Ultrasound Guided Biopsy
In Ultrasound/Abdominal Imaging
Your doctor has scheduled a biopsy to be done on ________________. Please report to
Radiology (G3/3) on the 3rd floor at ____________. Before the biopsy, our doctors will explain
what will happen, answer any questions, and ask you to sign a consent form.
What Is a Biopsy Done by
A biopsy removes a small tissue sample
from the area of concern. The procedure
is guided by the use of ultrasound.
Ultrasound looks at deep structures by
making an image from the sound waves
which reflect back from the tissues. No
radiation or “x-ray” is used.
How to Prepare for the Biopsy
1. You are prepared for your
procedure in our prep and recovery
area before your biopsy. We start
an IV and take your blood
pressure, pulse, respirations, and
temperature. This makes sure you
are safe to have the procedure and
can be given sedation.
2. You may have lab tests done on the
day of the test. We may draw
blood for a platelet count and INR.
This will be done when your IV is
3. Please tell us if you take blood
thinners such as Coumadin®
(warfarin), Heparin, Plavix®,
Pradaxa®, Ibuprofen, Naproxen,
low molecular heparin injections
(Fragmin® or Lovenox®) or daily
aspirin. Someone from ultrasound
will call your doctor and let you
know when you should stop taking
it and when you should start again.
4. If you have diabetes, please call
your doctor to discuss how your
medicine doses should change
before this procedure. Test your
blood sugar more often when you
can’t eat as well as before the
procedure. If your blood sugar
level is low (less than 70 mg/dl) or
you have symptoms, eat some
glucose tablets or drink 4 ounces of
a clear liquid with sugar. Always
recheck your blood sugar level to
make sure it stays above 70. We
may still be able to do the
procedure unless you need to eat
solid food to keep your blood sugar
at a normal level. If the blood
sugar ever gets too high or too low
and you can’t bring it back to
normal, call your local doctor or
5. Stop eating 6 hours _________
before the procedure. You may
drink clear liquids until 2 hours
__________ before the procedure.
This includes black coffee, tea,
water, and juices without pulp that
you can see through.
6. You are awake for the
procedure. You may be given
Midazolam and Fentanyl
medicines in your IV to help
mildly sedate you before the
procedure. Please let the nurse
know if you have sleep apnea.
Someone must drive you home if
you receive any medicines. You
should not drive or make
important personal or business
decisions until the next day.
During the Biopsy
Be sure to tell the radiologists if you
have any allergies (medicines,
antibiotics, anesthetic agents, etc.).
An IV will be used to give you fluids.
After a review of your x-rays the
radiologist, uses an ultrasound and
marks an area that will show the best
place to insert the needle. After this, the
area is cleaned with special soap. The
skin around the site is numbed so you
will have little pain. Most patients feel
pressure, but not major pain.
Under ultrasound, the tissue sample is
taken out using a special needle. One to
three samples may be taken. The tissue
sample is then sent for exam under the

at the site. Your pain should not be
severe, but is often described as

times daily. You may talk to the
doctor or nurse if you have
questions about the dose. The pain
