Thyroid FNA Analysis in Dallas, TX

Southwest Diagnostic Imaging Center uses Afirma Thyroid FNA (Fine Needle Aspiration) Analysis to determine whether a lump (nodule) in your thyroid gland is likely to be benign or malignant (cancerous). Although most thyroid nodules are benign, the only way to be sure is to look closely at the cells that make up your nodule.

Thyroid FNA Test Procedure

Schedule an Appointment for a Thyroid Biopsy

First, your physician will perform a simple Fine Needle Aspiration (FNA) or biopsy. During the FNA, our radiologist will use a very thin needle (smaller than one used to draw blood) to collect cells from one or more nodules. The procedure should take only a few minutes and is usually no more painful than a tiny pinch.

Next, the FNA sample is sent to a cytopathologist - a physician who diagnoses by examining cells. If the cytopathologist determines that the nodule is likely benign or malignant, the Afirma Thyroid FNA Analysis is complete. In this case, your doctor will contact you with your final Thyroid FNA Analysis result and a recommended treatment plan if necessary.


How to prepare for a Thyroid FNA Analysis 

Most medications can be taken before this exam. However, Blood thinners (Anticoagulants) should be stopped temporarily before your thyroid biopsy. Blood Thinners can increase the risk of bleeding due to the exam. It is common to receive specific instructions regarding when to stop taking medications from your Southwest Diagnostic Imaging Center prior to the procedure. If you have any additional questions, be sure to speak with your doctor. 

You will not be required to fast on the day of your appointment. During the exam, ultrasound gel will be applied to the neck region to obtain ultrasound images. You may want to avoid wearing jewelry or form fitting clothes around the neck to avoid the water-soluble gel from getting on clothing.
