Image Guided Biopsy


What Is an Image Guided Biopsy?


An image guided biopsy is a procedure to remove abnormal tissue or fluid from the body, so it can be examined under a microscope for signs of damage or disease. Your doctor will insert a needle through your skin and into the abnormal tissue. An imaging technique such as computed tomography (CT) or ultrasound is used to help guide the radiologist’s instruments to the appropriate site.


Before the Biopsy


  • No food or liquids for 6 hours prior to the procedure. However, you may take all regular medications as scheduled with small sips of water.
  • It is required that you arrange for a relative or friend to drive you home after the procedure.
  • Report any medications you are taking to the radiology nurse, including “blood thinners”, such as aspirin, Plavix, Lovenox, Coumadin, Pradaxa, Xarelto, or Eliquis. Your physician may advise you to stop taking a “blood thinner” for a specific period of time before your procedure.
  • Prior to your procedure, your blood will be tested to determine if your blood clots normally.
  • Report any allergies to the radiology nurse, especially those to local anesthetic medications.
  • Women should always inform the x-ray technologist if there is any possibility that they are pregnant. Many imaging tests are not performed during pregnancy so as not to expose the fetus to radiation.

During the Image Guided Biopsy


  • You will be positioned on the CT or ultrasound table and images will be taken to find the best location for biopsy.
  • The skin is cleaned with an antiseptic solution and the selected site is covered with a large sterile sheet.
  • You will feel a slight pin prick when the local anesthetic (numbing medicine) is injected in the area.
  • Using CT or ultrasound as a guide, the doctor inserts the needle through the skin and advances it into the abnormal tissue and removes samples. Several specimens may be needed for complete analysis.
  • After the sampling, the needle is removed and a bandage is placed over the procedure site.

Potential Risks and Complications

  • Bleeding at the procedure site
  • Infection at the procedure site
  • Injury to an adjacent nerve, blood vessel, or muscle

After the Biopsy


  • Get plenty of rest for the remainder of the day after your biopsy. You may return to light activity the day after the biopsy.
  • Avoid heavy lifting or strenuous labor for 3 days after your biopsy.
  • Eat and drink normally. Increased fluid intake is recommended.
  • Mild pain, discomfort, or bruising at the procedure site is expected. You may take over-the-counter Tylenol for any pain you may experience.
  • You will have a small bandage over the site. You may remove the bandage in 3 days and leave the site dry and exposed. You may shower, but do not have a tub bath for 3 days.

Call your doctor if you have any of the following:

  • Signs of infection at the procedure site, such as redness, swelling, or a fever.
  • Bleeding from the procedure site.
  • Worsening, severe pain near the procedure site.
  • Fainting or feeling lightheaded.

If any further questions or complications arise and you do not know what to do, please call the radiology department at Summit Healthcare at (928) 537-4375, ext. 6549. For questions after hours please ask for ext. 6332.

Getting your biopsy results may take a few days. When the results are ready, your doctor will discuss them with you.
