Thyroid Fine Needle Aspiration

Thyroid Fine Needle Aspiration is a procedure where ultrasound is used to locate a nodule or solid area in the thyroid and obtain samples for diagnostic testing.

Procedure

  • You will lie on an exam table with your neck slightly tilted back for a short period of time.
  • A non-greasy gel will be applied to your skin during the exam.
  • The sonographer will use a hand-held transducer (probe) against your neck to obtain images of the nodule or solid area in your thyroid gland.
  • The sonographer then shows the radiologist the nodule or solid area.
  • The radiologist sterilizes the area and then numbs the area with Lidocaine to aid in any discomfort the procedure causes.
  • The radiologist then places a small needle within the area of interest and obtains samples.
  • The specimen is then sent for testing.

Preparation

  • You must be off any medication that is an anticoagulant (Motrin, Aspirin, Heparin, Coumadin or Plavix) for five days prior to this procedure.
  • Arrive 15-30 minutes prior to your scheduled appointment.
  • Bring a prescription from your doctor.
  • You may need blood work prior to the procedure.

Considerations

Let the technologist know:

  • If you are on any blood thinners.
  • If you have had any previous surgery.
  • If you have difficulty lying flat on your back.
  • Please bring a list of any medications.
