Ultrasound Biopsies

Proper treatment requires accurate diagnosis


On occasion, a biopsy may be required by your doctor to diagnose a medical problem. The goal of a biopsy is to remove a sample of tissue for testing in a laboratory. In our clinic we perform thyroid, breast and superficial tissue biopsy under ultrasound guidance.

Please remember to bring any previous ultrasound to your appointment.


You can eat and drink normally before your procedure. Take your medications as usual, but do not take aspirin, non-steroidal anti-inflammatory medicine or other aspirin-related medications for 7 days before your biopsy. You should discuss any changes to your medications with your physician.
You may be asked to remove a part of your clothes or uncover the area of interest and lie on an examination couch. You may be given a local anesthetic or a cold, numbing spray. This will only numb the area around the site of the procedure. You will remain fully awake. The imaging physician will use an ultrasound scanner to accurately guide a needle to the site of the biopsy. During the time when the needle is inserted you will be asked to hold very still and in case you have a thyroid biopsy you will also be asked not to talk or swallow. The needle will then be used to remove a tissue sample. This biopsy itself usually takes approximately 15-30 minutes. After Your Exam you may eat and drink as normal. You do not need to modify your activity level after the procedure. The tissue sample will be sent to a laboratory for examination.
