OSF St. Joseph Medical Center

Bloomington, Illinois


A biopsy is a procedure where under local anesthesia a needle will be inserted to your body to obtain a tissue specimen that will be sent to the lab for analysis. This helps the caregiver to make a diagnosis, so they can plan the best treatment for you.

The radiologist performing the procedure will use Ultrasound or Computed Tomography to help visualize the lesion.

We would like to thank you for choosing to have your procedure done at OSF St. Joseph Medical Center. Our staff is looking forward to the opportunity to serve you and your family.

Before the Procedure

Once you arrive in your room you will be asked to put on a hospital gown. You will have blood drawn for labs and an IV will be started. A nurse may also perform a physical assessment.

One of our radiology nurses will come over to explain your procedure in greater detail and answer any questions you may have. You will be asked to sign a consent form before the procedure is started.


The procedure will be done in the radiology department. A registered x-ray technologist, a radiology nurse, and a radiologist will be in the room with you during your procedure.

The nurse will apply monitoring equipment to watch your vital signs during the procedure. Images will be taken to determine the site that would be best to biopsy.

You will be awake during the procedure; every effort will be made to keep you as comfortable as possible. Medications may be given for discomfort and anxiety.

After the Procedure

You will be brought back to your room. The nurse routinely checks your vital signs and monitors your procedure site. You will be on bed rest for a minimum of three to four hours before you are able to be discharged. Please plan on being here most of the day. Upon discharge you will be required to have someone available to drive you home.

Test results

You will need to make arrangements with your doctor to get your test results (follow-up doctor’s appointment, calling the doctor’s office, etc.). Test results return to physician’s office at different intervals so please allow five days before calling for results.

When to Come and Where to Go
