Pediatric Nuclear Medicine
Lasix Renal Scan


Test date____________________ Test time_____________________
You will arrive at the American Family Children’s Hospital (AFCH) and check in with the
Radiology Imaging Pavilion. Our staff will take you to where the test will be done in the Nuclear
Medicine section of Radiology.

What is a Lasix Renal Scan?
This radiology exam looks at the function
and drainage of the kidneys. The scan can
find out if there is an obstruction or
blockage.
How do I prepare for this test?
Bring something to help your child lay still
for the study. You may bring books,
movies, or if young enough, a bottle to drink

Ask your doctor if your child needs
sedation. If needed, we will call you the day
before. You will be told what time your
child should stop eating and drinking. If
your child does not need sedation, babies
may have their normal feeding and older
children may eat and drink before the scan.
What should you and your
child expect?
After you check in your child, you will be
taken to the Diagnostic and Therapy Center
Campground where an IV will be started.
The IV will be used to provide fluids and
medicine. In most cases, if your child is 10
years old or younger they will have a
catheter placed into the bladder. Your


doctor can tell you whether your child will
need this. We will have a Child Life
Specialist on hand to help you and your
child through these steps and the study.
How will this be done?
Our staff will take you to the UWHC
Nuclear Medicine Department for your scan.
We will explain the process to you and
answer any questions you may have. One or
two parents or caregivers may stay with the
child during the scan.

Your child will need to lie flat on a table for
about 45 minutes. It is very important to be
still during this test. The person doing the
scan may need to swaddle the child to
ensure a good study. A special scanning
camera (located beneath the table) is used to
capture the image.

A series of pictures will be taken during
which time two medicines will be given
through the IV. The first medicine is a small
amount of a radioactive substance to get
images of the kidneys and the second
medicine, lasix (furosemide), will be given
part way through the study to help drain the
kidneys. This series of pictures will help
assess the function and drainage of the
kidneys.



The catheter and IV will be removed after
the imaging is complete. When your child is
stable, you will be able to go on to the
follow-up appointment or home. You will
discuss the results of the study with your
child’s doctor at a later time.
How will I feel afterwards?
The imaging is painless, except for the
discomfort of having an IV and catheter
placed. The furosemide can give you an
urgent need to go to the bathroom. The
longer we can take pictures before you need
to use the bathroom the better. This urgency
is less noticeable when a catheter is in place.

What are the risks?
Many people worry when they hear that the
substance used in this test is radioactive.
The amount used in this test is so small that
there should be no side effects.
