Neck lymph node ultrasound and biopsy
During a neck lymph node biopsy, your doctor uses an ultrasound scanner to help them take a small amount of lymph node tissue using a fine needle. Ultrasound scans use high frequency sound waves to create a picture of a part of the body. The ultrasound scanner has a probe that gives off sound waves. The sound waves bounce off the structures inside your body, and the probe picks them up. The probe links to a computer that turns the sound waves into a picture. You normally have this test as an outpatient procedure in the hospital’s imaging department. Why
