Thyroid Ultrasound and Thyroid Fine Needle Aspiration Biopsy
Thyroid ultrasonography and fine needle biopsy are among the most reliable methods for diagnosing thyroid conditions, playing a vital role in determining the nature of nodules. Performed with modern technology and expert clinical experience, these procedures are the most effective way to protect your thyroid health and detect potential risks early.
What is a Thyroid Ultrasound and How is it Performed?
A thyroid ultrasound (thyroid sonography) is a safe, radiation-free imaging method used to evaluate the size and structure of the thyroid gland and detect the presence of nodules. Using sound waves, this procedure is highly effective in identifying cystic (fluid-filled) or solid (firm) formations. During the procedure, a special gel is applied to the neck area, and detailed images are captured using an ultrasound probe. The process is completely painless, and results are typically evaluated by the specialist on the same day.
What is Thyroid Fine Needle Aspiration Biopsy (FNAB)?
Commonly known as a fine needle biopsy, thyroid fine needle aspiration biopsy is the “gold standard” diagnostic method used to determine whether a thyroid nodule is benign or malignant. Under ultrasound guidance, a very thin needle is used to aspirate (vacuum) cell samples from the nodule for pathological examination. This procedure does not require local anesthesia, takes only a few minutes, and allows patients to return to their daily activities immediately.
When are Ultrasound and Biopsy Necessary?
Thyroid screening and diagnostic procedures are critical in the following cases:
- Thyroid Ultrasound: Recommended for symptoms such as a palpable lump in the neck, difficulty swallowing, hoarseness, or when abnormalities appear in thyroid hormone tests during routine check-ups.
- Fine Needle Biopsy: Recommended for nodules that show suspicious features on an ultrasound (irregular borders, calcification, etc.), have a diameter larger than 1 cm, or when previous biopsy results were inconclusive. These procedures are vital for the early detection of thyroid cancer.
The Importance of Thyroid Diagnosis and Follow-up
Thyroid ultrasound is used not only for initial diagnosis but also to monitor nodules over time. Periodic follow-ups check for growth in existing nodules or the formation of new ones. A definitive cellular evaluation of suspicious nodules is provided through the fine needle biopsy, meticulously performed by Dr. Burcu Meryem Atak Sançmış. Based on the pathology report, a decision is made for surgery, medication, or regular observation.
What to Expect After the Procedure?
No special care is required after a thyroid ultrasound. Following a fine needle biopsy, there may be very slight sensitivity or temporary bruising at the injection site. Dr. Burcu Meryem Atak Sançmış ensures a comfortable experience by providing detailed information before and after the procedure. Once the biopsy results are ready, a personalized treatment plan is developed to define the next steps.
Frequently Asked Questions
Does every thyroid nodule require a biopsy?
No. Not every nodule needs a biopsy. The decision is made by your doctor based on the size of the nodule, its ultrasound appearance, and the patient’s individual risk factors.
Can goiter be diagnosed with an ultrasound?
Yes. Both diffuse (general enlargement) and nodular goiter can be clearly visualized and staged using ultrasound.
Are thyroid ultrasounds and biopsies safe during pregnancy?
Yes. Since ultrasounds do not use radiation, they are completely safe during pregnancy. If medically necessary, a biopsy can also be performed during pregnancy under expert supervision.
Is surgery necessary if the biopsy result is "benign"?
Usually, no. However, if the nodule is very large, causes difficulty breathing or swallowing, or is a cosmetic concern for the patient, surgical options may be considered. In suspicious cases, a repeat biopsy may be requested.
Is there a risk of serious bleeding during a fine needle biopsy?
No. Because the needles used are extremely thin, the risk of serious bleeding is very low. Occasionally, slight and temporary spotting may occur at the entry site.
