What Is a Biopsy Done by Ultrasound?
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
ξ You may have lab tests done on the day of the test. We may draw blood for a platelet
count and INR. This will either be done at your physician’s office or in the outpatient lab
1 hour prior to the biopsy.
ξ If you are taking blood thinners such as Coumadin (warfarin), heparin, Plavix ,
ibuprofen, naproxen, or daily aspirin, you may be instructed to stop these medications
prior to the biopsy to prevent bleeding during and after the biopsy.
During the Biopsy
Be sure to tell the radiologists if you have any allergies (contrast dye, antibiotics, anesthetic
After a review of your x-rays the radiologist, using ultrasound, will mark an area that will show
the best place to insert the needle. Next, the area will be cleaned with special soap. The skin
around the site will be numbed with Lidocaine so you will have little pain. Most patients feel
pressure, but not major pain.
Under ultrasound, the tissue sample is withdrawn using a special needle. One to three samples
may be taken. The tissue sample is sent for exam under the microscope or to pathology for
After the Biopsy
ξ After the local anesthetic wears off, you may feel some discomfort at the site. Your pain
should not be severe, but is often described as somewhat sore. If you are having
discomfort, use Tylenol up to 3 times daily. You may talk to the doctor or nurse if you
have questions about the dose. The pain should go away within the first 24 hours.
ξ Tell the nurse if you have new pain, nausea, vomiting, or chills.
ξ A bandage will be placed over the biopsy site. You may remove it and shower 24 hours
after the biopsy.
