie or music CD to use during your procedure or you can choose one from our selection.

Once imaging is complete, your Technologist will evaluate the image for quality, remove your IV, address any issues or concerns that you may have and escort you back to the reception area.  The images are read by a Radiologist (doctor) and the results are dictated, transcribed and sent to your ordering physician within 3 business days.  The ordering physician will provide results to you.

Common reasons to perform a Renal Scan with MAG3 include (but are not limited to):

  • Evaluation of renal function in patients with asymmetric renal disease.
  • Evaluation of the vascular supply to the kidneys.
