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.
