A thyroid biopsy is an in-office procedure during which a small sample of tissue is removed from the thyroid gland for further testing.

Thyroid Biopsy in Long Island & Queens

Thyroid Examination

What is a thyroid biopsy?

A thyroid biopsy is a medical procedure that involves the thyroid, which is the small gland found in the front of the neck, just below the windpipe. During the procedure, a small tissue sample is taken from the thyroid gland to check for infections, cancerous cells, or other problems. A special ultrasound tool called a transducer is typically used to help guide your doctor as the thyroid sample is taken.

Why is a thyroid biopsy performed?

A thyroid biopsy may be performed in order to:

  • Determine the cause of a lump (nodule) found during a physical exam or ultrasound exam
  • Find the cause of an enlarged thyroid gland, also known as a goiter

What to expect during a thyroid biopsy

At Neighborhood Radiology Services, a needle biopsy of the thyroid is performed in-office at one of our state-of-the-art imaging centers.

During the procedure, you will be positioned comfortably, laying on your back. Depending on your needs, a local anesthetic or sedative may be given prior to the procedure to ensure you are comfortable and relaxed.

Fine needle aspiration vs. core needle biopsy

Usually, thyroid testing is done using fine needle aspiration (FNA) or core needle biopsy (CNB). During an FNA, a very thin needle is used to withdraw (or aspirate) a small amount of tissue from the thyroid for further testing. The needle used for FNA is even smaller than a needle used during a routine blood test.

A CNB is similar to an FNA, however, the needle is slightly larger and hollow. During a CNB, small cylinders (known as “cores”) are extracted from the suspicious area of the thyroid. The procedure takes slightly more time than an FNA, but is more likely to give your doctor more information because the sample is larger.

After the results of your thyroid biopsy procedure are ready, your doctor will review them with you and discuss next steps, as needed.

What are the benefits of having a thyroid biopsy?

Undergoing a thyroid biopsy with our board-certified experts has the following benefits:

  • Minimally invasive procedure
  • Little or no discomfort
  • Allows your doctor to identify the cause of a thyroid irregularity
  • Performed in one office visit
  • Does not require general anesthesia for needle biopsies (local anesthesia is sometimes used)
