CT/Ultrasound Guided Needle Biopsy

What Is a Biopsy?

A needle biopsy is a procedure in which a needle is inserted through the skin into an organ or mass inside the body to obtain a sample of tissue. The biopsy is done to assist your provider in identifying the cause of abnormal organ function or to determine if a mass is benign or cancerous.

Before the Procedure

Providing safe, quality patient care is our highest priority. For the best experience please properly prepare for your appointment:

• For some biopsies, you will be instructed not to eat 8 hours before and drink 4 hours before your procedure is scheduled. You may take medications with a sip of water. Other biopsies you may be able to maintain your normal diet; be sure to follow instructions given at time of scheduling.
• Certain medications cannot be taken prior to this procedure; your doctor will provide instructions if you need to adjust your medication.
• Do not bring children with you to your appointment. For their safety children are not allowed to accompany you in the exam room. Staff are unable to monitor children.

During the Procedure

A team of nurses, imaging technologists and a provider (doctor, physician assistant or nurse practitioner) will explain and perform the procedure.

• Imaging Technologist will utilize CT or Ultrasound to find the precise area for biopsy.
• Some biopsies require sedation and a nurse places monitors on your arm and hand to measure your blood pressure, heart rate and oxygen level. You may receive oxygen during this procedure.
• Provider injects numbing medication into the skin prior to inserting the biopsy needle.
• The biopsy needle may make a “clicking” noise during the procedure.
