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.
